Vine-Glo was a grape concentrate brick product sold in the United States during Prohibition by Fruit Industries Ltd, a front for the California Vineyardist Association (CVA), from 1929. It was sold as a grape concentrate to make grape juice from but it apophatically included a warning with instructions on how to make wine from it. [1]
A sour-tasting, highly acidic, liquid made from the oxidation of ethanol in wine, cider, beer, fermented fruit juice, or nearly any other liquid containing alcohol. Viniculture The art and science of making wine. Also called enology (or oenology). Not to be confused with viticulture. Vinification The process of making grape juice into wine. Vin ...
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
In Germany fruit dessert wines are fruit wines with more than 12.0% vol. In Austria they need an alcohol content of at least 13.0% vol. to a maximum of 22.0% vol. The total alcohol content may be increased by adding alcohol, fruit spirits, sugar, fruit juice and fruit juice concentrate to the fruit wine or cider.
Straw wine, or raisin wine, is a wine made from grapes that have been dried off the vine to concentrate their juice. Under the classic method, after a careful hand harvest, selected bunches of ripe grapes will be laid out on mats in full sun.
It is the product of fermented freshly pressed grape juice, known as must. The term Federweisser in principle includes all stages of fermentation, from must to finished wine. It is typically 9% alcohol by volume, although versions of up to 13.5% alcohol by volume are not uncommon.
The decision about destemming is different for red and white wine making. Generally when making white wine the fruit is only crushed, the stems are then placed in the press with the berries. The presence of stems in the mix facilitates pressing by allowing juice to flow past flattened skins. These accumulate at the edge of the press.
In many wine regions, brown sugar is an illegal additive, and in regions that disallow chaptalization altogether, grape concentrate may be added. [3] After sugar is added to the must, naturally occurring enzymes break down the sucrose molecules in sugar into glucose and fructose , which are then fermented by the yeast and converted into alcohol ...
