Coffeemakers or
coffee machines are cooking
appliances used to brew coffee. While there are many different types of coffeemakers 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, a
cooking pot in the
kettle family. 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.
