I used Empress 1908 Gin for this cocktail which has such a lovely unique flavor and honestly is one of my favorite gin brands. Other brands that I've tried and like include Tanqueray (which I used in my Pear Gin Fizz) and Malfy Gin (which is my go-to for a basic Gin & Tonic). With Gin, I always recommend trying the brand first to make sure you like it. Because of the different botanicals in each Gin, the flavor can really vary a lot between brands.
