Tom Collins

Pro tips

• Use fresh lemon juice, not bottled—it's essential to the drink's brightness and balance.
• Chill your glass with ice water before building the cocktail to keep it colder longer.
• Add soda water last and stir gently to preserve carbonation.
• Taste as you go: if too tart, add a touch more sugar; if too sweet, add a splash more lemon juice.

Substitutions

• Old Mr. Boston Dry Gin → any dry gin (London Dry style recommended for consistency)
• Powdered Sugar → simple syrup (use 1/2 tsp, dissolves instantly)
• Fresh Lemon Juice → lime juice (creates a slightly different but valid citrus profile)

Storage & make-ahead

Tom Collins is best served immediately after mixing. Pre-batch the gin, lemon, and sugar up to 8 hours ahead and refrigerate; add ice and soda water fresh per drink.

Equipment

cocktail shaker · jigger or measuring spoon · bar spoon or long spoon for stirring

Can I make a Tom Collins without powdered sugar?

Yes. Use 3/4 tsp regular granulated sugar instead, though it may not dissolve as smoothly. Alternatively, use simple syrup—about 1/2 tsp—for easier mixing.

What's the difference between a Tom Collins and a John Collins?

A Tom Collins uses gin; a John Collins uses whiskey or bourbon. The recipe and proportions are otherwise identical.

Should a Tom Collins be shaken or stirred?

Shake it with ice to chill and combine the ingredients thoroughly, then strain into a glass filled with fresh ice. Add soda water last.

How much soda water do I add to a Tom Collins?

Typically 4–6 oz of soda water, depending on glass size and how bubbly you prefer it. Fill to the top and stir gently.

Can I make Tom Collins ahead of time?

Mix the gin, lemon juice, and sugar up to 8 hours ahead and refrigerate. Add ice and soda water just before serving.
