The invention is comprised of a rotating glass coffee bean gas flame torrefaction drum which roasts and rapidly grinds fresh coffee beans. This feeds a brewing device designed to accelerate making solid ice as quickly as possible in order to arrest the hydrolysis kinetics of 2-furfuryrlthiol. The heat exchanger portion has exceptionally high surface area heat exchanger coils.Higher mass exchange of the device prevent specific chemical component flavor loss. In addition, the torrefaction process in the glass drum attached to the device with rapid grinding process allows for much higher levels of 2-furfurylthiol in ice cubes. The glass allows visualization of the flame.The consumer enjoys of the product visually and by smell prior to product consumption.
