The Gin & Tonic is undoubtedly one of the most popular cocktails in the world, that's why we celebrate it on National Gin & Tonic day on April 9th! It’s the go-to cocktail in Spain, where a particular gin’s botanicals are paired specifically with tonic water and an array of aromatic garnishes, the resulting creation generally served in a goblet. It’s an at-home staple in the U.K., where the number of craft tonic waters on the market are virtually endless, as are craft gins that have boomed concurrently. It’s also a summer staple for many Americans, who generally just keep it simple with whatever gin and tonic water is available at the local grocery store, but bartenders have begun to elevate the refreshing classic with higher-end tonic waters, selected to complement the gin used.
