Abstract
A method and apparatus producing high-quality coffee extract is disclosed. The apparatus contains a base module, extraction chamber and an extract holding chamber. The base module contains a pumping means that recirculates the extract liquid within the extract chamber to ensure efficient and thorough extraction. When extraction is complete, the pumping means will pump the extract liquid into an extract holding chamber where it can be detached from the extraction module and placed wherever desired. The liquid extract can be dispensed whenever needed and will have an extended shelf life.
