The whiskey smash is a simple drink that is tailor-made for warm summer nights. What makes the smash such a great summer drink is how the combination of ice-cold lemon and mint chill out the whiskey. Smashes get their names from the way the ice smashes up the mint in the cocktail shaker. This is one of those great classic cocktails that deserves a comeback, and In case you're curious smashes used to be a big deal, according to cocktail historian David Wondrich, "From its first appearance in the mid 1840s, until after the Civil War, the Smash was just about the most popular thing going." And if it's up to us it will be again.
