Immersion Brewing Method

Immersion is one of two fundamental coffee brewing categories (the other being percolation). Ground coffee and water remain in full contact throughout brewing. Time and ratio are the two primary variables. French Press (4 min / 1:15), AeroPress (1-2 min / 1:15), cold brew (12-24 h / 1:8), and cupping protocol (4 min / 1:18.18) all use immersion. The method is forgiving: grind inconsistency has less impact than in percolation because all particles extract simultaneously.
