Coffee slushie basics for a slush machine
Cold brew or chilled strong coffee is the base; hot coffee melts the batch and slows the freeze. One tested starting point for a 1.85 L batch: 1,100 ml cold brew, 300 ml whole milk, and 450 ml 1:1 simple syrup, which lands at 14.9° Brix. Cold dulls both sweetness and bitterness, so a mix that tastes slightly too sweet at room temperature is usually right once frozen.
Milk and cream add fat and foam. Keep dairy to a third of the batch or less, blend it in cold, and expect a creamier, slower freeze than a juice slush.
| Drink | Cold brew | Whole milk | 1:1 syrup | Brix |
|---|---|---|---|---|
| Cold brew coffee slush | 1,100 ml | 300 ml | 450 ml | 14.9° |
FAQ
Coffee Slush Recipes: common questions
Yes. Sweeten cold coffee to the 12–16° Brix zone, which clears the 4% sugar minimum, and run the slush program. For milk-heavy mixes the milkshake program handles dairy better.
Yes, with the vodka and coffee liqueur held to a hopper ABV under about 8%. The catalog's espresso martini slush is the balanced version; the coffee liqueur supplies part of the sugar.
Not with stevia or sucralose alone, because sweetness is not what freezes. A bulk sweetener such as allulose can stand in for sugar; the sugar-free guide explains the ratio.
Slushable is a free app and recipe library for home slush machines. Every recipe is rebalanced to the right sugar (Brix) and alcohol (ABV) so it actually freezes into a smooth slush — no watery puddles or rock-solid blocks.
These recipes are dialled in for countertop slush machines like the Ninja Slushi. You can still blend them as a frozen drink, but the sugar and alcohol are tuned specifically so they freeze cleanly in a machine.
Yes. Every recipe is free to browse here, and the Slushable app is a free download. Open any recipe in the app to scale the batch to your machine and run a guided freeze.
It's almost always the Brix or ABV. Too much sugar or alcohol stops a mix from freezing; too little turns it to ice. Slushable works those numbers out for you, so each recipe lands in the slushable zone.
Absolutely. The library has plenty of zero-proof, family-friendly recipes alongside the frozen cocktails, all balanced to the same fluffy texture.
