Tips & Notes

Pro tips

Muddle gently: press mint and sugar together just until the mint releases its oils; aggressive muddling bruises the leaves and creates bitter flavors.
Use fresh mint: older or wilted mint will result in a flat-tasting drink; pick bright green sprigs with intact leaves.
Add ice last: build the drink in order (sugar, mint, whiskey, carbonated water, ice) to ensure even mixing without dilution.
Serve immediately: carbonation fades quickly once the drink is mixed, so serve and drink right away for maximum freshness.

Substitutions

Old Mr. Boston Whiskey → any bourbon, rye, or Canadian whiskey (adjust to taste preference)
Green Mint → basil or tarragon (herbaceous note replaces mint freshness)
Carbonated Water → club soda, ginger ale, or tonic water (alters flavor profile)

Storage & make-ahead

Serve immediately after mixing. Pre-batch whiskey and mint mixture can be stored in the refrigerator up to 4 hours; add carbonated water and ice just before serving.

Equipment

muddler or wooden spoon · jigger or shot glass for measuring · bar glass or rocks glass

Common Questions

Can I make a Whiskey Smash without carbonated water?

Yes. Substitute still water, club soda, or ginger ale for carbonated water, though the carbonation adds essential lift and texture to the drink.

What's the best whiskey for a Whiskey Smash?

Bourbon, rye, or Canadian whiskey all work well. Bourbon offers sweetness, rye brings spice, and Canadian whiskey is smooth and approachable.

How do I muddle mint without bruising it?

Gently press the mint sprigs against the sugar in the glass using a muddler or wooden spoon. Avoid aggressive pounding, which releases bitter chlorophyll.
