Abstract
A coffee brewer that includes a brewing chamber, and a brewing cup filled with coffee that is removably received in the brewing chamber. The cup includes a bottom that acts as a tamping member, and this bottom is movable to vary the size of the cup reservoir. Once the cup is positioned in the brewer, the closing of the cup forces engagement of the tamping member and an engagement member positioner in the brewing chamber, resulting in the tamping member being moved to compress the coffee.
