Aeropress

Comparison of brewing methods: Drip Brewing: Drip brewing passes water through a bed of grounds. When the water first drips into the bed, it is too hot and bitterness is extracted. As the water filters downward through the bed, it becomes too cool and extraction is weak. The water doesn't contact all of the grounds uniformly. Grounds at the edge of the bed are under-extracted, while grounds at the center are over- extracted and contribute bitterness. Total immersion of the grounds in the AEROPRESS completely solves these problems. All of the grounds contact the same water temperature, and the brewing process is short and sweet. The gentle air pressure of the AEROPRESS also extracts extra flavor from the coffee. Ordinary drip brewers leave a lot of flavor in their soggy grounds. The drip method cannot make a robust single cup because the small amount of water doesn't heat the bed enough for rich extraction. It is also slow. AEROPRESS makes one to four servings with a single pressing in less than a minute. The flavor is equally rich for any number of cups. The lengthy wet time of drip brewing also extracts bitterness from the grounds.
