You cannot make wine without yeast of some form. Yeast is necessary to convert the sugars in fruit juice into alcohol. Without yeast, alcohol production is not possible. Even the colloquial form of winemaking that takes place in institutions of incarceration utilizes naturally occurring yeast, or may be rudimentarily "jump-started" using bread yeast.
Fermentation can take place when making wine without yeast. As when the grapes used to make the wine are crushed, the skins of the grape release yeast, as they already contain it, ready to mix with the sugar from the juice of the actual grape. :)

you dont use yeast to make wine.
yeast
The bacteria that is used in winemaking is called 'yeast' or 'wine yeast'. Yeast are not bacteria. Yeast are used to ferment juice and make wine. The traditional yeast is Saccharomyces cerevisiae. Bacteria is also used for the malolactic fermentation of red wines and some whites. This is a decarboxylation of malic acid to lactic acid. The bacteria used is Oenococcus oeni.
Yes they did
yeast
Saccharicmeces Cervaeces, Known to you and I as Yeast is the primary microbe used in the making of alcoholic beverages. It is the same yeast (Although a different strain) as what is used in the breadmaking process.
yes
Yes and no it depends on what your baking. For example if your baking a cake with wine yeast then no. Now you can dry the wine yeast to get out the flavor, but it still tstes like wine.
By converting sugar into alcohol and carbon dioxide.
Fermentation of sugars to produce alcohol does require the presence of yeast, however, its not always necessary to add the yeast. For example, crushed grapes will start fermenting without addition of yeast because the skins contain natural wild yeast cells that will ferment. However, in order to make good wine, the grapes are usually sterilized and cultured yeasts developed especially for wine are added.
