Abstract: A method of preparing an extract can include loading extraction material into an extraction cell or a capsule extraction cell having a first portion and a second portion with ground coffee having a particle size between 200 ?m to 400 ?m. 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 75 seconds, 3 minutes, or 30 minutes 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, extract that has been extracted from the extraction material by the portion of the flow of extraction medium introduced into the extraction cell.

Abstract: Various beverage preparation methods are disclosed. The beverage preparation method can include purifying a first portion of an extract with reverse osmosis. The method can further include concentrating a second portion of an extract with freeze concentration, the first portion of the extract being separate from the second portion of the extract. The method can further include spray drying the first portion of the extract and the second portion of the extract to produce dried particles. The ratio of the first portion of the extract and the second portion of the extract can be at least 3:1.

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 ?m to 900 ?m. 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.
