What is "ginger beer"?

Ginger beer is a non-alcoholic carbonated drink that is made from ginger, sugar, water, and sometimes other flavorings such as lemon or lime juice. It has a spicy, sweet, and slightly tangy taste that is different from ginger ale, which is a similar but milder version of the beverage. Ginger beer is made by fermenting a mixture of ginger, sugar, and water with a culture of yeast and bacteria, which can produce a small amount of alcohol, typically less than 0.5%. The fermentation process can take several days or longer, depending on the desired level of carbonation and flavor. Ginger beer can be enjoyed on its own as a refreshing beverage, or used as a mixer for cocktails such as Moscow Mules or Dark and Stormys. It is also sometimes used in cooking or as a marinade for meats, particularly in Caribbean cuisine.
