Enzyme Solutions - Fermentation Aids
Fermentation Aids Sluggish or stuck ferments remain a major concern for winemakers during any vintage. Ensuring good hydration of budding yeast and adequate nutrition of fermenting yeast are some of the most critical steps in ensuring a healthy fermentation. Budding and fermenting yeast differ in their nutrition requirements.
METHOD Addition: Make a slurry of the product by dissolving the product in water or fermenting juice. Add the slurry slowly to the fermentation tank as the presence of solids could cause foaming. Timing: Ferm Boost – add at the begining offermentation at the yeast hydration stage.
Budding yeasts The cell walls of budding yeast are highly permeable and hence readily ingest any nutrients provided at the hydration stage.
Ferm Assist and Ferm Classic – add on second or third day of fermentation at approximately 1-2 Baumé drop.
Fermenting yeast These show lower nutrient ingestion capabilities, especially towards the later stages of fermentation. An appropriate supply of micro and macro nutrients including nitrogen and carbon sources, vitamins and inorganic minerals provided at the right growth stage can thus ensure strong yeast growth and complete fermentations.
Ferm Assist •
Ferm Boost
A unique blend of a high efficiency protease combined with yeast nutrients to help ferments continue to completion. The protease breaks down complex proteins into amino acids and peptides, thereby providing multiple sources of YAN for the growing yeast to assimilate and use during the later alcohol stressed stages of fermentation, when the capacity to ingest external nutrients is low. By ensuring nutrient availability at such critical stages in the fermentation, Ferm Assist allows the yeast metabolism to continue towards a smoother and complete ferment.

Designed for budding yeast, this blend of inactivated yeast has been specially formulated to meet the nutritional requirement of the growing yeast. While the yeast sacs and hulls provide a rich source of vitamins and amino acids, glutathione protects the young yeast cells from being killed through osmotic shock. Together, this results in a healthy yeast hydration and a rapid increase in yeast numbers.
