Ratio's Thermal Carafe is designed for use with the Ratio Eight and Ratio Six coffee machines, but also functions as a stand alone thermal serving device for coffee or tea, and as a manual pour over vessel with a matching ceramic cone. It holds 40 ounces, or 1.25 liters.The Ratio Thermal Carafe combines function, elegance, and durability. The double wall carafe body will keep your coffee hot for up to 90 minutes after brewing. The 304 stainless steel handle and 18/8 stainless steel dewar body are resistant to corrosive coffee acids and oils.The counterweighted handle makes pouring feel natural and well-balanced. The precision pouring spout directs the coffee right into your cup, without any drips or dribbles down the side of the carafe.The Ratio Dripper is designed to rest on top of the carafe. The sturdy porcelain walls help to maintain temperature stability, and include ridges to keep the coffee filter from sticking to the side of the dripper. The dripper is designed to be used with Chemex filters or the Ratio Kone by Able.
