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

The base spirit, mostly. Tom Collins runs on gin, John Collins runs on bourbon or whiskey. Everything else, the lemon, the sugar, the soda, the tall glass, stays the same. The bourbon makes the John warmer and rounder, with more vanilla and oak underneath the lemon. The bartending world has spent over a century swapping the names by accident, so don't be shocked if you order one and get the other.

Can I make this without simple syrup?

You can, but you'll be sad. Granulated sugar won't dissolve cleanly in a cold built drink, so you'll get grit at the bottom and a sour that fights you. Simple syrup takes two minutes to make. Equal parts sugar and hot water, stir until clear, cool it down. If you want a little more character, use a demerara syrup and let the bourbon and the raw sugar talk to each other.

Does the bourbon choice matter much here?

It matters, but don't overthink it. You want a workhorse bourbon with enough proof to stand up to the lemon and soda, not your prized single barrel. Something in the 90 to 100 proof range keeps the drink from going thin once the soda and melting ice get involved. Save the expensive stuff for a glass with one big cube and nothing else in it.

The John Collins: The Sour That Learned to Breathe

You have had this drink whether you know it or not. Bourbon, lemon, sugar, soda, served tall in a glass that sweats through a summer afternoon. The John Collins is the drink people reach for when they want something with a spine but not a fight. It goes down easy and asks almost nothing of you, which is exactly the kind of generosity most cocktails forget about.

2 ozBourbon

1 ozLemon Juice

0.75 ozSimple Syrup

Club Soda (top)

Garnish: Lemon wheel, cherry

This is a built drink, which means no shaker, no theater. You assemble it in the glass it lives in. Bourbon, lemon juice, and simple syrup go in first, then ice, then the soda goes over the top to lift everything. Give it one gentle stir, just enough to marry the parts without flattening the carbonation. The proportions matter more than the choreography. Two ounces of bourbon, a full ounce of lemon, three quarters of an ounce of syrup, and you have a sour in balance before the soda ever arrives. The club soda is not filler. It stretches the drink long, drops the proof into refreshment territory, and turns a tight, puckering sour into something you can nurse. Use real lemon juice, squeezed that day. The bottled stuff tastes like regret. Garnish with a lemon wheel and a cherry, drink it cold, and do not let it sit until the ice turns the whole thing to dishwater.

Strip the soda away and look at what's left. Bourbon, lemon, sugar. That is a sour in its purest arithmetic, a tart citrus balanced against a sweetener with a base spirit holding the room. The Cocktail Codex crowd files this under the Daiquiri family, and they're right to. The Daiquiri template is the complete sour: spirit, citrus, sweet, balanced so no single element wins. The John Collins is that template wearing a different hat. There is no daisy liqueur doing the sweetening, no orange curaçao or maraschino sliding in to complicate the sugar the way it does in an Aviation or a Brandy Crusta. Just simple syrup, plain and load-bearing. What makes the Collins itself is the soda water lengthening the sour into a long drink. The structure is identical to a Bee's Knees or a Brown Derby, citrus and sweet built around the spirit. The Collins simply gives that structure air and ice and time.

The name is a small disaster of attribution. There was a Tom Collins, built on gin, and the legend goes that a headwaiter named John Collins at a London hotel poured something similar enough that the names started trading places in the public memory. Swap the gin for genever or bourbon and the John Collins is what you get, depending on which century and which bartender you ask. Purists will tell you the gin version is the Tom and the whiskey version is the John, and purists are mostly right and entirely exhausting about it. The truth is this drink predates the cocktail nerd's need to sort everything into bins. It was a hot-weather refresher when air conditioning meant a shaded porch, and it survived because it does one thing extremely well. It quenches. The bourbon gives it a backbone of vanilla and char that the gin version lacks, and that depth is why the John Collins earns its own place on a menu instead of living forever in the Tom's shadow. Order one at a bar that respects citrus and you will understand why it outlasted a hundred flashier drinks.
