PCT No. PCT/FR82/00005 Sec. 371 Date Sep. 13, 1982 Sec. 102(e) Date Sep. 13, 1982 PCT Filed Jan. 13, 1982 PCT Pub. No. WO82/02405 PCT Pub. Date Jul. 22, 1982.The method consists in subjecting a natural alcoholic liquid to three successive steps of non denaturating physical fractionation; the first step is a molecular utltrafiltration under low pressure through a semi-permeable ultra-filter the splitting threshold of which is between 30,000 and 1000 and preferably around 10,000; the second step is a reverse osmosis step applied to the ultra-filtrate resulting from the preceding operation through semi-permeable membranes the splitting threshold of which is between 500 and 100 and preferably around 250; the third step consists in evaporating and distillating under vacuum, at low temperature, the ultra-filtrate resulting from the second step. Natural beverages having a low alcohol content thus obtained. Products obtained from the filtrates or retention products of the various steps of the method.
