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.
Wine grapes from the Guadalupe Valley in Ensenada, Baja California, Mexico. Winemaking, wine-making, or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia.

The most common ritual was to pour the liquid from an oinochoē (wine jug) into a phiale, a shallow bowl designed for the purpose. After wine was poured from the phiale, the remainder of the oinochoē's contents was drunk by the ...
In surface filtration, the wine passes through a thin membrane. Running the wine parallel to the filter surface, known as cross-flow filtration, will minimize the filter clogging. The finest surface filtration, microfiltration, can sterilize the wine by trapping all yeast and, optionally, bacteria, and so is often done immediately prior to ...
The wine offers crisp acidity, clipped stone minerality, and refreshing, textured tannins. It finishes with a lift of quince and great length. 2021 Limited Addition Gamay Noir, Willamette Valley ...
The primary role of yeast is to convert the sugars present (namely glucose) in the grape must into alcohol.The yeast accomplishes this by utilizing glucose through a series of metabolic pathways that, in the presence of oxygen, produces not only large amounts of energy for the cell but also many different intermediates that the cell needs to function.
