Falstaff: an unpasteurized beer made in several places in the United States (e.g. New Orleans).

Sale and consumption are outlawed in several other states (e.g. Tennessee) due to the unpasteurized nature of this peculiar brew.

Pasteurization is, of course, the process by which germs (so called "spoilage organisms") are killed in such products as milk, wine, and beer. There are two primary uses for pasteurization: public health and product quality. Pasteurization removes many harmful bacteria and increases "shelf life."

Fermented beverages that are not pasteurized are therefore not allowed for sale in many states in the U.S. in the interests of public safety.
