All beer is created with yeast, but there are filtration processes that can remove yeast from the final product. All domestic beer in the United States such as Budweiser is yeast-free by law.
The two main varieties of yeast used for beer brewing are top-fermenting yeast (Saccharomyces cerevisiae) and bottom-fermenting yeast (Saccharomyces uvarum). The names of both are descriptive of where the fermentation takes place. The top-fermenting yeast is similar to the yeast for baking bread.east is the most important ingredient in beer brewing. It is a single-celled organism; a fungus (phylum Ascomycetes; class Hemiascomycetes; including 10 different families). Yeast is a living creature, metabolizing, reproducing, and living off the ingredients in the beer.
