Abstract
Temperature control for extracted beverages, including coffee, via controlled vacuum, and associated systems and methods are disclosed. A representative system includes a brew chamber, a beverage chamber in fluid communication with the brew chamber, a vacuum source in fluid communication with the beverage chamber, and a flow control device positioned to vary the force applied by the vacuum chamber on the brew chamber via the beverage chamber.
Claims24
A method for brewing a beverage, comprising:
- in a brew chamber, mixing water with solids;
- over a course of an extraction period, directing the beverage formed from the water and the solids from the brew chamber to a beverage chamber under a force applied to the brew chamber by a vacuum source;
- and
- changing the force applied to the brew chamber from a first, non-zero value during a first portion of the extraction period to a second, non-zero value, higher than the first value, during a second portion of the extraction period subsequent to the first portion of the extraction period.

- in a brew chamber, mixing water with solids;
- over a course of an extraction period, directing the beverage formed from the water and the solids from the brew chamber to a beverage chamber under a force applied to the brew chamber by a vacuum source;
- and
- changing the force applied to the brew chamber from a first value during a first portion of the extraction period to a second value, higher than the first value, during a second portion of the extraction period subsequent to the first portion of the extraction period,
- wherein, during the first portion of the extraction period, the beverage flows into the beverage chamber as a laminar flow.

A method for brewing a beverage, comprising:
- in a brew chamber, mixing water with solids;
- over a course of an extraction period, directing the beverage formed from the water and the solids from the brew chamber to a beverage chamber under a force applied to the brew chamber by a vacuum source;
- and
- changing the force applied to the brew chamber from a first value during a first portion of the extraction period to a second value, higher than the first value, during a second portion of the extraction period subsequent to the first portion of the extraction period,
- wherein changing the force includes increasing a flow area of a vacuum flow path coupled between the vacuum source and the beverage chamber.

A method for brewing a beverage, comprising:
- in a brew chamber, mixing water with solids;
- over a course of an extraction period, directing the beverage formed from the water and the solids from the brew chamber to a beverage chamber under a force applied to the brew chamber by a vacuum source, wherein directing the beverage includes directing the beverage upwardly into the beverage chamber through a port in a lower surface of the beverage chamber;
- and
- changing the force applied to the brew chamber from a first value during a first portion of the extraction period to a second value, higher than the first value, during a second portion of the extraction period subsequent to the first portion of the extraction period.

A method for brewing a beverage, comprising:
- in a brew chamber, mixing water with solids;
- over a course of an extraction period, directing the beverage formed from the water and the solids from the brew chamber to a beverage chamber under a force applied to the brew chamber by a vacuum source, wherein directing the beverage includes directing the beverage upwardly into the beverage chamber via a flow path, and directing the beverage downwardly toward a lower surface through an exit in the flow path;
- and
- changing the force applied to the brew chamber from a first value during a first portion of the extraction period to a second value, higher than the first value, during a second portion of the extraction period subsequent to the first portion of the extraction period.
