Gentle alcohol removal with maximum flavor retention

Bucher Denwel offers advanced beer dealcoholization solutions based on membrane and thermal technologies, designed to meet the highest quality standards in industrial and craft brewing. Both approaches allow brewers to produce beers with alcohol contents below 0.5% vol. or even <0.03 % vol. Unlike traditional high‑temperature processes, Bucher Denwel dealcoholization systems operate at very low process temperatures and in closed, oxygen‑free systems, preventing oxidation, aroma loss, and heat‑related off‑flavors. This ensures that the dealcoholized beer retains its original mouthfeel, freshness, and aroma profile.

Membrane dealcoholization – De‑Alconox M

The De‑Alconox M system uses pressure‑driven membrane separation to selectively remove alcohol and water from beer. Thanks to low operating temperatures (below 10 °C) and carefully selected membrane pore sizes, valuable aroma compounds remain in the product.

This technology is ideal for breweries seeking a highly gentle and energy‑efficient solution, particularly for premium non‑alcoholic beers.

Thermal dealcoholization – De‑Alconox B

For maximum flexibility, Bucher Denwel also offers thermal dealcoholization with the De‑Alconox B system. Operating under vacuum and at temperatures below 39 °C, this process gently removes alcohol while minimizing thermal stress on the beer. The system’s innovative column design ensures efficient alcohol separation with highest flexibility even for unfiltrated beers, making it a future‑proof investment for evolving market demands.
 

Tailored solutions for modern breweries

Whether membrane‑based or thermal, Bucher Denwel beer dealcoholization solutions are designed as integrated, turnkey systems, from process design and automation to installation and commissioning. Each solution can be customized to fit existing brewery layouts, production volumes, and product portfolios.
