ABSTRACT:
A beverage is prepared employing a package (10) having a compartment (111) containing at least one beverage ingredient, e.g. roast and ground coffee. The package is located at a brewing station, an aqueous medium, e.g. hot water, is introduced into the package, the aqueous medium is allowed to commingle with the beverage ingredient, and the beverage so formed is collected through an outlet (38) formed in the package. The compartment of the package is sealed by a covering material (119) which determines one dimension of at least one opening (115) acting to filter the beverage passing out of the compartment to the outlet of the package. The package is also clamped at the brewing station prior to the introduction of the aqueous medium in a manner which maintains said one dimension during the subsequent formation and collection of the beverage.
