Portland's own House Spirits approached Portland Syrups 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.
At first, I didn’t like it, but I soon realized that I was going to have to try different flavors with it. I couldn’t use the same ingredients. For instance, I switched bitters on one recipe, and it came alive.
