Abstract
The invention provides a method of extracting a beverage material comprising the steps of a) at least partially filling a first extraction chamber with an extractable beverage material; b) conveying at least one extraction fluid through at least said first extraction chamber to provide an extract; c) modifying said extraction fluid temperature before conveying extraction fluid through at least said first extraction chamber at a second extraction temperature to provide a secondary extract. The invention further provides an apparatus for preparing a beverage.
Claims25
A method of extracting a beverage material comprising the steps of:
- a) at least partially filling a first extraction chamber with an extractable beverage material;
- b) conveying at least one extraction fluid through at least said first extraction chamber to provide an extract;
- c) modifying said extraction fluid temperature before conveying extraction fluid through at least said first extraction chamber at a second extraction temperature to provide a secondary extract;
A method of extracting a beverage material comprising the steps of
- a) at least partially filling a first extraction chamber with an extractable beverage material;
- b) conveying at least one extraction fluid at a first extraction temperature through the extractable beverage material in the first extraction chamber to provide an extract;
- c) conveying said extract at the first extraction temperature through at least a second extraction chamber at least partially filled with an extractable beverage material to provide an enriched extract;
- d) modifying said extraction fluid temperature before conveying extraction fluid through the extractable beverage material in the first extraction chamber at a second extraction temperature to provide a secondary extract;
An extraction apparatus comprising one or more extraction chambers each of them configured to retain an extractable beverage material during an extraction process;
- an extraction fluid inlet at the bottom of each extraction chamber configured to introduce an extraction fluid through the extractable beverage material;
- an extract outlet at the top of each extraction chamber configured to remove an extract from the extractable beverage material;
- and wherein the apparatus further comprises a heating element configured to independently modify the temperature of at least some of the extraction fluid passing through each extraction chambers.
