Gin: Gin is a distilled alcoholic drink that derives its predominant flavour from juniper berries (Juniperus communis). Gin originated as a medicinal liquor made by monks and alchemists across Europe, particularly in southern France, Flanders and the Netherlands, to provide aqua vita from distillates of grapes and grains. It then became an object of commerce in the spirits industry. Gin emerged in England after the introduction of jenever, a Dutch and Belgian liquor that was originally a medicine. Although this development had been taking place since the early 17th century, gin became widespread after the William of Orange–led 1688 Glorious Revolution and subsequent import restrictions on French brandy.
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.
