ABSTRACT:
The process comprises bringing into contact a naturally alcoholic beer with a hydrophobic zeolite, separating the aqueous eluent phase from the adsorbent, thermally desorbing the adsorbed products, recovering the desorbed phase and separating it by distillation into an alcoholate and an aromatized phase, then reconstituting an alcohol-free beer by mixing the dealcoholized aqueous phase and the aromatized phase with, secondarily, saturation of the reconstituted beer with gaseous carbon dioxide. The reconstituted beer preserves the organoleptic properties of the initial beer.
