Amazon is one source that sells different brands of ginger beer in single bottles or in packs of four to eight. Ginger beer is different than ginger ale, and the name is misleading because ginger beer is non-alcoholic.
Originally, ginger beer was an alcoholic beverage of water, sugar, ginger and a fermented culture of the ginger beer plant. The beverage was popular in the 18th century, but is now used as a soft drink or as an ingredient in mixed drinks.
Unlike ginger ale, ginger beer has a zesty flavor with added spice. People enjoy drinking ginger beer in place of ginger ale or using it as the main ingredient in a cocktail.
