Tips & Notes

Pro tips

Gently slap the mint sprigs in your palm before muddling to release oils without bruising the leaves, which turns them bitter.
Add the sugar lump and a small amount of carbonated water to create a paste before muddling—this helps dissolve the sugar evenly.
Top with carbonated water last to preserve effervescence; don't stir vigorously after adding it.
Serve immediately after assembly; the drink loses its brightness and carbonation quickly.

Substitutions

Old Mr. Boston Dry Gin → any London Dry gin (Tanqueray, Beefeater) or gin of choice
Carbonated water → soda water or club soda (neutral effect)
Sugar lump → 0.5 tsp superfine sugar or 0.5 oz simple syrup (adjust proportions slightly)

Storage & make-ahead

Serve immediately after making. This drink is not designed for advance preparation or storage.

Common Questions

What's the difference between a Gin Smash and a Mint Julep?

A Gin Smash uses gin and carbonated water, while a Mint Julep uses bourbon and is stirred with ice rather than built fresh. The Gin Smash is lighter and more effervescent.

Can I make a Gin Smash without fresh mint?

Fresh mint is essential to the drink's character—it's muddled to release oils. Mint syrup or extract won't deliver the same bright, herbaceous flavor.
