So at Blackbird we recently stepped our game up.... We installed a carbonation system and a 4 tap draught cocktail system. I won't bore you with the details but one of these drinks is an Americano. We made 15 variations, this is the winner, which you can make with a very bubbly bottle of seltzer.
1.5oz Contratto Americano Vermouth
1.5oz Cappalletti Apertivo
Build in Collins glass over ice, top with seltzer. Garnish with orange twist. Enjoy.
