Red Bull Sudachi Lime

Sudachi Lime is a Red Bull flavor built around sudachi, a small, green, sharply acidic citrus from Japan that is eaten more like a lime than an orange. Expect a flavor in that direction: a tart, slightly herbal lime character sitting on top of Red Bull's familiar sweet-tart energy-drink base, rather than the rounder sweetness of a lemon-lime soda. The brief gives no sugar level, carbonation level or ABV, so treat those as unconfirmed and check the can. It is sold here as a mixer and contains no alcohol. Served on its own, it works best well chilled, either straight from the fridge or poured over plenty of ice. Cold temperature keeps the citrus tasting crisp, and as the ice melts a flavored energy drink like this tends to turn sweeter and flatter. A tall glass with large cubes slows that dilution better than small ones. As a mixer, the citrus profile points toward clear spirits. Vodka is the simplest pairing, since it lets the lime come through. Gin adds juniper and botanical notes that suit a green citrus flavor. Blanco tequila and Japanese shochu are also good matches, and a plain light rum would work too. A typical build is one part spirit to three or four parts mixer over ice, finished with a lime wheel or a thin strip of lime peel. A small squeeze of fresh lime will sharpen the drink if the can reads sweeter than you want. Pour gently and stir once to keep the carbonation. For glassware, use a highball or Collins glass. The tall, narrow shape holds the bubbles and leaves room for ice and garnish. For the non-alcoholic serve, a standard tumbler is fine. With food, bright citrus and fizz generally suit salty, fried or spicy dishes. Sushi, yakitori, tempura, fried chicken and spiced noodles are all natural matches.
