A remarkably simple and reliable brewer, the Bonavita 1901PW Metropolitan builds on several iterations of Bonavita coffee makers that we have enthusiastically endorsed for years. The optional pre-infusion mode allows for a better extraction from freshly roasted coffee, as the pre-infusion allows the coffee to degas before the brewing begins. This key feature - the bloom - addresses Bonavita's interest in helping consumers understand the importance of using fresh coffee, ground just before brewing.
With the powerful 1500-watt heater, this machine easily maintains the optimal brewing temperature of 198°-205°F. Most home coffee brewers fall short here. Which is one reason why this machine is recognized by the Specialty Coffee Association as part of its Certified Home Brewer Program.
