How to Calculate Cold Brew Ratio
Common Ratios (Coffee : Water by weight)
Steeping
Steep ground coffee in cold or room-temperature water for 12-24 hours. Most recipes recommend 16-18 hours. Longer steeping increases extraction but can also increase bitterness.
Grind Size
Use a coarse grind (similar to French press). Fine grinds will over-extract and make the cold brew harsh and gritty.
计算示例
1 liter of cold brew concentrate (1:6 ratio), 18-hour steep.
- 01Coffee = 1000 / 6 = 167 g (about 2 cups)
- 02Water = 1000 mL
- 03Steep for 18 hours in the refrigerator
- 04Strain and dilute 1:1 for 8 servings of 240 mL each.
常见问题
Can I steep cold brew at room temperature?
Yes. Room temperature extraction is faster and may produce a slightly different flavor profile than refrigerator steeping. Steep for 12-16 hours at room temperature, then strain and refrigerate. Both methods work well.
How long does cold brew keep?
Strained cold brew concentrate keeps for up to 2 weeks in the refrigerator. Ready-to-drink strength keeps for about 1 week. The flavor gradually becomes stale and flat over time.
Is cold brew less acidic than hot coffee?
Cold brew is generally about 60-70% as acidic as hot-brewed coffee because cold water extracts fewer acidic compounds. This makes it gentler on the stomach for many people.
