The classic French Press steeps coarsely ground coffee in hot water for four minutes, then filters it by pressing a metal mesh plunger to the bottom. It is one of the oldest and most widely used immersion brewing methods.
The metal mesh filter does not remove coffee oils and fine particles, which gives the French Press its characteristic full body and richness. It is the method most different from paper-filtered brewing.
Medium-dark and dark roasts where body and richness are the goal. Colombian, Brazilian, and Sumatra single-origins work especially well.
