It is the simple and beautiful alternative to the coffee machine: the French Coffee Press. The elegant French coffee press WMF CoffeeTime is made of mouth-blown, double-walled WMF quality glass, whose insulating properties keep the coffee warm for longer. The lid is made of high-quality plastic, and the press is made of Cromargan. Here’s how coffee works in the French Coffee Press: First, add the desired amount of coffee grounds to the pot and pour boiling water over it. Let the coffee steep for a while, then slowly press the plunger down. The fine mesh pattern of the aroma chambers allows the liquid to pass through, but not the swollen coffee grounds.
