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.
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]
Orange wine (a.k.a. skin-contact white wine) is wine made with maceration in the manner of rosé or red wine production, but using white wine grape varieties instead of red. To start primary fermentation, yeast may be added to the must for red wine, or may occur naturally as ambient yeast on the grapes (or in the air).
Grape-treading or grape-stomping is part of the method of maceration used in traditional wine-making. [ 1 ] [ 2 ] [ 3 ] Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation .
The "cap" of grape skins being "punched down" to maximize maceration. The process of maceration begins, to varying extent, as soon as the grapes' skins are broken and exposed to some degree of heat. Temperature is the guiding force, with higher temperatures encouraging more breakdown and extraction of phenols from the skins and other grape ...
Another advancement was the complete enclosure of the press (sometimes called "tank press") that reduced the exposure of the grape must to air. Some advance presses can even be flushed with nitrogen to create a complete anaerobic environment that can be desired for wine making with white wine grapes. Additionally, many of today's modern presses ...

Muscat grapes drying in the sun Grapes sun-wilting on the plant Grapes laid out to dry. 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.
