Abstract
A beverage is prepared employing a package containing at least one beverage ingredient, e.g. roast and ground coffee. The package (10;200) is located at a brewing station, the package is pierced by a tool (49;248) to form an outlet opening (38;202) in the package, 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 the outlet formed in the package. The piercing tool is employed both to form the outlet opening, and to fold the material (117;204) surrounding the opening out of the path of the beverage which subsequently emerges through the outlet opening.
