Iced coffee from the press

Good iced coffee is not hot coffee gone cold — it is coffee brewed hot and chilled in seconds. The method is called flash brewing: steep concentrated, then pour straight over a glass packed with ice. Hot water extracts the acids and aromatics that give a coffee its character; the instant chill locks them in before they can fade the way they do in a cooling carafe.

The press version: 40 g of coffee, only 400 g of water — a deliberately tight 1:10 in the pot — steeped a full five minutes at a slightly finer grind, then pressed and poured over roughly 200 g of ice.

The math is the whole trick: melting ice is brew water you added late. 400 g of strong brew plus 200 g of melt lands the glass near 1:15 — exactly the balanced window from Chapter 1. Brew at normal strength instead and the melt dilutes you to thin, sad tea.

The finer grind and longer steep compensate for having less water doing the extracting. Serve immediately, while the ice is still cracking — that sound is the flavor being locked in.
