A drip-type coffee maker with efficient heat transfer and minimal heat loss keeps coffee at the optimum temperature for proper flavor over an extended period of time. A closed-top decanter formed entirely of plastic heat insulating material fits into a well which contains a recessed aluminum warming plate. The warming plate is heated to a temperature only slightly above the desired temperature of the coffee. A warming plate adapter is provided for converting existing coffee makers.

A coffee maker comprising: a brewing and dispensing unit for brewing and discharging coffee; a decanter constructed of heat resistant thermal insulative plastic for receiving coffee discharged from said brewing and dispensing unit and formed with a bottom portion of a predetermined configuration; a warming table for receiving the decanter and maintaining the brewed coffee warm therein; a heat conductive warming plate mounted on said table and formed with a dished out well having a bottom wall and raised a peripheral wall with peripheral walls configured to complementally receive said bottom portion of said predetermined configuration to enhance heat conduction thereto, and; a heating element in thermal communication with said well whereby said decanter may be positioned with said bottom portion nested in said well in direct contact with said peripheral wall for direct heat conduction from said well to said bottom portion. A coffee maker for use at room temperature of about 68°F. to brew coffee and maintain it at a warm temperature and comprising: a brewing and dispensing unit for brewing and discharging the brewed coffee; a decanter formed with thermally insulative plastic walls defining a chamber for receipt of a predetermined volume of brewed coffee discharged from said brewing and dispensing unit and being formed with an open top and a bottom portion having a predetermined configuration, said decanter including a lid to cover said open top, said walls and lid providing sufficient thermal insulation to, when said cavity is substantially filled with said predetermined volume of coffee at substantially 180°F. at room temperature of about 68°F., limit the heat transfer from said coffee to a predetermined rate; a warming plate for receiving said decanter and formed with a thermally conductive well configured to receive said bottom portion in close fitting heat exchange relationship, said warming unit including a heating element operative to maintain a selected temperature of about 200°F., said heating plate being constructed of a heat conductive material having a sufficiently high heat transfer coefficient to cooperate with said heating element, well, and decanter to form a heat path from said heating element into said decanter, having a sufficiently low resistance to heat transfer to, when said heating plate is at said 200°F., transfer said heat to said brewed coffee at said predetermined rate.
