Cold Brew vs. Cold Drip: The Difference

Cold extracted tastes different — milder, sweeter, less acidic. But cold brew and cold drip are not the same. Here, explore how method (immersion or percolation), ratio, grind size, time, and roast shape the result.

Cold Brew vs. Cold Drip — The Difference

Cold Brew (Immersion): The coffee remains fully submerged in cold water throughout the entire steeping process, slowly saturating it. Result: soft, sweet, full-bodied, low acidity. Cold Drip / Kyoto (Percolation): Cold water slowly drips through the coffee bed, continuously introducing fresh solvent. Result: clearer, livelier, more acidity and aromatic complexity.

Cold also means slow. At room temperature, caffeine and chlorogenic acid reach their equilibrium only after about 6–7 hours (they increase fastest in the first ~3 hours). And importantly: Cold brew contains less titratable acid than hot brewed coffee at a comparable pH — which is why it tastes milder. Here, time is real physics (it compensates for the slow cold kinetics) — but the decision is still made based on concentration, ratio, and taste.

Sources (scientific): Fuller & Rao (2017), "The Effect of Time, Roasting Temperature, and Grind Size...", Scientific Reports (kinetics & equilibrium ~6–7 h); Rao & Fuller (2018), "Acidity and Antioxidant Activity of Cold Brew Coffee", Scientific Reports (less titratable acid than hot brew).

What You Need

For cold brew (immersion), a vessel like the Hario Mizudashi or a French Press is sufficient; for cold drip, a drip tower. Both — and the suitable filter and cold brew vessels — can be found with us. Plus fresh beans (medium roast yields more caffeine and chlorogenic acid than dark).

Frequently Asked Questions

What is the difference between cold brew and cold drip?

Cold brew is an immersion: The coffee sits in the water the entire time — the result is soft, sweet, and full-bodied with low acidity. Cold drip (Kyoto) is a percolation: Water slowly drips through the bed — the result is clearer, livelier, and more aromatically complex.

How long does cold brew need to steep?

Caffeine and chlorogenic acid reach equilibrium at room temperature after about 6–7 hours. Many still steep a concentrate for 12–24 hours and then dilute it. There's no right or wrong — dilute to taste.

Is cold brew less acidic?

Yes. While the pH is similar to hot brewed coffee, cold brew contains less titratable acid — which is why it tastes milder and less acidic.

What grind size and roast?

A rather coarse grind size is suitable for cold brew. Medium roasts deliver more caffeine and chlorogenic acid than dark roasts; dark roasts taste rounder and more chocolatey.
