Abstract
A brewing system includes a brewing apparatus and a capsule containing a substance for brewing. The capsule has an opening on one side and a base on an opposite side. The base includes a light input surface, a light-output surface and a light conductor to conduct light from the light input surface to the light output surface. The apparatus includes: a brewing chamber including an inlet for heated water, an outlet for the brewed beverage, and an opening in communication with the opening of the capsule. A light source on the brewing apparatus emits light into the base via the light inlet surface of the capsule. The light conductor conducts the light to the light-output surface. A light detector of the brewing apparatus detects light emitted by light-output surface on the base of the capsule. A method of operating the brewing system and a capsule system are also described.
