Abstract
A method for producing aqueous extracts from ground coffee, by adding coffee to a vessel; adding heated water to the vessel; stirring the resulting coffee-water mixture during a predetermined brewing time to produce an even distribution of coffee in the mixture and to allow expulsion of gas from the mixture; and filtering the coffee-water mixture at the end of the predetermined brewing time to produce a filtered aqueous coffee extract.
