Ginger beer: Ginger beer is a carbonated beverage that is made from ginger, sugar, and water. It has a strong, spicy flavor with a hint of sweetness. The ginger flavor is often intense and can be described as a combination of ginger spice and ginger root. The sweetness in ginger beer varies depending on the brand, but it is generally not as sweet as traditional soda. The carbonation adds a slight effervescence to the drink, making it a popular mixer in cocktails. Some ginger beers might have a slight hint of citrus, and some other spices like cinnamon, nutmeg, and allspice. When used in cocktails, ginger beer adds a unique, spicy kick to the drink, and can balance out the sweetness of other ingredients. The carbonation also adds a refreshing quality to the drink. When used in a Dark 'n' Stormy or Moscow Mule, the ginger beer helps to complement the flavors of the rum or vodka and lime juice. When used in a Gin-Gin Mule or Penicillin, it helps to balance the flavors of gin and honey.
Vodka: Vodka is a clear distilled alcoholic beverage. Different varieties originated in Poland, Russia, and Sweden. Vodka is composed mainly of water and ethanol but sometimes with traces of impurities and flavorings. Traditionally, it is made by distilling liquid from fermented cereal grains. Potatoes have been used in more recent times, and some modern brands use fruits, honey, or maple sap as the base. Since the 1890s, standard vodkas have been 40% alcohol by volume (ABV) (80 U.S. proof). The European Union has established a minimum alcohol content of 37.5% for vodka. Vodka in the United States must have a minimum alcohol content of 40%.
