What is made wine?
Yeast does not make wine, it just allows for the growth and creation of yeasts that can continue to get yeasts from the environment and still function. Vat or yeast at work.
The most common form of wine made from yeast is white wine, which is only made of grape juice. Vodka is made from grain alcohol. Sour, fruit-based wines are made from fermentation. Wine made from sweet, fermented beverages is also made from yeast. Vegetable-based wines are made from the fermentation of sugar and starch. Sour-or-sweet-dew, if you will.
