The BODUM mug press is not only a must-have in a single household, but it is useful for everyone who enjoys a cup of perfectly brewed coffee! The idea: fit the BODUM coffee press system into a mug to initiate a perfect brewing process on a very small scale. No sooner said than done, the BODUM mug press is made of stainless steel, fits into every mug (santroprene rim adapter) and comes with a plastic microwave-proof beaker (PP). Why? While the coffee develops its full taste in the mug, put milk into the beaker and warm it in the microwave (1min.), depress the plunger, take out the small mug press and pour the milk from the beaker into the mug, add sugar at your own taste and enjoy! All parts are dishwasher safe.
