The #1 selling style of coffee machine in Europe brews coffee 10 times better because it does it naturally. The process of making coffee this way has been a fixture in Japanese and Scandinavian homes for over 40 years. "Upside-down" vacuum brewing separates coffee from grounds for clean, exquisite taste. The coffee maker works like this: water is held in the lower portion of the coffee pot and the coffee grounds are placed in the upper pot. When the water begins to boil, the vacuum process causes it to rise up through the tube to mix with the coffee grounds. The newly brewed coffee runs back down to the lower pot ready-to-serve, while the grounds stay in the upper pot. Makes 5 cups. Measures: 5.5” x 6.75” x 8.5”. Makes great gift!
