Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
86 words
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.
