Whiskey and ginger beer are a natural pairing. Whiskey provides a basic sweetness that cuts through the spiciness of good ginger beer. The Irish Ale Cocktail is a variation of two common cocktails, the whiskey & ginger and the Moscow Mule. Adding a few squeezes of lime provides just enough acid to help marry the sweet and spicy notes in this cocktail. If you don't like the spiciness of ginger beer, you can make this cocktail milder by substituting ginger ale. Try this one at home or on your next evening out.
