This should be the last coffee Carafe you'll ever buy, one that should last a lifetime, when cleaned and descaled properly. You may ask – “What's important when searching for that complex, clean, crisp, fully infused, flavorful cup of coffee?” Certainly coffee quality, grind and formula play an important role, as does the fresh water quality, but ultimately, it’s the brewing method that plays the all-important final role! Moccamaster Carafes are designed scientifically to naturally brew with an ultra-precise, pre-immersion drip-style system, which creates a natural pulse action process creating the perfect coffee bloom process. Moccamasters incorporate a powerful and energy efficient copper heating element with an automatic shut-off when brew process is complete, a precise coffee-water saturation time (4-6 minutes), and an independent 2-phase hot-plate element that maintains the correct holding temperature (175°-185° F) for 100 minutes (although we recommend consumption within 30-minutes).
