Let's discuss the winemaking process:
Grapes are harvested, crushed, and fermented in vats or buckets. During the fermentation process, the sugars in grape juice are converted to alcohol. Fermentation may happen spontaneously, although winemakers occasionally use yeast to aid in the process.
The peels and other debris are removed from the mashed grapes by pressing them. The wine's color depends on whether this procedure is performed after or before fermentation and the grape color.
Grapes are squeezed before fermentation to create white wine. Red wine is typically squeezed after fermentation.
The wine is next matured in oak barrels or stainless steel until it is ready to be bottled.
