Abstract
Abstract An alcoholic liquid obtained by fermenting a must or a wort is initially subjected to ultrafiltration or to reverse osmosis to obtain a permeate which contains a higher proportion of water and alcohol than the starting liquid and a concentrate which contains a higher proportion of the substances that flavor the starting liquid. The permeate is then subjected to reverse osmosis using a membrane which is substantially impermeable to alcohol, while still being permeable to water. The concentrate from the second step is added to the concentrate from the first step to produce a liquid which has a higher concentration of alcohol than the starting liquid. The resulting liquid may be useable at said higher concentration as a beverage, or it may be used for transport and/or for storage, with water being added to thereto to restore the beverage substantially to its starting condition before being drunk.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A method of processing an alcoholic starting liquid which has been obtained by fermenting a must or a wort, wherein said alcoholic starting liquid is subjected to a first processing step consisting in ultrafiltration or reverse osmosis giving a concentrate and a permeate, the improvement wherein said permeate is further subjected to a second processing step consisting in reverse osmosis using a membrane which is substantially impermeable to alcohol, the concentrate from said second processing step added to the concentrate obtained from said first processing step to provide a liquid having a higher degree of alcohol than the starting liquid and wherein the said obtained liquid with the higher degree of alcohol is further subjected to another cycle of said first and second processing steps, the concentrate from said second processing step added to the concentrate from said first processing step to yield a liquid with a further increased alcohol content.
Claim 2
Independent Claim
151 words
A method of processing an alcoholic starting liquid which has been obtained by fermenting a must or a wort, wherein said alcoholic starting liquid is subjected to a first processing step consisting in ultrafiltration or reverse osmosis giving a concentrate and a permeate, the improvement wherein said permeate is further subjected to a second processing step consisting in reverse osmosis using a membrane which is substantially impermeable to alcohol, the concentrate from said second processing step added to the concentrate obtained from said first processing step to provide a liquid having a higher degree of alcohol than the starting liquid and wherein the said obtained liquid with the higher degree of alcohol is further subjected to another cycle of said first and second processing steps, the concentrate from said second processing step added to the concentrate from said first processing step to yield a liquid with a further increased alcohol content.
Claim 3
Dependent Claim
11 words
An alcoholic liquid obtained by performing the method of claim 1.
Claim 4
Dependent Claim
11 words
A beverage obtained by deionizing the alcoholic liquid of claim 2.
Claim 5
Independent Claim
75 words
A method of manufacturing an alcoholic liquid, wherein the method comprises the steps of: taking a must or a wort containing fermentable sugars; fermenting said must or wort; subjecting the resulting alcoholic liquid to ultrafiltration to obtain a concentrate and a permeate; subjecting the permeate from said ultrafiltration to reverse osmosis using a membrane that passes substantially only water; and adding the concentrate obtained from the reverse osmosis to the concentrate obtained from the ultrafiltration.
Claim 6
Independent Claim
75 words
A method of manufacturing an alcoholic liquid, wherein the method comprises the steps of: taking a must or a wort containing fermentable sugars; fermenting said must or wort; subjecting the resulting alcoholic liquid to ultrafiltration to obtain a concentrate and a permeate; subjecting the permeate from said ultrafiltration to reverse osmosis using a membrane that passes substantially only water; and adding the concentrate obtained from the reverse osmosis to the concentrate obtained from the ultrafiltration.
Claim 7
Dependent Claim
43 words
A method according to claim 4, wherein said ultrafiltration step is replaced by a reverse osmosis step using a membrane that passes both water and alcohol but which retains the bulk of products that determine the taste and the odour of the liquid.
Claim 8
Dependent Claim
26 words
A method according to claim 4, wherein amylo-glucosidase is added to the initial must or wort before fermentation to improve the fermentability of the sugars therein.
Claim 9
Dependent Claim
15 words
An alcoholic liquid obtained by performing the method according to claims 4, 5 or 6.
Claim 10
Dependent Claim
60 words
A method accordng to claim 4, comprising the additional steps of: subjecting the mixture of the two concentrates to ultra-filtration to obtain a concentrate and a permeate; subjecting the permeate from said ultra-filtration to reverse osmosis using a membrane that passes substantially only water; and adding the concentrate obtained from the reverse osmosis to the concentrate obtained from the ultra-filtration.
Claim 11
Dependent Claim
12 words
An alcoholic liquid obtained by performing the method according to claim 8.
Claim 12
Dependent Claim
9 words
A beverage according to claim 9 which is deionized.
