ABSTRACT:
A coffee machine has an assembly provided with a chamber for receiving a permanent filter selected, according to the taste preference of a user, from a set of such filters which each offer different flow resistance to water per unit time. A pod of ground compressed coffee is also removably receivable in the chamber; the characteristics of pod and filter are so selected that during each operation of the machine between 22-26% of the total aromatic substances present in the coffee in the pod, are extracted by hot water flowing through the pod. However, due to the different flow resistance offered by different filters, the quantity of beverage produced during a predetermined operating time will vary. In dependence upon the particular selected filter, the extracted aromatic substances will therefore be more or less diluted in the beverage, to suit a particular taste.
