Abstract
Abstract In processes for making wine and beer the off-gases from the fermentation process are passed through activated carbon filters. The carbon is later on desorbed by mixing it into a small volume of the product wine or beer. This enriched volume is then used to enhance the flavour and aroma of a larger volume of wine or beer by suitable blending.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A METHOD OF UPGRADING A BEVERAGE PRODUCED BY A FERMENTATION PROCESS FORM A BASE MATERIAL INCLUDING THE STEPS OF: A. FERMENTING THE BASE MATERIAL TO PRODUCE AN ALCOHOLIC BEVERAGE, AND OFF-GASES RESULTING FROM THE GERMENTATION PROCESS CONTAINING HYDROGEN SULPHIDE AND FLAVORURING AND AROMA SUBSTANCES, B. PASSING THE OFF-GASES THROUGH A LAER OF MATERIAL SELECTED FROM THE GROUP CONSISTING OF ACTIVATED CARBON, COPPER METAL PARTICLES AND COPPER OXIDE, THAT ABSORBS HYDROGEN SULPHIDE TO PURIFY THE GASES, C. PASSING THE PURIFIED GASES THROUGH A BED OF ACTIVATED CARBON TO LOAD THE CARBON WITH FLAVOURING AND AROMA SUBSTANCES, D. DESORBING THE FLAVOURING AND AROMA SUBSTNCES ON THE CARBON, AND E. ADDING SOME OF THE DESORBED FLAVOURING AND AROMA SUBSTANCES TO THE BEVERAGE.

Claim 3
Dependent Claim
22 words
The method claimed in claim 1 in which the flavouring and aroma substances are desorbed with a small amount of the beverage.
Claim 4
Dependent Claim
17 words
The method claimed in claim 1 in which the flavouring and aroma substances are desorbed with ethanol.
Claim 5
Independent Claim
109 words
A method of producing wine from a must including the steps of: a. fermenting the must to produce wine and off-gases containing hydrogen sulphide and flavouring and aroma substances, b. passing the off-gases through a layer of a material selected from the group consisting of activated carbon, copper metal particles and copper oxide, that absorbs hydrogen sulphide to purify the gases, C. passing the purified gases through a bed of activated carbon to load the carbon with flavouring and aroma substances, d. desorbing the flavouring and aroma substances on the carbon, and e. adding some of the desorbed flavouring and aroma substances to wine to produce a product wine.
