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. Play through here 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, slowly saturating it. Result: smooth, sweet, full-bodied, low acidity. Cold Drip / Kyoto (Percolation): Cold water slowly drips through the coffee bed, constantly 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 rise 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 based on concentration, ratio, and taste.

What you need

For Cold Brew (Immersion), a vessel like the Hario Mizudashi, the Varia Cold Brew bottle, or a French Press is sufficient; for Cold Drip, a drip tower. Both — and the matching filter and Cold Brew vessels — can be found with us. A consistently coarse grind is provided by a Varia grinder. 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 steeps in water the whole time — the result is smooth, sweet, and full-bodied with low acidity. Cold Drip (Kyoto) is a percolation: water slowly drips through the coffee bed — the result is clearer, livelier, and more aromatically complex.

How long should Cold Brew steep?

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

Is Cold Brew less acidic?

Yes. Although 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?

For Cold Brew, a coarser grind is suitable. Medium roasts yield more caffeine and chlorogenic acid than dark roasts; dark roasts taste rounder and more chocolatey.
