The Clover single serve coffee maker is now available at Starbucks. Starbucks has acquired the Clover company earlier this year.
The barista pours ground coffee onto an extremely fine filter atop a piston that descends into the machine. After the coffee steeps, the piston rises, creating a vacuum that pulls water through the grounds. The finished coffee flows through a spout into a waiting cup. Despite its price tag, a Clover can increase cafe owners’ profits by allowing them to charge more per cup according to the bean.
