IN MEMORIAM Keith Patterson
C h a i r ’s M e s s a g e
am writing to you having just completed the last of my grading for my grape and wine chemistry class and after seeing the last of our graduating students depart. We graduated a record number of students this year (47), and I am happy to say that all have
leaders in viticulture and enology through education and research
been successful at finding employment. In this issue of The Catch Wire you will find many stories about our students and this year’s graduating class. I am extremely proud of our students and the work that they have completed. I am also thankful to be working with such a committed and talented faculty and staff. They have worked to transfer knowledge and character to our students and I believe that Fresno State is producing extremely capable people.
In addition to the activities related to our students, our spring 2013 edition of The Catch Wire contains updates on our vineyard development. With the recent successful completion of negotiations intended to promote industry investment into the Department of Viticulture and Enology by returning a portion of future profits that result from investment, a considerable amount of interest has been raised. If you have driven by our vineyards recently you will notice that we have just completed the replanting of a 20-acre block. The establishment of this block was made possible by the generous investment of time and energy of many. It goes without saying that our program is successful because so many people outside of this university believe in our mission and want to be part of it. As we expand The Catch Wire we will be bringing in not only the news and stories that are going on in the department, but stories covering the people and places that are connected to this department and are part of our extended family. There are several such stories in this issue. If you have stories to tell or people to mention, please let us know, as we want to pass them along! For now, enjoy the spring edition of The Catch Wire.

V i n e y a rVd i nReeydaev ee n ltoipnmMeon t i o n r de lRoepdmev In January, we reported in the Catch Wire that the Fresno State Ag Foundation and our Viticulture and Enology Industry Advisory Board had signed an agreement that would increase the long-term sustainability of the vineyards and viticulture program at Fresno State. As a result, a new model for
alumnus and senior viticulturist for West Coast Grape Farming, has also been a lead advisor on the project. “This first phase has been made possible because of the generosity of several industry partners, beginning with West Coast Grape Farming,” said Mark Salwasser. Plans are underway to recognize all donors using university-approved signage.
creating university-industry partnerships and a plan for redeveloping the vineyards was formed to ensure that Fresno State remains the premier institution for hands-on training in the vineyard.
“Partnerships like these continue to be the cornerstone of our program’s success. We are grateful that our industry is committed to helping us make improvements in the vineyard that will ultimately benefit our students and the grape and wine industry,” said Dr. Jim Kennedy, department chair.
In February, the vineyard redevelopment plan was launched with a major commitment from West Coast Grape Farming, a division of Bronco Wine Company. Mark Salwasser, vineyard manager, and recently hired assistant vineyard manager, Ryan Hessler, have been busy working closely with Sal Arriola, chief agricultural officer at West Coast Grape Farming, to coordinate industry donations and the scheduling of multiple vendors, crews, supplies, and materials needed to replant approximately 20 acres of French Colombard winegrapes.

STEP BY STEP â€Ś. WE GROW
Industry Investment The Department of Viticulture and Enology wishes to recognize West Coast Grape Farmingâ€™s commitment to making the Fresno State Vineyards the premier location for training students and the grape and wine industry. The Vineyard Redevelopment Plan is an ongoing project in the Fresno State Vineyards. A complete list of contributors will be recognized in subsequent issues of the Catch Wire. 7
F r e s n o S t a t e W i n e r y o n To p 1 0 L i s t For many years, the Fresno State Winery has been on our university’s Top 10 list of things that make Fresno State unique. As the first commercially bonded winery on any U.S. university campus, the winery has a solid reputation for being the “home of tomorrow’s winemakers.” But with all of the accolades that our students and winery have received over the years, we remain forward-thinking and are committed to building upon our successes. Under the leadership of Dr. Jim Kennedy, chair of the Department of Viticulture and Enology, Fresno State is always looking for ways to enhance our ability to prepare students for careers in the wine industry. “We take our role as educators seriously and are excited about our new courses, additional faculty and staff, and the overall direction we are headed,” said Kennedy.
New winery and marketing manager, Kevin Smith, promotes the Fresno State Winery’s new wine club, “Unleashed” at Vino Italiano on April 18.

One example of this growth is the arrival of Kevin Smith, our new wine business marketing manager. And has he ever been busy! Since March, Kevin has already developed and launched a new wine club called, “Unleashed,” hosted a successful Vino Italiano event in the Fresno State Winery on April 18 for the community, and released the 2012

A r e Yo u R e a d y t o G e t U n l e a s h e d ? Fresno State Wines Unleashed! We heard your plea and have responded with wine! The Fresno State wine club has been re-designed, re-named, and re-launched! “Unleashed” was coined to represent the spirit of exploration and unbridled affection we find in every student winemaker and every bottle of Fresno State wine. Kevin Smith is passionate about conveying the energy and cutting edge styles of the student enologists, combined with the quality winemaking practices that make us an award-winning winery.

B r y a n A n t h o n y, M . S . am still in touch with today. The network of viticulturists and enologists that I developed while in school has been invaluable to me in my professional life. But, no doubt the best experience I had while attending Fresno State was meeting my future wife, Marit Arana, who was working on her masters in Animal Science,” he added.
If you have been to any one of our viticulture and enology events, you probably have seen or met Bryan Anthony. His commitment to Fresno State’s viticulture and enology program is evident in the many ways he gives back to this institution. Bryan came to Fresno State in the fall of 1985 and after meeting with Vincent Petrucci, former professor of viticulture, he decided to pursue a master’s degree in plant science.
Today Bryan continues to support the viticulture and enology program as a member of the Fresno State Viticulture and Enology Alumni. For many years, he served on their Board of Directors and also held the office of president from 2005 to 2012.
Fortunate to have been hired as a student assistant by Dominic Pecchenino, former vineyard manager (1985), Bryan soon became a big part of the viticulture team at Fresno State. In the next few years he worked as the acting table grape technician in the university vineyards and was also a teaching assistant for two years for former viticulture professor Sayed Badr.
“Being involved with the Alumni Association has been rewarding. Working with other alumni and friends of the program to support the V. E. Petrucci Library has been a worthwhile endeavor,” he said. Bryan is employed by Diageo Chateau and Wine Estates as a grower relations manager, responsible for grape sourcing and grower management in the San Joaquin Valley. Previous employment includes positions as senior viticulture manager and senior viticulturist for Wente Family Estates where he managed 1,900 acres of vineyards in the Livermore
As a student, Bryan enrolled in a number of vineyard enterprise projects including Thompson Seedless, Zinfandel, and Flame Seedless. “One of the best experiences I had during my time at Fresno State was participating in the vineyard projects. They provided me with hands-on opportunities to learn the practical side of grape growing,” said Bryan.
Valley and supported the Director of Viticulture with the technical aspects of vineyard production in Livermore and Monterey County. Prior to Wente, Bryan held a number of viticulture positions at E & J Gallo Winery, where he focused on production viticulture, winegrape quality, and grower education.
He completed his M.S. degree in 1990 and was fortunate to receive funding for his masters project through the USDA Research Station in Fresno where he worked in the Postharvest Pathology Lab headed by Dr. Doug Phillips.
Thank you, Bryan, for all you do for our students and the viticulture and enology program at Fresno State!

R o n M e t z l e r, B . S . How can you thank someone who has been a part of the viticulture and enology program for over five decades? Well, Dr. Jim Kennedy, department chair, did his best as he surprised Ron Metzler with the Department of Viticulture and Enology’s Outstanding Alumni Award during the graduation dinner on May
And finally, Ron is an active member of the grape and wine industry who has also served on numerous committees. Always interested in learning and in promoting the central valley’s grape and wine industry, his affiliations include the Central California Winegrape Growers, San Joaquin Valley Viticulture Tech Group, Farm Bureau, California Association of Winegrape Growers where he is a founding member, and the Fresno State Ag Foundation, just to name a few!
16, 2013 at Fresno State.
Ron has helped guide our research and academic programs at Fresno State with genuine interest and Fresno State pride. Through his dedication and service, he has been a role model and has made significant and lasting contributions to our viticulture and enology program for which we are truly grateful. On May 16, Dr. Kennedy tried to find the words to let him know how much we appreciate what he has done for the viticulture and enology program, and for the grape and wine industry as a whole. Ron’s message to the graduates encouraged them to get involved in their industry, and to find a way to give back.
The story of Ron’s service began in the 1950s when he was a student in Fresno State’s viticulture program. He graduated in 1959 and has remained an active member of the viticulture and enology alumni, as well as an integral part of the university and the grape and wine community by serving in many different roles.
The inscription on the plaque commended Ron for his dedication, contributions, and heartfelt service to the viticulture and enology programs at California State University, Fresno.
Ron continues to be an active member of the Viticulture and Enology Alumni Association and has devoted a tremendous amount of time on their Board—most recently as treasurer.
In May, Ron and his wife, Diadre, relocated to Arizona where they will enjoy retirement. His interest in Fresno State will no doubt continue, and we look forward to hearing from them often. With gratitude and friendship, we wish them well!
He has demonstrated his commitment to the V. E. Petrucci Library by serving on its Library Committee. Ron is a charter member and former chair of department’s Industry Advisory Board—a board meets regularly and provides guidance to academic and research programs within department.

Wednesday, March 27 Our visit to Caymus Vineyards (center photo) was amazing. They literally wined and dined us! Chuck Wagner personally gave us a tour of their cellar (barrel tasting!) and their estate vineyard. He told us about his family history and how the vineyards and winery have developed along the way. Joe Wagner (winemaker and Chuck’s son) elaborated on the winemaking process and how they are finding ways to make popular wines even between vintages. They shared many wines and Janet Thomas and Mike Gioia had a wonderful Mediterranean lunch prepared for us. They really pulled out the stops!

We had a blast there, camped on their property, grilled tri-tip, and made pineapple upside-down cake! Tuesday, March 26 Today we headed up to Shafer Vineyards in Stags Leap where Elias F e r n a n d e z , winemaker, and their head of viticulture showed us their vineyards and gave us a tour of their gorgeous and very modern winery. We also visited Markham Vineyards in St. Helena where Bryan Del Bondio, president, gave us a wonderfully entertaining personal tour of the winery. He told us all about their history and told many stories about the photos in their rock n– roll museum. They have a great team who were more than gracious!
Our last visit was to Maldanado, a small winery just outside Calistoga where Hugo Maldonado and his family told us how they dug for two years to create their hillside cave/winery. Theirs was a romantic story of a family of vineyard workers who created a winery. Hugh (second generation) is the winemaker and his wife, Lydia, is Horacio’s cousin. They were great to us and told us how they are very simple winery that is family and quality-focused.
Next we visited Flora Springs where winemaker Paul Steinhauer gave us a tour of their winery and caves. The wines were nice and Paul had a lot to say about how they were made. Viticulture Club member Horacio Lopez-Segura spent last summer working for a vineyard management company that

Pe t r u c c i L i b r a r y On Sunday, April 20, runners from all over Fresno and Clovis gathered in the Fresno State Vineyards to run, walk, or stroll for a good cause. Hosted by the Viticulture Club, this 2nd annual 5K event raised $2,000 for the V. E. Petrucci Library in the Department of Viticulture and Enology at Fresno State. The 5K and the library itself is named for Vincent E. Petrucci, founder of the Viticulture and Enology programs at Fresno State and a legend in the field. Under the direction of Britt Foster, our librarian, the library supports and continues Petrucci’s legacy of excellence in academics, research, and extension in the heart of California's Central Valley. Viticulture Club members were out in force, helping to make this community event a success. And that it was! For a fee of $35, participants received a “Papa Petrucci” shirt, bottled water, and a lot of fun! Best of all, Professor Petrucci not only kicked off the event, he also gave a “high-five” to each 5K participant as they crossed the finish line.

O u t s t a n d i n g G r a d u a t e S t u d e n t A c h i eve r When it came time to celebrate her academic achievements in May, Jennifer Barak had many reasons to smile. In addition to receiving the Department of Viticulture and Enology’s 2013 Outstanding Graduate Student Achiever award, she was awarded with the 2013 Jordan College of Agricultural Sciences and Technology’s Outstanding Thesis Award on May 18 at the commencement ceremony at the Save Mart Center. Jennifer grew up in Los Angeles, California. After high school and junior college she transferred to Fresno State in order to pursue an enology degree, in which she found the perfect blend of art and science. During her undergraduate career, while
waiting to turn 21, she studied abroad in London, and was able to complete a 3-month internship in Veneto, Italy where she lived and worked in the winery and shadowed the viticulturist and visited vineyards across the Italian countryside. In the summer of 2010, she had the opportunity to travel to Europe again as a Fresno State student where she spent a month studying winemaking in Switzerland, Italy and France. After receiving her B.S. degree in enology from Fresno State in 2011, Jennifer began to pursue her master’s degree in viticulture and enology under advisor Dr. James Kennedy.
Jennifer Barak, M.S. As a graduate student Jennifer successfully performed several research projects in the field of grape and wine phenolics and designed, executed, and concluded a research project that was published in the Journal of Agricultural and Food Chemistry. Her thesis title is HPLC Retention Thermodynamics of Grape and Wine Tannins. “The Department of Viticulture has given me so much—not only the base of knowledge required to pursue my chosen career, but lifetime friends and faculty and staff who I will always be able to turn to during my career,” said Jennifer. ‘I can’t wait to start my career and get my chance to give back!”

As a double major, Lauren remained very active in the Delta Gamma Fraternity where she served as their Director of Public Relations and Vice President of Social Standards. In the Department of Viticulture and Enology, she was an active member of the Enology Society where she held the offices of Social Chair and
Lauren Billys, B.S. President. She says that it is through these extracurricular activities and commitments that she found a unique set of relationships and was able to enhance her educational experience at Fresno State.
“Becoming a student in the Department of Viticulture and Enology has been the best decision I made at Fresno State. The faculty cares about the progress of its students and it’s invested in our successes and futures. My fellow classmates have pushed me to study harder and become more involved in the program. I love the challenges presented by this department and the encouragement to succeed that is found in the faculty, staff, and students. I couldn’t be more thankful for the opportunity to work alongside this impressive group,” said Lauren.
In addition to enology, Lauren also has a talent and passion for the sport of three-day eventing which is a competitive genre of equestrian competition. As a result she joined the Puerto Rican Eventing Team and rode for them in 2011 in the Pan American Games in Guadalajara, Mexico and in various international competitions throughout the United States. Lauren’s immediate plans are to pursue her passion in equestrian competition but may consider returning to graduate school in the new few years. For now she has an opportunity to compete in a series of international competitions in the upcoming Olympic cycle for 2016.
Congratulations to Lauren for her academic achievements and leadership in our department.

Pa r t n e r i n g w i t h C A RT This spring, Eli Carlo, a teacher from the Center for Advanced Research and Technology (CART) in Clovis, California contacted Dr. Susan Rodriguez, director of the Department of Viticulture and Enology’s Sensory Lab, about working with some of his students on a project involving the influence of perception. CART is a state-of-the-art research and technology facility where eleventh and twelfth grade students from the Clovis and Fresno Unified School Districts attend high school. CART students are selected into this rigorous educational program that includes learning plans, individualized attention, and a coordinated sequence of projects. Students must ultimately design and complete projects in collaboration with partners from the local, national, and international community. Courses are taught in four career clusters by teams of instructors. Mr. Carlo is a teacher in the Psychology and Human Behavior cluster.
Two students on the CART team give a presentation at Fresno State to Dr. Susan Rodriguez and her sensory team.
The Influence of Perception: Impact on Color of Wine tion: Impact of Color on Wine.” These students, of course, were not allowed to come in contact with the wine, but were responsible for all other aspects of the study.
“Four of Eli Carlo’s students were interested in designing a perception test based on a very complicated study by noted University of Bordeaux professor, Denis Dubourdieu. In researching this project, the students learned about our Wine Sensory Lab at Fresno State and wanted to partner with us on their study,” said Dr. Rodriguez.
The students began with an interest in knowing whether color can change one’s perception of taste. This particular subject has also been an area of interest and study for members of the grape and wine industry. In fact there has been much industry debate over the power of perception, and the influence of sight, smell, and taste on the human brain when evaluating wine. According to Dubourdieu, “The wine’s color appears to provide significant sensory information, which misleads the subjects’ ability to judge flavor.”
Rodriguez and her team were very impressed with the four students and their teacher, and agreed to run the tests for them in the Sensory Lab this spring. CART students Aaron Caldwell, Chloe Campos, Emiley Flores, and Rebecca Nelson chose the following title for their project, “Influence of Percep-
Rodriguez’s team regularly conducts blind tastings in the Sensory Lab at Fresno State—where information about the wine, including items such as variety, color, label are withheld from the evaluator. In fact, her team often uses black wine glasses in their studies and training exercises to mask the color of the wine that is being presented to tasters. For the CART study, two glasses of white wine were used. Rodriguez’s team used food dye in white wine to make it appear as red wine before presenting the wines to the participants in a blind study. After compiling the data, the students were responsible for writing a final report and presenting their findings at a research symposium at CART in April.
Rodriguez’s sensory team gets the “red wine” ready to give to participants to sample
Rodriguez indicated that it was a great experience working with these talented high school students. “I hope that we contributed to their project in a way that helped them learn and build their skills,” she said. The department hopes this recent collaboration will lead to future partnerships with CART. “We’d love to be able to work with and attract top-notch high school students like this to the Department of Viticulture and Enology at Fresno State, and to the grape and wine industry,” said Jim Kennedy, Department Chair.
Participants in the study sample the “white wine” and use a list of descriptors to describe what the wine tasted like
CART is the Center for Advanced Research Technology As stated on their web site, “The Center for Advanced Research and Technology (CART) is the most comprehensive, state-of-the-art education reform effort at the secondary level to date. The CART combines rigorous academics with technical, design, process, entrepreneurial, and critical thinking skills.” For more information, visit www.cart.org Watch the students’ debriefing video on YouTube!

As more and more grape growers harvest mechanically, wineries and growers are confronted with the challenges of identifying rot in the slush of grape and juice arriving at winery sugar stands. Drs. Roy Thornton and Susan Rodriguez, heading a team of several research assistants, are working to
Drawing on their microbiology backgrounds, Thornton and Rodriguez were interested in finding a method to objectively quantify rot, even within the slurry of juice and berries. Their approach is based on the idea that rot-causing microorganisms produce volatile compounds, which can be detected through a variety of analyses. Working with Dr. Gary Takeoka of USDA-ARS Western Regional Research Laboratory, Thornton and Rodriguez are identifying and quantifying the volatile compounds
develop a method of rot quantification that is both time- and cost-affective. Thornton and Rodriguez, who have been with the Department of Viticulture and Enology at Fresno State since 2001, began investigating methods of rot quantification in 2008 in response to industry needs. Rot present in the vineyard can cause off-odors and other negative effects in the finished wine, making elevated rot percentages a major concern for wineries. Growers are also impacted by rot, as price per ton can be influenced by rot levels-- entire loads may even be rejected for high rot levels. Rot amounts are currently estimated through visual inspection of grapes sampled from berry gondolas. The amount of rot per load is then calculated based on the percentage of rotten berries present in the sample. This visual assessment has some degree of subjectivity, and is made increasingly difficult by

produced by common molds found in San Joaquin Valley vineyards: Rhizopus stolonifer, Aspergillus niger, and Penicillium italicum. Using berries inoculated with these molds as well as a complex of yeast and bacterial populations similar to microbial conditions found in vineyards, Dr. Thornton and Dr. Rodriguez investigated samples using five spectroscopy approaches to determine the most effective method for analysis: near infrared, visible, ultraviolet, Fourier Transform infrared, and Raman. Near infrared results were inconclusive, and visible and ultraviolet methods weren’t as precise as the results offered by Fourier Transform and Raman. Raman results were aligned significantly with rot content of grapes. However, results also indicated that each vineyard would need to be calibrated for
Dr. Roy Thornton, Ph.D. Professor of Enology the Raman spectra to be conclusive. This being a barrier in terms of cost and time needed to analyze rot in a practical situation, Thornton and Rodriguez have moved forward to analyze samples using Fourier Transform infrared (FTIR) spectroscopy.
Fresno State students analyze samples using five spectroscopy methods
From 2009 to 2011, Thornton and Rodriguez ran 500 Chardonnay and 170 Zinfandel berry samples at a 0- 10% rot content through FTIR analysis. Using the approximately 2000 data points yielded in the spectrum of each sample, a multivariate data analysis method (partial least square regression) was applied to develop a percentage rot prediction model. As data sets grow through addition of samples harvest after harvest, the method’s accuracy also increases. Says Dr. Roy Thornton, “The combination of FTIR spectroscopy and chemometrics offers the best solution in the last 30 years to the problem of quantification of rot in wine grapes.” In 2012, Thornton and Rodriguez took this method to the field.

be transmitted by nematodes (Taylor & Brown, 1997).
The dagger nematode, Xiphinema index (X. index), is considered a major pest in grape growing countries. Grapevines have been moved between countries and continents, following human migration and settlement, and have been imported
Symptoms of Xiphinema index Feeding Xiphinema index feeding initially causes a swollen club -like gall on root tips, which varies in size with the size and vigor of the root (Figure 1). The feeding wound becomes reddish brown to black and forms slightly sunken lesions on the roots (Wyss, 1978). Infested root systems are stunted and have a witchâ€™s broom appearance after successive rounds of new roots branching and being damaged from behind the original damaged root tip (Pearson & Goheen, 1988). Extensive root damage results in reduced shoot growth and yield. Nematode feeding damage induces
and cultivated in numerous countries. These events have increased the incidence and spread of injurious pests and diseases (Esmenjaud & Bouquet, 2009). These pests damage roots, leading to their decay, the prevention of new root development and may result in vine decline and eventual death. (De Klerk & Loubser, 1988). Nematodes associated with vine damage are root-knot nematodes (Meloidogyne spp.), citrus nematodes (Tylenchulus semipenetrans), root-lesion nematodes (Pratylenchus vulnus) and dagger nematodes (Xiphinema spp.) (Nicholas et al., 2007).
Sonet Van Zyl, Ph.D. Professor of Viticulture
Dagger nematodes are considered major pests (Brown et al., 1995), because they are often associated with specific viruses, which they carry from plant to plant through feeding. Dagger nematodes are found in all soil types and more than 92% of all nematodes are found in the 0 to 300 mm zone where most vine roots occur (De Klerk & Loubser, 1988). Light to medium textured soils with a pH between 6.5 and 7.5 seem to be preferred (Siddiqi, 1974). Xiphinema index is even more important as a vineyard pest because of its ability to transmit grapevine fanleaf virus (GFLV). Grapevine fanleaf virus is a member of the nepovirus that have isometric particles of about 28 nm in diameter. One-third of the viruses in this group are known to

water and nutrient stress, which in turn reduces vine vigor and yield. History and Symptoms of Grapevine Fanleaf Virus Grapevine fanleaf virus is one of the oldest viruses of V. vinifera (Pearson & Goheen, 1988) and is still one of the most economically impacting pathogens (Vigne et al., 2005). Vines infected with GFLV are generally seen in patches within a vineyard (Nicholas et al., 2007) and are normally smaller than healthy vines (Golino et al., 1992). In 1954 Hewitt documented the symptoms and the use of indicator plants for GFLV. The impact of GFLV varies with the tolerance of the cultivar and more tolerant cultivars can still produce good crops

(Pearson & Goheen, 1988). The disease is characterized by three distinct symptoms:
Infected leaves exhibit widely open petiolar sinuses and abnormally gathered primary veins causing a fan-like shape (Figure 2a). Bunches are fewer and smaller than usual with shot berries and irregular ripening (Figure 2b) (Pearson & Goheen, 1988). The GFLV can cause up to 80% reduction in fruit set (Nicholas et al., 2007). Affected vines show yellow vein banding along the main veins of mature leaves (Figure 2c) and discolored leaves show little malformation (Pearson & Goheen, 1988).
Fig. 2b. Vines infected with GFLV show smaller, fewer bunches per vine with a high number of shot berries
Management Strategies Each disease and pest requires a different control strategy. Nematodes are primarily spread by the movement of contaminated soil or infested plant material (Nicolas et al., 2007). Preventative measures for controlling X. index and GFLV are usually the best and the most effective way to overcome nematode problems is to use resistant rootstocks. Crop rotation and long fallow periods are not practical for grape growers and soil fumigation are highly restricted due to its toxicity. It is advisable to plant only certified planting stock (Golino, 1993), but studies have shown that even 29

Spring Highlights What’s Been Going On….. This spring has a been a busy one, filled with teaching, research, faculty and staff searches, and outreach activities. In January, many of our faculty, staff, and students travelled to Sacramento to attend the Unified Wine and Grape Symposium. In conjunction with this event, we also hosted our Annual Alumni and Friends Reunion. Thanks again to the Viticulture and Enology Alumni Association (VEAA) for providing financial support for our reunion. We always enjoy the time we get to spend with our alumni and industry friends and feel our presence at the symposium and reunion continues to be productive. The first issue of the Catch Wire newsletter was also a big hit at Unified. The feedback we received on our new look was positive and we look forward to sharing our stories with you in this and future issues.

Keith was a native of Arkansas. In 1988 he relocated to the mid-west before returning to California and Cal Poly San Luis Obispo where he taught viticulture and integrated pest management for many years. Throughout his career, he remained a good friend and industry colleague. In 2012, Keith retired from Cal Poly when his health declined. Keith loved working with students and made many contributions and friends wherever he lived and worked. Fresno State was fortunate to have had him on our viticulture team, even if only for a few years. The grape and wine industry and his students were fortunate to have known him. Keith leaves behind two daughters, and many family members and friends who miss him dearly.
arl Rocca, an alumnus, long-time farmer, and supporter of Fresno State’s viticulture program passed away on March 31, 2013 in Fresno, California. Earl graduated from high school in 1945 before serving as a paratrooper in the Army. He studied viticulture at Fresno State, and graduated with a B.S. degree. He began farming in the Central Valley with his father in 1951. Over the years, Earl became a mechanical raisin harvesting pioneer and a well-respected leader in the raisin industry. Anyone who knew Earl knows that he was a passionate individual who unselfishly gave of his time and energy. His service areas included the Sun-Maid Board of Directors, Fresno-Madera Farm Credit Board, Fresno County Farm Bureau, and Fresno State’s Viticulture Alumni Association. For many years, Earl volunteered as the chairman for the “A Celebration of Wine” fundraising event, helping generate thousands of dollars to support the V. E. Petrucci Library in the Department of Viticulture and Enology. This dedication, leadership, and genuine concern for the viticulture students at Fresno State set him apart from so many. During many field trips to view his mechanical raisin harvester, our students were able to experience his passion for farming and his strong work ethic. His friendship, and his contributions to the university and viticulture program will not be forgotten. He leaves behind his wife of 54 years, Sandy, three sons and their families, his foreman, and many family and friends.
