This is the way Dr. Bunsen Honeydew and Beaker would try to brew coffee. The vacuum brewing process of the Pebo is entirely sealed off so no aroma can escape. This method of brewing the coffee also ensures that all the flavorful oils are extracted from the coffee as it is brewed. The Bodum Pebo makes every pot smell as fresh as it tastes. Have no fear, Bodum has perfected this age old method of making coffee, meaning even Beaker would escape this tasty experiment without scolding.
