This Pro Series brew kettle is available in 10 or 15 gallon sizes. The 15 gallon brew kettle and 10 gallon brew kettle are made from 18 gauge professional grade stainless steel, and are some of the most heavy duty kettles on the market and are a great value for the price. They feature a 1/2" three (3) piece ball valve, rubber coated handles and a tri-clad bottom for even heat distribution. They also have a port for adding a thermometer. With graduated volume markers on the inside, there is no need for a sight glass. Lid is included!
