Abstract
Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are shown. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.
