A device for brewing a beverage comprises a chamber for containing a beverage-making substance, which prevents compaction of substance, wherein the chamber extends a substantial distance above the beverage-making substance. The beverage-making substance, such as ground roasted coffee beans, is retained within the brewer by filters installed in openings at the base and upper ends of the chamber. Seals are secured over the base and upper end openings to preserve the freshness of the beverage-making substance. A user prepares a beverage by removing the seals and moving the device with an up and down motion through water in a cup. The upper end of the brewer is open to the atmosphere, and a pressure head develops between the upper and lower portions of the brewer which greatly increases water flow through the substance. Filaments or protuberances within the device prevent the compaction of wetted beverage-making substance and greatly enhance the free swirling of substance and liquid leading to a quicker and more efficient brewing process.
