A single serving brewing cartridge adapter fits into known single serving horizontal coffee makers and allows use of a common single serving cartridge made for a vertical coffee maker. The cartridge adapter includes a fixed extraction needle in the base of cartridge adapter and defines walls rising from the base to guide a cartridge into position. The extraction needle pierces a single use cartridge to release brewed beverage into the cartridge adapter. An injection needle in the horizontal coffee maker lid punctures a foil cover of single use cartridges and passes through a permanent opening in a lid of the cartridge adapter and an extraction needle in the horizontal coffee maker cooperates with the cartridge adapter to carry brewed drink from the cartridge adapter. Reusable cartridges including permanent openings to receive the injection needle and to release brewed beverage may also be used with the cartridge adapter.
