Abstract
A method of preparing a white coffee extract can include loading extraction material into an extraction cell having a first portion and a second portion. The extraction material can include ground coffee with a density between 0.2 g/ml-0.4 g/ml and a mean particle diameter between 700 μm to 900 μm. The method can further include introducing a flow of extraction medium through the first portion of the extraction cell. The method can include, within less than 60 seconds of introducing a portion of the flow of extraction medium into the extraction cell, withdrawing from a filter at the second portion of the extraction cell, the white coffee extract that has been extracted from the extraction material by the portion of the flow of extraction medium introduced into the extraction cell. The extraction material can include ground white coffee.
