Bourbon and Coke: The Ratio, the Ice, and Why Jack Isn't Bourbon

A guy once sent back a bourbon and Coke because I made it with Jack. He was right. I was wrong. I bought his next one.

That was my first month behind a stick. Busy Saturday, gun in one hand, the closest brown bottle in the other. Jack Daniel’s sits right next to Jim Beam on most rails, and to a new bartender they look like the same drink. They aren’t, and some customers can tell.

Jack isn’t bourbon

Jack Daniel’s is Tennessee whiskey. On paper it’s made almost exactly like bourbon. Mostly corn. Aged in new charred oak barrels. The difference is one extra step. Before it goes into the barrel, the new spirit drips through a tall bed of sugar maple charcoal. That’s called the Lincoln County Process. Tennessee law requires it for anything labeled Tennessee whiskey.

The charcoal strips out some of the rough edges and leaves a softer, sweeter whiskey. Banana, caramel, a little smoke. Bourbon tends to come across bigger. More vanilla, more oak, more spice.

So a Jack and Coke is a Tennessee whiskey and Coke. Close cousin. Not the same glass.

The ratio

One part bourbon, two parts Coke. Two ounces of bourbon, four of Coke.

That’s stronger than most bars pour it. Most bars go 1:3 or worse, and the bourbon disappears. Coke is loud. There’s caramel and vanilla in there, plus citrus oil and a lot of sugar. It takes a lot of whiskey to stand up to it.

Pouring cheap bourbon? Go 1:3 and let the Coke carry it. Pouring something you like? Stay at 1:2. I’d never go below that with a good bottle.

Ice, and a lot of it

Fill the glass to the top. Every bourbon and Coke I’ve seen go bad went bad here.

Half a glass of ice melts fast. Melt water flattens the soda and thins the bourbon. Two sips in, you’re drinking sweet brown water. A full glass of ice stays cold longer and melts slower. It sounds backwards. It isn’t.

Here’s the build I used for years:

1. Highball or rocks glass, packed with ice.
2. Two ounces of bourbon.
3. Four ounces of cold Coke, poured slowly down the side.
4. One short stir. That’s it. Every extra stir knocks out bubbles.

Cans or bottles beat the soda gun. Gun Coke is usually flatter and the syrup mix drifts. If you have glass-bottle Mexican Coke, made with cane sugar, use it. It tastes a little cleaner. Some people swear by it. I just think it’s nice.

Which bourbons

Jim Beam. The default, and cheap. The database has it as the plain Jim Beam and Coke, and the JB Black and Pepsi uses the longer-aged Beam Black against Pepsi. More oak. Better drink.

Maker’s Mark. Wheat instead of rye in the mash. Soft and round, no spicy bite. Very easy with Coke. A good pick for people who think they don’t like bourbon.

Wild Turkey 101. Higher proof, lots of rye spice. It punches through Coke better than anything else on the shelf. If you like your bourbon and Coke to taste like bourbon, this is the bottle.

Buffalo Trace, Four Roses, Evan Williams. All fine. Evan Williams is the budget hero. I’ve seen CocktailBuilder list hundreds of bourbon recipes, and honestly the brand matters less in this one than in almost any other.

What I’d skip: anything expensive, anything over about 110 proof. Expensive bourbon is wasted under all that sugar. Barrel-proof stuff needs so much Coke to tame it that you end up with a pint glass.

With lime

Squeeze a lime wedge in. It’s the single best upgrade. The acid cuts the sweetness and makes the Coke taste sharper. That’s why a Cuba Libre, which is basically a rum and Coke with lime, tastes better than a plain one.

The Bourbonime is exactly that build. Bourbon, Coke, lime. The Peg does the same with Wild Turkey and lime juice. Lemon works too. The Commodore Highball is Jim Beam, Coke and lemon.

Coke Zero

Coke Zero has no sugar. Sweetness comes from artificial sweeteners instead. With bourbon it reads thinner and a little drier, and the sweetener aftertaste shows more than it does with rum.

My fix is a heavier pour of bourbon and a lime wedge. The lime covers most of the aftertaste. Diet Coke is different again. Lighter, more citrus, a bit metallic with whiskey. Coke Zero is closer to the real thing.

One note people miss. Zero sugar doesn’t mean lighter on alcohol. Same two ounces of bourbon either way.

Bourbon and Coke vs rum and Coke

Rum is made from sugarcane or molasses. Even unsweetened, it reads sweet, and it melts right into cola. The flavors overlap. A Cuba Libre is dark rum, Coke and lime, and it’s smoother and rounder than the bourbon version.

Bourbon fights the Coke a little, and that’s the point. Vanilla and oak from the barrel line up with the vanilla in the cola. The spice from the rye cuts through the sugar. You get a drier, bolder drink. Spiced rum sits in between. A Captain and Coke tastes a lot like a bourbon and Coke with the edges sanded off.

For more cola builds, our drinks with Coke page goes through the rest of the bar.

What it’s called

Nothing fancy. Bourbon and Coke. People order it by brand. Beam and Coke. Maker’s and Coke. Turkey and Coke. Nobody at a bar will ask what you mean.

Technically it’s a highball. Same family as a whiskey and Sprite, with a darker soda.

A few to try after that

Cherry is the classic add. Jim’s Wild Cherries pairs Jim Beam and Wild Turkey with cherry cola. Sweet, but good. Jim Rogers adds grenadine instead, so it’s a grown-up Roy Rogers.

Amaretto is next. Beam Me Up is Jim Beam, amaretto and Coke. Tastes like an almond cookie. Goes down way too fast.

Dessert? A Bourbon Float. Bourbon, cola, a scoop of vanilla ice cream. Spoon and straw.

When the Coke runs out, the bourbon doesn’t have to sit. Our bourbon cocktails list covers the stirred stuff. I still order a Beam and Coke at ballgames. Lime, if they have it. They never have it.
