USA - Breweries

Anchor Brewing Company is an American alcoholic beverage producer, operating a brewery and distillery on Potrero Hill in San Francisco, California. The brewery was founded in 1896 and was purchased by Frederick Louis Maytag III in 1965, saving it from closure. It moved to its current location in 1979. It is one of the last remaining breweries to produce California common beer, also known as Steam Beer, a trademark owned by the company.

Below are some notes to help identify some of these changes and an aid to reference the year of the glass.
