Definitions, ratios and protocols behind this recipe.
- Cold brew Cold brew is filter coffee's slowest cousin. You drop coffee and cold (or room-temperature) water into a vessel, leave it for 12–24 hours, and then strain. No heat, no pour, no fuss. Time replaces temperature as the extraction lever.
- Brewer families Brewers split into three families by how water meets coffee. Each family has a character. Knowing which family you're using tells you what kind of cup to expect — and which mistakes are easy to make.
