Percolation Method

Percolation brewing drives water through coffee grounds using gravity (pour-over) or pressure (espresso). It is one of two fundamental brewing approaches alongside immersion. In pour-over percolation, water application technique (pulse pouring, continuous pour, blooming) affects channeling and extraction evenness. The filter medium - paper (removes oils, clean cup), metal (more oil, fuller body), cloth (intermediate) - significantly alters the final mouthfeel. Percolation typically produces brighter, higher-acidity cups than immersion.
