## Abstract

The present disclosure includes an extraction assembly for use in an automatic brewer. The extraction assembly includes controllably extracting espresso beverage from a quantity of brewing substance. The assembly facilitates improved control and operation of the extraction assembly and improves the reliability of the extraction assembly. Generally, the brewing substance is compacted between a pair of opposing pistons. The pair of pistons operates relative to a brew chamber for use in the espresso extraction process. An alternative extraction assembly or structure for brewing beverage is provided which may include a larger brew volume, enhanced structures, and removable replacement components. Also provided is a heating element in close proximity to the brew chamber. Heat form the heating element can be brought directly to the area in which the coffee is brewed to help maintain a more consistent, tighter tolerance temperature and faster recovery between brew cycles.

## Claims

### Claim 1

A beverage extraction assembly which allows for removal of a prior assembly and replacement with a new and enhanced assembly suing the same structures.

### Claim 2

A beverage extraction assembly having a removable brew chamber cup for replacement thereof.

### Claim 3

A beverage extraction assembly having a brew chamber including a heating element positioned in close proximity to a cavity defined by the brew chamber.
