METHOD

Dealcoholization

InnoSolv ltd. develops and offers its own innovative dealcoholization method designed for the dealcoholization of wine. This new procedure uses low temperature nitrogen gas assisted distillation to ensure a gentle removal of the ethyl alcohol for a quality and enjoyable end product.

Separated outlet distillate can be kept for spirit usage or automatically diluted with water to an alcoholic strength below no tax excisable limits.

Main method strengts:

Gentle, mild wine treatment
Wine process temperatures 25 – 28^oC – no thermal destructions
Short wine residence times – single pass work
Nitrogen process blanket during treatment – no oxidation
Compatibility with Resolution OIV-OENO 394A-2012 for non-alcoholic wines
Retains in product all non-volatile compounds and maximum non-volatile compounds
Option for keeping distillate alcohol content high – two products outlet
No pressures, vacuum, steam boilers, etc.
Low process temperatures allow heat pumping and green process

Wine changes during dealcoholization:

Reducing volume – up to 55% compared to inlet
Increasing total dry matter content – more dense taste
Increasing total acids content – more sour taste
Total sulfur degassing

These changes may imply post-processing adjustments to the outlet composition in order to achieve a desired organoleptic profile. The corrections are minimal when the goal is to lower the natural alcohol content and more substantial when the goal is to obtain a non-alcoholic wine. Post-processing may includes deacidification, filtration, sulfitation, water restoring, etc. to achieve the desired organoleptic characteristics and anti-microbial stability.
