A Moscow Mule is a cocktail made with spicy ginger blended with lime juice and garnished with a slice or wedge of lime. It is usually served in a copper mug and served with vodka. We omit the vodka and make a yummy probiotic drink instead. If you REALLY like ginger, try using our Lemon Ginger Kombucha for this recipe to add even more of a punch. You can also make this recipe using fermented ginger beer or ginger kefir soda!
