What fungi are used to ferment wine beer and vinegar?

Here's a breakdown of the fungi involved in fermenting wine, beer, and vinegar:

Wine:

* Yeast: *Saccharomyces cerevisiae* is the primary yeast used for wine fermentation. It converts sugars in grapes into alcohol and carbon dioxide. Other yeast species may also play a role, contributing to unique flavors and aromas.

Beer:

* Yeast: *Saccharomyces cerevisiae* is also the primary yeast used for beer. Different strains of *S. cerevisiae* are selected for different beer styles (ale vs. lager), affecting flavor, aroma, and alcohol content.

Vinegar:

* Bacteria: Acetic acid bacteria (AAB), primarily *Acetobacter pasteurianus*, are responsible for converting ethanol (alcohol) into acetic acid, which is the main component of vinegar.

Important Notes:

* Wild Yeasts: Wine and beer can also be fermented using "wild yeasts" (non-cultivated strains) found naturally on grapes or other raw materials. This often results in more complex and unpredictable flavors.

* Bacteria in Wine: While primarily a yeast process, some bacteria play a role in winemaking, contributing to malolactic fermentation, which converts malic acid into lactic acid, reducing acidity and adding complexity.

* Other Fungi: While yeast and bacteria are the key players, other fungi may be present in these processes, though their impact is generally less significant.
