PCT No. PCT/CH86/00178 Sec. 371 Date Sep. 28, 1987 Sec. 102(e) Date Sep. 28, 1987 PCT Filed Dec. 18, 1986 PCT Pub. No. WO87/03902 PCT Pub. Date Jul. 2, 1987.A method to dealcoholize partially or totally wine and/or cider and apparatus to implement this method. The invention aims to permit a partial or total dealcoholization of wine and/or of cider while preserving the bouquet and the aroma of the treated product. The apparatus used comprises a vat containing the liquid to be treated, a module of reverse osmosis, and a closed circuit between these two elements to cause the liquid that is to be treated to circulate through the module and return to the tank. Mounted in this circuit are a high pressure pump and means to control and regulate the pressure, the temperature and the flow to enable the dealcoholization operation to be effected. Means are provided to inject demineralized, dechlorinated water to make up for the loss of permeate. An ingredient container is provided to mix ingredients tending to give the original bouquet and aroma back to the treated liquid. The invention is applicable to all liquids containing alcohol, particularly wine.
