Brewing Basics
Immersion Brewing
A brewing method where coffee grounds steep fully submerged in water for a set duration before being separated by filtration. The French press, AeroPress (inverted), and cupping bowls are classic immersion brewers.

Because the grounds and water remain in constant contact, immersion methods produce a more uniform extraction compared to percolation. Extraction slows as the surrounding water becomes saturated, making immersion relatively forgiving of minor grind or timing errors. The trade-off is a heavier body from suspended fines and oils that pass through metal or cloth filters.
