The Tom Collins is one of the most iconic gin cocktails in the world. I have been making this refreshing drink for over a decade, and it remains my go-to recommendation for anyone new to cocktails. This classic recipe combines gin, fresh lemon juice, simple syrup, and club soda to create a bright, bubbly drink that is perfect for warm afternoons and casual gatherings. In this guide, you will learn exactly how to make a Tom Collins cocktail at home with just a few ingredients and no special equipment required.
What makes the Tom Collins so special is its simplicity. Unlike many cocktails that require shaking with ice, this drink builds directly in the glass. The result is a tall, refreshing sipper that balances the botanical notes of gin with tart citrus and gentle sweetness. Whether you are hosting a summer party or just want an easy drink after work, this recipe delivers every time.
Tom Collins Ingredients
A Tom Collins drink is made of just four essential ingredients. The quality of each component matters, but you do not need expensive spirits to make a great version. Here is what you will need:
- 2 ounces gin – London Dry gin works best, but any quality gin will do
- 1 ounce fresh lemon juice – Always use freshly squeezed, never bottled
- 1/2 ounce simple syrup – Equal parts sugar and water, dissolved
- Club soda – To top up the glass, about 3-4 ounces
- Garnish – Lemon wheel and maraschino cherry
- Ice – Plenty of fresh ice cubes
The magic of this cocktail comes from the balance between these elements. The gin provides the backbone with its juniper and botanical notes. Fresh lemon juice adds brightness and acidity that cuts through the sweetness. Simple syrup rounds everything out without overwhelming the other flavors. Finally, the club soda adds effervescence and dilutes the drink to a refreshing, sessionable strength.
When selecting your gin, I recommend starting with a classic London Dry like Beefeater, Tanqueray, or Bombay Sapphire. These offer clean, juniper-forward profiles that shine in a Tom Collins. If you want to experiment, try an Old Tom gin for a slightly sweeter, more rounded flavor that pays homage to the cocktail’s origins.
How to Make a Tom Collins Cocktail
Making a Tom Collins is remarkably simple. You do not need a cocktail shaker or any specialized bar tools. Just a glass, a spoon, and your ingredients. Follow these steps for a perfect drink every time.
Step 1: Build the Base
Start with a Collins glass or highball glass. Add the gin, fresh lemon juice, and simple syrup directly into the empty glass. This creates the foundation of your cocktail. The order does not matter much here, but I prefer adding the gin first so you can measure it accurately before the glass gets crowded.
Step 2: Add Ice
Fill the glass with fresh ice cubes. You want the glass about three-quarters full. Good ice is important here because it chills the drink and provides proper dilution. Use ice straight from the freezer, not ice that has been sitting out and partially melting.
Step 3: Top with Soda
Pour club soda over the ice to fill the glass. Leave about half an inch of space at the top. The amount of soda is flexible based on your taste preferences. More soda makes a lighter, more refreshing drink. Less soda creates a stronger cocktail with more pronounced gin and lemon flavors.
Step 4: Stir and Garnish
Gently stir the drink with a bar spoon or long spoon to combine the ingredients. Do not stir too vigorously or you will lose the carbonation. Then add your garnish. A lemon wheel and maraschino cherry are traditional, but feel free to get creative with citrus twists or seasonal fruits.
Serve immediately while the drink is cold and bubbly. The Tom Collins is best enjoyed fresh, as the carbonation will fade over time. If you are making multiple drinks for guests, prepare them one at a time rather than batching them in advance.
The History of the Tom Collins
The Tom Collins has a fascinating history that dates back to the 19th century. The cocktail first appeared in writing in Jerry Thomas’s 1876 edition of “The Bartender’s Guide,” one of the most important cocktail books in American history. However, the drink likely existed in some form before that publication.
The name “Tom Collins” is believed to come from the type of gin originally used. “Old Tom” gin was a popular style in England during the 18th and 19th centuries. It was slightly sweeter than the London Dry gin most people use today, with a fuller body and less aggressive botanical profile. When this style of gin fell out of favor, drinkers switched to London Dry, but the cocktail’s name remained.
Some historians trace the cocktail even further back to the 1700s and a headwaiter named John Collins who worked at Limmer’s Old House in London. He reportedly served a similar drink made with genever, the Dutch predecessor to modern gin. This connection explains why some cocktail books list both a Tom Collins and a John Collins as separate drinks.
Tom Collins vs John Collins: What is the Difference?
The difference between a Tom Collins and a John Collins comes down to the base spirit. A Tom Collins uses gin, specifically Old Tom gin in its original form. A John Collins uses whiskey, typically bourbon or rye, as the foundation. Both drinks follow the same basic formula of spirit, lemon juice, simple syrup, and soda water.
Today, most people use the name “Tom Collins” regardless of which gin they choose. If you see “John Collins” on a menu, expect a whiskey-based drink. The Collins family of cocktails has expanded to include versions made with vodka (Vodka Collins), tequila (Juan Collins), and other spirits. All share that same refreshing, tall format that makes them perfect for sipping.
Tips for the Perfect Tom Collins
After making hundreds of Tom Collins cocktails over the years, I have picked up a few tricks that elevate the drink from good to exceptional. Here are my best tips for getting it right every time.
Use Fresh Lemon Juice
This cannot be emphasized enough. Bottled lemon juice contains preservatives and lacks the bright, zesty character of fresh-squeezed citrus. The difference is night and day. I juice my lemons right before making drinks, and the flavor is significantly superior.
Make Your Own Simple Syrup
Homemade simple syrup is incredibly easy and tastes better than store-bought versions. Combine equal parts granulated sugar and water in a saucepan. Heat gently until the sugar dissolves completely. Let it cool, then store in a clean bottle in the refrigerator for up to one month. You can also make rich simple syrup using two parts sugar to one part water for a sweeter, more viscous result.
Choose the Right Glass
A true Collins glass is tall and slender, holding about 12 to 14 ounces. It is designed specifically for this family of drinks. If you do not have Collins glasses, a highball glass works perfectly well. The key is using something tall enough to accommodate the ice, spirits, and soda while leaving room for stirring and garnishing.
Adjust to Taste
The classic recipe calls for half an ounce of simple syrup, but this is flexible. If you prefer a tarter drink, reduce the syrup to a quarter ounce. For those who like sweeter cocktails, increase it to three-quarters of an ounce. I always recommend tasting before adding the final garnish and adjusting if needed.
Tom Collins Variations to Try
Once you master the classic Tom Collins, experiment with these popular variations:
- Vodka Collins – Replace gin with vodka for a cleaner, more neutral flavor profile
- French 75 – Swap the soda for champagne or sparkling wine for an elegant twist
- Southside – Add fresh mint and skip the soda for a herbaceous variation
- John Collins – Use bourbon or rye whiskey instead of gin for a warmer, richer drink
- Ramos Gin Fizz – Add egg white and cream, shake vigorously, and top with soda for a creamy, frothy version
