- Note: 1)Too coarse a grind, too little coffee, or insufficiently tamping the grounds before brewing can all lead to inadequate pressure for a proper brew. 2)It is important to note that the amount of espresso extracted will vary depending on the grind size and amount and reprogramming may be needed when the size and amount are adjusted.Filter type:Reusable - Material Type: Aluminum From the manufacturer Independent Hotplate The Coffee Brewer for Coffee Lovers Our hotplate is engineered with a heating element separate from the brewer boiling element. It rolls heat into the coffee, holding it at the perfect temperature while never burning it. We evaluate Moccamaster coffee brewers across the four T’s of coffee brewing: temperature, time, turbulence, and total dissolved solids (TDS). A brewer that performs within the ideal ranges of the four T’s produces the perfect ratio of coffee flavor compounds extracted into water, which the SCA refers to as “the golden cup.” That ratio creates the flavors we enjoy when we sit back with a good cup of coffee, and every Moccamaster hits that mark every brew cycle. Since 1968, Moccamaster coffee brewers have set the global benchmark for at-home coffee brewing. Designed to extract the maximum flavor from your grounds in about 4-6 minutes, coffee from a Moccamaster is comparable to what you would brew using a more complex manual process or drink in a cafe. We build our coffee brewers to last, using only the highest quality materials and offering replacement parts. With proper care and maintenance, this should be the last coffee brewer you ever need to buy.
