‘‘ Using this dealcoholisation process, I was pleasantly surprised by the respect for the fruit when we worked on the must. We have produced a true wine. In the liquid phase, the wines are well preserved. And what most impressed us was the quality and flavour of the alcohol produced at the same time. Yes, this is indeed an innovative technology! ’’

SMART WINELYSE, a patented PELLENC innovation developed in collaboration with INREA and IFV, enables targeted alcohol removal both on fermenting musts and finished wines. Integrated into the winemaking process in a flexible and respectful manner, it allows winemakers to adjust the alcohol content at different stages, while preserving the typicity, aromas and quality of the wines.
A major advance in addressing climate issues, consumer expectations, and winemaking expertise.
• Aromatic and taste benefits
• Typicity, colours and aromas preserved
• Does not denature the wine obtained
• No preparation before alcohol removal, nor correction afterwards
• Exogenous inputs not specifically required
• Correct the desired alcohol content with confidence and quality
NEW EXTRACTIONS LINKED TO PARTIAL YEAST LYSIS
Increased liberation of polysaccharides and molecules responsible for the wine’s sensations of fullness and roundness.
Easy completion of alcoholic fermentation, particularly at higher alcohol contents:
• Nutrients from endogenous yeasts retained
• Detoxification of the medium during alcohol fermentation
Positive regeneration of aromatics compounds after dealcoholisation, while alcoholic fermentation continues.
• Native alcohol (45-55°) is very aromatic, fatty, and associated with evaporation at low temperatures
• Alcohol that can be used as ‘wine alcohol’, provided that the production complies with the regulations of the country of production
• Wines that have been dealcoholised using this process are eligible for organic certification
*production and storage of alcohol is subject to local legislation and declarations with which the producer must comply
100% AUTOMATIC
• 0 consumables, 0 wine preparation, Smart control
• Simple automation: the operator enters initial titration, target titration and volume to process
• Real-time display: volumes extracted, progression
• Fast, automated wash cycle
• Connected: monitoring via PELLENC Connect
• Compact and mobile module
The fermenting must is moderately heated and continuously fed into the high-vacuum tank, where the water/ethanol mixture evaporates instantaneously. The condensate with an alcoholic strength of between 45-55% vol is extracted, and the alcoholic strength is lowered by 2 to 5% vol. Only part of the tank is processed, depending on the objective, and then reintroduced into the initial tank to complete fermentation.
On finished wine, the technology allows a reduction of up to 6% by volume in a single pass, without destroying the aroma or flavour.
The process is based on partial vacuum evaporation, a technique that significantly lowers the boiling temperature of volatile compounds. A wine containing 10% ethanol will boil at 20°C under an absolute pressure of 30 hPa.
This low-temperature operation not only significantly reduces energy consumption, but also preserves the organoleptic qualities of the product.
The vacuum evaporation system is optimised to reduce energy consumption to a minimum (COP=5.0). The reversible heat pump simultaneously generates: the hot water to heat the product to a temperature sufficient for evaporation, the cold water needed for the condenser, which liquefies the water/ethanol mixture and reduces the alcohol content of the treated product.
• Heat pump energy efficiency COP 5.0: with a power consumption of 18.5 kW, generation of up to 40 kW for cooling and 55 kW for heating
• 3.0 kW vacuum screw pump
• Suitable for
