Fever Tree makes all-natural, premium mixers--most famously tonic waters and this ginger ale--that have taken the cocktail world by storm. The New York Times called them, "A mixer to take seriously," and their products definitely enhance the drinks they go into. The ginger ale is my personal favorite, brimming with the spicy quality of the famous root. Mix with gin and a squeeze of lime for a "Mother's Little Helper," my cocktail of choice these days.
