DIY Recipe Calculator

Your drink, two chambers.

Type the single-drink recipe. We scale each side to fill its chamber — the mixer blend stays true to the original, the spirits too — and the dial does the rest.

Cold brew, lemonade, iced tea, kids' drinks — the pnümix works the same with nothing stronger than coffee.

Single-drink recipe as you'd make one glass

Enter one glass the way you'd make it by hand. Each line has its own amount and unit — oz, ml, tablespoons, teaspoons, or dashes.

Fill the pnümix

How the math works

Each side is scaled to fill its chamber — 17 oz insert, 28 oz thermos, 45 oz total — so you get the most drinks out of one fill.
The blend inside each chamber matches your single drink exactly. Two mixers at 2:1 stay 2:1.
The dial sets how much of each chamber ends up in the glass, so everyone gets the strength they want from the same fill.
If the strong side is more than half the drink, it goes in the thermos and the dial reads in reverse.
Small measures convert at bar standards: 1 tbsp = ½ oz, 1 tsp = ⅙ oz, 1 dash = 1/32 oz (about 1 ml — the amount a dasher top releases in one shake). Dashes aren't exact and don't need to be. Anything under 1 oz in the fill list is shown in tablespoons or teaspoons so you can measure it with what's in the kitchen drawer.
