Ingredients: Champagne or sparkling wine, sugar cube, bitters
Backstory: The Champagne Cocktail dates all the way back to legendary barman Jerry Thomas. In his 1862 book How to Mix Drinks: Bon Vivant’s Companion, the “Professor” sets forth the standard recipe for a sparkling wine cocktail which still lives on to this day. Back in Thomas’s day it was known as “Chorus Girl's Milk,” and it remains one of the few “famous” Champagne cocktails.
Why it’s a classic: “It's first truly sophisticated classic cocktail, giving you the strength of brandy with the effervescent, classiness of champagne. Still the go-to cocktail at any dinner party.”—Laboy
3 oz Champagne ⅓ oz Cognac 2 dashes Angostura bitters 1 sugar cube
Add 2 dashes of Angostura bitter and sugar cube into a Champagne flute. Add cognac followed by gently pouring chilled champagne. Express a lemon twist over top.
