For those who appreciate the sweeter side of gin, take it sloe. A beloved winter liqueur in the U.K., sloe gin is made with sloe berries—cousins of the plum—that are steeped in gin along with sugar. The result is a ruby spirit bottled at a much lower proof than, say, a traditional London dry gin—usually 25% to 30% ABV—with a flavor that’s at once fruity, tart and bitter, depending on the harvest and blend. While the liqueur can be enjoyed neat or on the rocks, the most famous cocktail is, of course, the Sloe Gin Fizz, but it can also be used to remix a Negroni or a martini. Think of it as ginnovation.
