Vacuum brewed beverage method
View Patent ↗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.
1. A beverage brewing process comprising the steps of:
placing a desired amount of a solid beverage brewing material into a chamber at atmospheric pressure;
placing a desired amount of water into said chamber;
sealing said chamber from the surrounding atmosphere;
creating a vacuum within said chamber by drawing a vacuum utilizing a vacuum source located outside of said chamber;
allowing said brewing material and water to brew in said chamber under the influence of said vacuum for a desired period of time;
removing said vacuum from said chamber thereby allowing the pressure in said chamber to return to atmospheric pressure,
repeating the steps of creating a vacuum within said chamber, allowing said brewing material and water to brew in said chamber under the influence of said vacuum and again removing said vacuum from said chamber, and
separating said brewed liquid from said solid to created said beverage.
2. The beverage brewing process as claimed in claim 1 wherein the vacuum within said chamber is maintained in the range of about −5 to about −20 inches of mercury during each said brewing step.
3. The beverage brewing process as claimed in claim 1 wherein the temperature of said water is in the range of about 185° to about 212° F. when it is placed into said chamber.
4. The beverage brewing process as claimed in claim 1 wherein the temperature of said water is maintained in the range of about 185° to about 212° F. during said brewing step.
5. The beverage brewing process as claimed in claim 1 wherein separating said brewed liquid from said solid to created said beverage is accomplished by the use of a filter.
6. The beverage brewing process as claimed in claim 1 wherein said chamber has an open top and wherein said step of sealing said chamber includes placing a cover on said open top.
7. The beverage brewing process as claimed in claim 6 wherein said cover is placed on said open top by moving said chamber upwardly to seal against said cover.
8. The beverage brewing process as claimed in claim 1 wherein said chamber is comprised of a glass vessel.
9. The beverage brewing process as claimed in claim 1 wherein said beverage brewing material is comprised of ground coffee.
10. The beverage brewing process as claimed in claim 1 wherein said beverage brewing material is comprised of tea leaves.
