Brewing a great cup of coffee is a science. The amount of time the water is in contact with the coffee grounds directly relates to the final taste of the brew. The MT900 coffee maker brews coffee in less than one minute per cup which means coffee will never be over extracted or bitter. The extra-large sized shower head ensures that the coffee grounds are evenly saturated for perfect extraction with each brew. The removable water tank is completely visible without having to move the machine. The stainless steel thermal carafe keeps coffee hot and fresh for hours. A charcoal water filter is included with the machine, and an electronic counter registers how many pots of coffee have been brewed. Once it is time to replace the filter, an automatic LED light illuminates to alert you to make the change.
