A personal variation of the Cocchi Irlandese, the Cocchi Kentuckese is a nice sour with a bit of a twist on the irish version. Quite a bit more mild than a traditional sour, and the Cocchi Americano adds a great tasting smooth component. Almost too drinkable, and could be made with anything from a smooth low age bourbon to a complex high rye, aged spirit. Could be possible to add egg white to cocktail as well for a little more froth, but without it you still can have a great drink.
1 oz Bourbon
1 oz Cocchi Americano
1/2 oz fresh lemon juice
1/2 oz simple syrup
Shake all ingredients together with ice, serve in a lowball glass over a couple ice cubes and garnish with lemon twist. As an alternative you could add egg white and serve in a coupe glass (omitting the ice), both are great and refreshing cocktails.
