While there are many different types of coffeemaker using a number of different brewing principles, in the most common devices, coffee grounds are placed in a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot. Cold water is poured into a separate chamber, which is then heated up to the boiling point, and directed into the funnel. This is also called automatic drip-brew. Goodman's carries a full line of coffeemakers, automatic, stove top, percolator and urn models, by Braun, Cuisinart, Mr. Coffee, Krups, Bunn and more.
