Portland's own House Spirits approached us to create a tonic that paired with their award-winning Aviation gin. This authentically-brewed whole-ingredient tonic, made with genuine cinchona bark, features a delicate floral layer that supports but does not compete with Aviation's spice roster. Cinchona, the bittering bark from which tonics get their quinine, delivers a complex, gently astringent tonic “bite.” This makes the driest gin and tonic you'll find — simply stir it with a bit of sparkling water prior to building your drink. Each bottle will make approximately 20 cocktails. Ingredients: water, cane sugar, cinchona bark, rosa canina, citric acid. Brewed and bottled in Portland, Oregon. 16 fluid ounces.
