Cold Brew Coffee (Slow Cold Immersion) vs. Espresso (Standard Double Shot 1:2)
Comparing 2 standards across 11 specifications. 11 key differences identified.
Cold brew coffee is prepared by steeping coarse coffee grounds in room temperature or chilled water (4–20°C) for 16–24 hours. Per 100ml concentrate, it delivers 180–220mg caffeine with 66% lower titratable acidity than hot brews.
A standard double espresso is prepared by forcing 9 bars of pressurized hot water (90–93.5°C) through 18g of finely ground coffee in 25–30 seconds, yielding 36g of liquid beverage. Per 100ml, it delivers ~212mg caffeine, an 8.5–11.0% TDS, and a persistent crema emulsion.
