Drip brew is a method for brewing coffee which involves pouring water slowly over coffee contained in a paper filter. Water seeps through the coffee absorbing its oils and essences, then goes through the bottom of the filter which separates coffee grounds from the liquid, and into a carafe or pot.
Drip brewing is the most popular method of coffee brewing, owing to the overwhelming popularity of the automatic drip brewing coffee machine. There are, however, several manual drip-brewing devices on the market, offering a little more control over brewing parameters than automatic machines.
Compared to other brewing methods such as French press or Espresso, in which the brewing water doesn't go through a paper filter, drip brewing produces clear, light-bodied coffee, which is free of sediments but also of some of coffee's oils and essences which can get trapped in the paper filter.
