Whiskey Smash

Pro tips

• Muddle the mint gently and briefly—3–4 light presses—to release oils without bruising or bitterizing the leaves.
• Use fresh, fragrant mint with no discoloration; quality mint is essential since it's the dominant flavor.
• Chill your glass with ice before building the drink to keep it cold longer without over-dilution.
• Top with carbonated water just before serving; flat or stale soda dulls the drink's brightness.

Substitutions

• Old Mr. Boston Whiskey → any bourbon or rye whiskey (adjusts sweetness and spice profile)
• Green Mint → basil or tarragon (changes herbaceous character; use sparingly as basil is more assertive)

What's the difference between a Whiskey Smash and a Whiskey Sour?

A Whiskey Smash uses muddled fresh mint and carbonated water instead of citrus juice and egg white, making it lighter and more herbaceous than a traditional Sour.

How much should I muddle the mint?

Gently muddle the mint 3–4 times to release oils without bruising the leaves, which can turn them bitter.

Can I make this ahead?

No. Muddle and serve immediately; the mint loses potency and the drink becomes watery if prepared in advance.

What type of whiskey works best?

Bourbon or rye whiskey are traditional; choose a mid-range spirit (80–100 proof) for balanced flavor without harsh alcohol bite.

Can I use simple syrup instead of a sugar lump?

Yes. Use ½ oz simple syrup in place of the sugar lump for easier mixing, though a lump produces better mint extraction through muddling.
