Dealcoholization without compromise - aroma-preserving, efficient, flexible.
DeAlcoTec removes alcohol from wine and beer at low temperature and low pressure. The result: a nearly alcohol-free product with maximum aroma retention - fully automated and designed for controlled intervention in a highly sensitive product.
Alcohol < 0.01 vol.% - 100% flavor.
Gentle technology for reproducible results
Our dealcoholization system is designed to preserve aroma, taste and product quality while removing alcohol under controlled, reproducible process conditions. In wine applications, the key factor is not alcohol removal alone, but controlled intervention in a highly sensitive product matrix. This makes DeAlcoTec relevant not only for alcohol-free products, but also for targeted alcohol adjustment and the development of new low- and no-alcohol concepts in wine.
Preheating & regenerative plate heat exchanger
The incoming alcohol-containing product is gently preheated in countercurrent flow to the finished alcohol-free product.
Deaeration for CO₂-containing beverages
Pre-process to prevent foam formation.
Evaporation column & falling film evaporator
The product flows downward from the top while alcohol-diluted vapors rise from below - interaction under vacuum removes the alcohol. The less volatile components remain.
Aroma recovery
Volatile aromas that escape with the vapors are separated and returned to the product.
Optional: Alcohol rectification & utilization
The alcohol can be concentrated up to approx. 90 vol.%, for example for other applications or for economical utilization.
Wine-specific value
In winemaking, the focus is particularly on controlled alcohol adjustment - for example to adjust balance, style and market requirements.

Dealcoholization of wine
Targeted control of alcohol content in wine is becoming increasingly important. Alongside the production of alcohol-free wines, the focus is increasingly on targeted alcohol adjustment within the existing portfolio - for example, to align balance, style and market requirements under reproducible process conditions. In wine, this requires controlled intervention in a highly sensitive product matrix.
Typical wine applications
-
Reduction of excessive alcohol content
-
Production of alcohol-free wines
-
Development of new low- and no-alcohol products
-
Adjustment of style and balance
The central challenge
The real difficulty lies not only in removing the alcohol itself, but in handling aroma-relevant components at the same time. What matters is therefore not only the process itself, but controlled intervention under reproducible process conditions, including aroma management and measurement.
Vacuum rectification vs. membrane process
Why DeAlcoTec is the better choice for aroma-preserving dealcoholization. For project design, it is not only the process technology that matters, but the overall assessment of product quality, operation, alcohol concentrate and aroma recovery.
Criterion:
Residual alcohol

What makes DeAlcoTec distinct
✅ Aroma retention through gentle processes at low temperature and pressure
✅ Residual alcohol levels close to the detection limit
✅ Modular design & skid mounting, easy installation
✅ Hygienic design & fully CIP-capable
✅ Optional rectification & recovery of alcohol plus aroma recovery
✅ Precise process sensing and control for consistent quality & efficiency
Added value & return with DeAlcoTec
An investment in dealcoholization is not limited to alcohol removal. It also opens new market segments, enables premium products and supports the optimization of energy and production costs. In wine, DeAlcoTec is relevant not only for 0.0 applications, but also for targeted alcohol adjustment in existing products and for new alcohol-free premium and aperitif concepts.
