Coffee makers are kitchen appliances that make it possible to brew coffee beverages without needing to boil water using a separate container. Different types of coffee makers are available today. The principles of brewing with various coffee makers differ. In the common coffee making appliances the coffee grounds are placed in a paper or metal filter inside a funnel set over a glass or ceramic coffee pot. A separate chamber is there which heats up the water and directs it into the funnel. This is the automatic drip-brew process. A number of other brewing processes are there too- some of which are highly advanced and acclaimed. With a huge variety of coffee makers available today it has indeed become a difficult task to choose the very best among coffee makers. As a solution it is advised that you need to decide what exactly you are on the lookout for.
The idea of a vacuum coffee maker is to heat water in the lower vessel of the brewer until the expansion forces the water through a narrow tube into an upper vessel that contains the coffee grounds. When the lower vessel has more or less emptied itself and enough time has elapsed the heat is removed and the resulting vacuum will draw the brewed beverage through a strainer back into the lower chamber from which it can be stored. The device must usually be taken apart to pour into a mug. An early variation of this principle is called balance siphon. This variation has the two chambers arranged side by side on a balance like device with a counterweight attached to the heated chamber.
