- What is the best ratio for cold brew coffee?
- The standard cold brew ratio is 1:8 — 1 part coffee to 8 parts cold water by weight (e.g. 100 g coffee + 800 g / 800 ml water). This produces a ready-to-drink cold brew of normal strength. For a concentrate intended to be diluted before serving, use 1:4 (100 g coffee + 400 ml water).
- How long do you steep cold brew?
- At room temperature (18–22°C): 12–16 hours. In the refrigerator (4°C): 18–24 hours. Steeping longer produces a stronger, more bitter concentrate; less time gives a lighter result. Cold brew should always be strained before serving.
- Is cold brew the same as Italian caffè freddo?
- No. Italian caffè freddo (cold coffee) is typically a hot espresso that has been chilled or a shakerato — espresso shaken with ice until frothy and served over ice. Cold brew is a fundamentally different method: coffee is never heated and is steeped in cold water for hours. Cold brew is a more recent trend in Italian bars, though caffè shakerato has been a summer staple for decades.
- What grind size should I use for cold brew?
- Cold brew requires a very coarse grind — similar to coarsely ground sea salt. An extra-coarse grind (900–1200 microns) prevents over-extraction during the long steep time and makes filtering easier. Using a fine grind produces a murky, bitter result.
- How long does cold brew keep in the fridge?
- Properly filtered cold brew keeps for 7–14 days in a sealed container in the refrigerator. Cold brew concentrate keeps slightly longer due to its lower water activity. Always strain thoroughly — coffee grounds left in the liquid accelerate deterioration.
