Tom Collins Recipe — Gin, Lemon & Soda Over Ice
The Tom Collins is the definitive gin highball: gin, fresh lemon and sugar lengthened with cold soda over plenty of ice. It appears in Jerry Thomas's 1876 Bartender's Guide, making it one of the oldest documented mixed drinks still poured exactly as written — proof that simple formulas survive when the balance is right.
What Makes It Special
Carbonation changes everything. Dissolved CO2 forms carbonic acid on the palate, adding bite that lets the drink carry more dilution than a still cocktail without tasting thin. That is why a Collins stays refreshing to the last sip while a flat version of the same ingredients would taste watery halfway down.
What Makes It Special
This classic cocktail is particularly beloved for its unique blend of flavors and elegant presentation.
Ingredients
- 2 oz (60ml) Gin (London Dry)
- 1 oz (30ml) Fresh Lemon Juice
- 1/2 oz (15ml) Simple Syrup (1:1)
- 3–4 oz Chilled Soda Water
- Lemon wheel and cherry, for garnish
Step-by-Step Instructions
- Chill the glass: Fill a Collins glass with ice and let it sit while you build — a cold glass keeps the soda lively.
- Shake the base: Add gin, lemon juice and syrup to a shaker with ice. Shake 8–10 seconds.
- Strain over fresh ice: Dump the warming ice from the glass, refill with fresh cubes, and strain in the shaken base.
- Top with soda: Pour chilled soda water down the side to preserve bubbles. Stir once, gently.
- Garnish: Add a lemon wheel and a cherry.
The History Behind the Recipe
The Tom Collins first appears in print in Jerry Thomas's 1876 edition of The Bartender's Guide, and it is named for Old Tom gin, the slightly sweetened style that preceded London Dry. The drink survived Prohibition, the vodka decades and the cocktail revival without changing — a rare straight line through 150 years of drinking history.
Presentation and Visual Appeal
Pale gold and sparkling, served tall over glistening ice with a lemon wheel and cherry. The rising bubbles do most of the visual work — keep the soda cold and pour it last so the effervescence arrives at the table intact.
Pro Tips and Variations
Use a dry, assertive tonic-style soda water rather than sweet club alternatives; the drink has enough sugar already. For a John Collins, swap the gin for bourbon or rye — same build, completely different drink. A splash of elderflower liqueur in place of half the syrup makes a fresh, floral variation without unbalancing the sour structure.
This cocktail embodies the essence of classic mixology – simple ingredients combined with expert technique to create something truly extraordinary.
Frequently Asked Questions
What is the difference between a Tom Collins and a John Collins?
A Tom Collins uses gin; a John Collins uses whiskey (modern bars usually pour bourbon, though the original called for Holland gin). Same sour-plus-soda architecture, different backbone.
How much soda should I add?
Enough to fill the glass — typically 3–4 oz over the shaken base. Too little and the drink is syrupy; too much and the gin disappears. Taste after 3 oz and top up to your preference.
Which gin style works best?
London Dry is the default — its juniper bite survives dilution. Old Tom gin (sweeter, rounder) is historically apt and makes a softer, vintage-tasting Collins.
