Abstract
The desired amount of coffee grounds, tea leaves, herbs or other beverage making material is placed in a chamber of glass vessel located on a moveable table top in its lowered position. The table top is then elevated until the upper edge of the vessel seals against a top seal. With the top sealed, the desired amount of water of about 185°-212° F. is introduced into the chamber through a port in the top. Thereafter, a vacuum is drawn in the chamber and is held within the range of about −5 to −20 Hg in. Using an external heat source, the brewing liquid is maintained at about 185°-212° F. Alternatively, the vacuum can be pulsed by turning it on and off several times during the brewing cycle. After the beverage has brewed for the desired amount of time, the heat and vacuum are removed, the chamber is returned to atmospheric pressure and the table top is lowered to release the vessel. The contents of the chamber are then strained to remove solids from the beverage.
