1. A method of making a portion capsule for use with a beverage making machine to make a beverage, the beverage making machine incudes a pump, an optical detector, a mandrel, and a seal, the method comprising:
forming a metal material into a base element that includes: i) a wall extending around a central longitudinal axis to define a cavity, and ii) a rim having a top side and an opposing bottom side;
filling the cavity with a beverage material;
closing the cavity by attaching a foil cover onto the top side of the rim, the foil cover being dimensioned and configured to be: i) pierced by the mandrel of the beverage making machine in a piercing region that is laterally offset from the central longitudinal axis, and ii) sealed by the seal of the beverage making machine in a sealing region that is located between the piercing region and an outer perimeter of the rim; and
providing an optically detectable identifier onto the metal material so that the optically detectable identifier results on the opposing bottom side of the rim, the optically detectable identifier having sections that differ optically;
wherein the optically detectable identifier is configured to be read by the optical detector of the beverage making machine, and the pump is activated to supply hot water after the optically detectable identifier is read by the optical detector and compatibility of the portion capsule is determined based upon information obtained using the optically detectable identifier.
