Keurig and Single-Serve

Single-serve brewing trades cost per cup for speed and zero waste: a fresh cup in about a minute with no leftover pot. Within that trade, the machines differ more than they look. Keurig's MultiStream models saturate grounds more evenly than single-needle brewers, Nespresso's Centrifusion spins a thicker crema than any K-Cup can, and machines with reusable filters cut the pod cost to near zero. This guide compares ten machines on the numbers that matter: cup sizes, reservoir capacity, pod compatibility, and what each cup actually costs you over time.

Every pick below brews a single cup fast, but half of them also handle grounds or full carafes for households that want flexibility. Where a machine locks you into a pod ecosystem, we say so plainly.
