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.
Grape stomping at the Colorado Mountain Winefest in Grand Junction, Colorado, United States First developed in the Middle Ages, basket presses have a long history of use in winemaking. The earliest wine press was likely the human foot or hand, crushing and squeezing grapes into a bag or container where the contents would ferment.
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 first wine press was probably the human foot and the use of manual treading of grapes is a tradition that has lasted for thousands of years and is still used in some wine regions today. The history of the wine press and of pressing is nearly as old as the history of wine itself with the remains of wine presses providing some of the longest ...
The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds. Vines store sugar in grapes through photosynthesis, and acids break down as grapes ripen. Secondary compounds are also stored in the ...
A place where grape vines are grown for wine making purposes. Vintage The year in which a particular wine's grapes were harvested. When a vintage year is indicated on a label, it signifies that all the grapes used to make the wine in the bottle were harvested in that year. Viticulture The cultivation of grapes. Not to be confused with viniculture.
Grapes ripening on the vine. In viticulture, ripeness is the completion of the ripening process of wine grapes on the vine which signals the beginning of harvest.What exactly constitutes ripeness will vary depending on what style of wine is being produced (sparkling, still, fortified, rosé, dessert wine, etc.) and what the winemaker and viticulturist personally believe constitutes ripeness.
The history of viticulture is closely related to the history of wine, with evidence that humans cultivated wild grapes to make wine as far back as the Neolithic period. Evidence suggests that some of the earliest domestication of Vitis vinifera occurred in the area of the modern countries Georgia and Armenia. [6]
