ABSTRACT:
Simultaneous double reverse osmosis process for production of low and non-alcoholic beverages, particularly wines, from any traditionally fermented table wine feedstock. A portion of the feed wine is subjected to remove alcohol and water as a permeate, with recycle of the concentrated retentate, while simultaneously a volume-balanced amount of reverse osmosis water is input back into the feed tank to maintain the in process wine at the initial level of the feedstock wine. The process may be run batch-wise, alternately, or in a modified semi-continuous operation to produce non-alcoholic wines (wines having residual alcohol content of less than 0.01% by volume) low alcohol wires (less than 0.5 volume percent alcohol), or wines having reduced alcohol content (less than 11-13 volume percent). The process also overcomes the 5% alcohol barrier problem of conventional reverse osmosis. The resulting finished wine has flavor, aroma and color solids concentrations of a level acceptable in good commercial practice. Actual non-alcoholic wine produced by the process has won a gold medal in a blind professional taste test.
