The Cup-One is a single-serve brewer that makes a 10 oz cup of coffee. An excellent alternative to pod machines, it’s a sustainable choice and allows you to brew your favorite coffee one cup at a time using Moccamaster technology. Each Cup-One arrives with 3 boxes of #1 filters, enough for 240 cups. How it works: Brewing on your Cup-One 1. Fast Brewing Time Simple to use with a quiet brew process, the Cup-One brews a 10 oz cup of coffee in about 4 minutes. 2. Consistent Temperature The copper boiling element rapidly heats water to a brewing temperature of 196°F - 205°F and automatically shuts off when the water reservoir is empty. 3. Precise Engineering The boiling action moves the water up the glass tube, where it flows into the outlet arm and pulses over the brew basket, blooming the coffee grounds in a manual pour-over coffee style. 4. OPTIMIZED COFFEE EXTRACTION The cone-shaped brew basket steeps the coffee grounds, extracting the coffee's full flavor and maximizing its complexity, taste, and aroma. 5. REMOVABLE CUP HOLDER The removable cup holder allows you to fit different size cups under the brew basket with a clearance of about 5 inches. Golden Cup Standard: The Four T’s What makes good coffee so good? It comes down to the coffee solubles extracted into your water. The coffee industry has defined scientific benchmarks for perfectly brewed coffee, called the Four T's. Temperature A consistent brewing temperature between 196°F - 205°F is essential for the extraction of coffee solubles. Time A saturation time of 4 - 6 minutes releases the full flavor of the coffee without over- or under-extracting it. Turbulence Agitation of the coffee grounds generated as the water flows through the grounds creates even saturation. Total Dissolved Solids (TDS) This is the ratio of coffee solubles to water that the brewer extracts. The ECBC defines ideal TDS yield as between 18% - 22%, and the SCA refers to this as “the Golden Cup.” Moccamaster coffee brewers hit this mark every brew cycle.
