Wacaco Company Limited announces the launch of Prestina, a patented manual coffee brewer designed to turn a user’s cup into a built-in press. The company describes a brewing process that uses four components and delivers a roughly one-minute infusion, producing coffee in a single cup. According to the company’s materials, Prestina requires no electricity and does not use paper filters. Instead, the brewer relies on the cup itself to actuate the pressing mechanism, aiming to provide a simplified workflow while keeping the output focused on the coffee grounds and the pressed extraction. Multiple releases from PR Newswire present the same core concept: “Your Cup. Your Press,” with the product positioned as a compact, manual alternative for making coffee without electrical power. The announcements originate from Wacaco’s Hong Kong base and state that the product is patented, but they do not provide additional independent testing or performance comparisons in the excerpts provided.
