This unit offers BUNN brewing perfection with the Classic, stainless steel accented design that customers have loved for years. Patterned after BUNN"s commercial & restaurant brewing systems, this home brewer puts high quality materials and classic brewing technology into one great package. The stainless-steel tank holds the brew water at approximately 200˚F, the temperature required to extract the maximum flavor from coffee. The patented BUNN brewing system showers the water over the ground coffee using a specially designed sprayhead to create optimum turbulence in the funnel for just the right amount of time. As a result, BUNN home brewers produce 10 cups of perfect coffee in about 3 minutes --- less than half the time of most regular coffee makers. This combination of "time, temperature & turbulence" is the hallmark of BUNN"s home brewing system --- and something unavailable in any other home brewer. This is a high-altitude version of the BUNN thermal home brewer with stainless steel vacuum insulated carafe and stainless accents. Specially engineered thermostat for use above 5,000 ft.
