Dealcoholization
Dealcoholization is a process in which alcohol is removed from a product or beverage in order to obtain an alcohol-free or alcohol-reduced variant.
Taste retention during beer and wine dealcoholization
Beer/wine dealcoholization with the De-Alconox (thermal dealcoholization) is a gentle process in which the alcohol content in the beer is greatly reduced without affecting the quality of the beverage. Our dealcoholization systems are designed to process both filtered and unfiltered beer at low temperatures of below 39°C in order to optimally preserve the taste. The alcohol content is reduced to <0.02% vol. and the alcohol removed can be rectified to 80% vol. Thanks to the flexible design, we can easily process different product flows and compositions. This makes our systems a sustainable investment that supports breweries/wineries in responding flexibly to current and future market trends and efficiently meeting the growing demand for non-alcoholic beverages.
- Thermal dealcoholization of beer, must and wine (including sparkling wine)
- Processing at particularly low temperatures below 39°C
- Reduction of the alcohol content to below 0.02% vol.
- Suitable for both filtered and unfiltered beverages

Beverage dealcoholization in a vacuum/falling film evaporator?- We work continuously, in-line
In the design and operation of our dealcoholization systems, particular emphasis is placed on gentle processes in order to maintain optimum beer quality. First, the beer is gently degassed to prevent foaming throughout the process. This takes place in a special degassing system that achieves very low final gas values (≤ 0.1 g CO2/l) - without any recirculation. The foam stability in the end product remains unchanged. The incoming beer is heated in counterflow to the dealcoholized beer (the outgoing beer is cooled as a result), which enables efficient use of energy.
The actual alcohol removal takes place in a special column consisting of two sections: The first section is used to expel the alcohol from the beer, while in the second section the alcohol is rectified to the desired concentration. Thanks to high-precision internals in the column, the pressure drop is minimal, which enables a low temperature in the column sump and thus protects the beer quality and reduces energy consumption.
The energy for the process is provided by a small amount of live steam. This is used to evaporate vapors from the product, which can strip the alcohol content in the product to less than 0.02 % vol. Large heat transfer surfaces in the evaporator minimize the surface temperature in contact with the product. The entire process takes place under vacuum, which keeps the product temperature below 39°C and ensures excellent beer quality. Finally, the beer is cooled and carbonated to obtain a high-quality dealcoholized end product. Our standardized dealcoholization systems are also suitable for unfiltered products and are available in capacities from 15 to 200 hl/h.

Carbonization
The batch carbonator is used for efficient carbonation or nitrogenation as well as for cooling smaller product quantities in off-line operation. With the Bucher Denwel injector, CO₂ or N₂ is introduced into the product during the circulation process, while the pressure and temperature in the tank remain constant.
Kieselguhr/Stabilizer
The CO₂ inlet, which is aligned with the agitator blades, maximizes deaeration efficiency and minimizes gas consumption. Bucher Denwel's axial agitator ensures rapid homogenization and energy savings by adjusting the agitation speed.
Reconnection lantern
The deaeration lantern efficiently removes air from the beer flow and discharges it through a pneumatic valve. When a tank is emptied, the beer flow is automatically reduced and the lantern switches seamlessly to the next full tank to minimize air intake.
