Tom Collins

Tom Collins recipe: a classic that still feels sharp and current

If you want a long gin drink that tastes clean, cold, and genuinely refreshing, the Tom Collins is still one of the best formulas in the classic cocktail canon. It is simple on paper, but that is exactly why the details matter. Fresh lemon makes a visible difference. Good ice matters. So does holding back on the shake and adding soda at the end.

This page is built for the search intent people actually have when they look for a Tom Collins recipe: what goes in it, what the correct ratio is, how to make it at home, and how to stop it tasting watery after two minutes.

The classic Tom Collins ratio

Start with this:

• 2 oz gin
• 1 oz fresh lemon juice
• 0.75 oz simple syrup
• 3 oz soda water

That balance gives you enough citrus bite to feel bright, enough sweetness to round it out, and enough soda to make it unmistakably a Collins rather than just a gin sour poured tall.

Best ingredients for a Tom Collins

• London Dry gin is the safest choice if you want a classic finish.
• Fresh lemon juice gives the drink its lift and keeps it from tasting dull.
• Simple syrup is easier to control than sugar added directly to the glass.
• Cold soda water should be opened right before you top the drink.

If your gin is very floral, you can reduce the syrup slightly. If your lemons are especially sharp, add a little more syrup a bar spoon at a time rather than guessing up front.

How to make a Tom Collins without turning it flat

The key is to shake only the base. Gin, lemon, and syrup get a short shake with ice to chill them. Then you strain over fresh ice and add soda water last. That keeps the top lively and prevents the drink from feeling tired too quickly.

The garnish is classic for a reason: a lemon wheel or slice gives aroma without changing the drink too much. A cherry is optional. If you want the old-school hotel-bar presentation, add it. If you want a cleaner look, skip it.

Variations worth trying

1. Drier Tom Collins: reduce the syrup to 0.5 oz.
2. Softer botanical version: use a lighter floral gin and garnish only with lemon.
3. If you like long refreshing builds: try Paloma or Aperol Spritz.

Common mistakes

• Too sour: your lemons are strong, so add a small extra measure of syrup.
• Too sweet: reduce syrup before reducing soda, otherwise the drink gets short and heavy.
• Flat texture: stale soda or too much stirring.
• Watery finish: too little ice or too much time spent shaking.

Why the Tom Collins still works

The name is tied to the 1874 Tom Collins hoax, but the history is not why the drink survived. It survived because it solves a real drinking occasion beautifully: you want something longer, colder, and easier to keep sipping than a Martini, but cleaner and less sugary than a lot of modern crowd-pleasers.
