Coffee making apparatus and methods provide a tamped packing of loose ground coffee thereby obtaining richer flavor. The Coffee maker includes a reservoir, a pump, a heater, and a check valve. Coffee grounds are first loosely deposited in a coffee holder and then tamped onto a compacted state. The coffee holder may be filled loosely with the coffee and then placed into the coffee making apparatus and compacted, or the coffee may be compacted in the coffee holder and then the coffee holder placed into the coffee making apparatus. The compacting may be by a spring or by a resilient solid material and may be part of the coffee holder or part of the coffee making apparatus.
