What is an Infinity Bottle?

An infinity bottle — sometimes called a solera bottle or a blending bottle — is a single vessel that you add small pours from other bottles into over time. Every time you open a new bourbon, you contribute a shot or two to the blend. The bottle is never fully emptied; you drink from it while continuing to add to it, so the blend is always evolving.

The result is a completely unique whiskey that exists nowhere else in the world — a living record of every bottle you've ever opened, layered together into something greater than the sum of its parts.

As your blend grows, it becomes harder to remember what's in it. Tracking each addition lets you see the full history of your bottle — every bourbon that contributed, how much proof went in, and how the estimated proof of the blend has shifted over time.

Bourbonacci keeps a running weighted-average proof based on how many shots of each bourbon you added, so you always have a rough idea of what you're drinking.

1. Find an empty bottle — a 750ml bottle is the classic choice, giving you roughly 25 shots of capacity.
2. Open a bourbon you enjoy and pour 1–2 shots into your infinity bottle.
3. Log the addition in Bourbonacci — name, proof, and how many shots.
4. Repeat with every new bourbon you open. You can add as little as half a shot or as many as you like.
5. Whenever you want to drink from the blend, pour from the infinity bottle and log a removal.
6. Never fully empty it — leaving some in the bottle keeps continuity in the blend.

• Stick to a style — all bourbons, or all ryes, or a mix. Wild departures can throw off the balance.
• Higher proof additions will nudge the blend up; lower proof will mellow it.
• Don't overthink it. The whole point is that it's always changing.
• Label your bottle with the date you started it.
• Share the experience — pour a dram for friends and watch their reaction when you tell them what's in it.
