Abstract
A process for preparing a brewed beverage is presented. The process comprises providing a porous pouch containing an infusible material; at least partially immersing the pouch in water in a container; and subjecting the container to microwave heating under conditions effective to heat the water and to cause pulsation of the pouch.
Claims25
A process for preparing a brewed beverage, the process comprising:
- a. providing a pouch exhibiting a porosity which promotes steam buildup in said pouch and yet does not substantially hinder the free flow of extract from an infusible material and/or water, said pouch containing an infusible material;
- b. at least partially immersing said pouch in water in a container;
- and
- c. subjecting said container to microwave heating sufficient to heat said water and to cause pulsation of said pouch to provide a drinking strength brewed beverage.

A process for preparing a brewed beverage, the process comprising:
- a. providing a pouch having a porosity of no greater than about 250 ft.sup.3 /min. of air/ft..sup.2 at 0.5 inches of water pressure, and containing about 4 grams to about 10 grams of roast, ground coffee or about 1 gram to about 4 grams of tea;
- b. at least partially immersing said pouch in about 5 ounces to about 8 ounces of water in a container;
- and
- c. subjecting said container to microwave heating at less than full power sufficient to heat said water and to cause pulsation of said pouch to provide a drinking strength brewed beverage

A process for preparing a brewed beverage comprising:
- a. providing a pouch formed of a hydrophobic material having a porosity of about 100 to about 220 ft.sup.3 /min. of air/ft.sup.2 at 0.5 inches of water pressure and containing about 4 grams to about 10 grams of roast, ground coffee or about 1 gram to about 4 grams of tea;
- b. at least partially immersing said pouch in about 5 ounces to about 8 ounces of water in a container;
- and
- c. subjecting said container to microwave heating at about 75% to about 85% power sufficient to heat said water to about 170.degree. F. to about 210.degree. F. and to cause pulsation of said pouch to provide a drinking strength brewed beverage.
