From bittermens: "An updated bitter grapefruit aperitif in the Milanese style? A triple sec that’s grapefruit instead of orange? What is this Citron Sauvage? Citron Sauvage is a grapefruit liqueur which we find eminently useful with a capital “U”. Substitute it for Triple Sec in a Margarita for a beautiful pink hued cocktail. Add a dash to a Hemingway to accentuate the bitter grapefruit flavors. Just add a splash of soda for a refreshing spritz or start opening up new variations on a Negroni. We think it’s a little taste of summer in a glass.
The Citron Sauvage is naturally cloudy and may separate during storage. This is normal and does not impact the flavor or shelf stability!
A riff on a classic Tom Collins
1.5 oz Gin (Plymouth works great, as does Beefeater) .5 oz Bittermens Citron Sauvage .25 oz Lemon Juice Soda Water
Build in a Collins glass, add ice and top with soda water. You can add in simple syrup to taste if you prefer a sweeter Collins.
