double brew coffee

Many machines offer multiple cup sizes—commonly 5 oz and 8 oz—plus single and double espresso options. Some models also provide larger coffee sizes such as 12 oz and 18 oz.

Pods include flavored options (for example, caramel), and some are described as light roast. Several pods are made from 100% Arabica beans, are caffeinated, and are labeled as recyclable through the capsule recycling program.

Capsule machines use different capsule types/sizes for coffee versus espresso and typically employ a centrifugal extraction system. The machine can read a capsule barcode to set brewing parameters, allowing it to produce single or double espresso shots on demand.

Capsule machines often use barcode-driven centrifugal extraction that automatically sets brewing parameters for consistent shots. Semi-automatic machines rely on high pressure, PID temperature control, low-pressure pre-infusion, and a commercial-style portafilter to support repeatable double-shot extraction.
