BeverageFactory.com offers a complete solution to dispensing Guinness® draft beer. In contrast to your standard carbonated beer, pouring Guinness® requires a specialty faucet, a "U" system coupler and a mixed gas high pressure tank. The faucet features a restrictor disc that slows down the pour to achieve the proper head. The Guinness® "U" system coupler is specific to Guinness® and Harp Lager kegs. Please call us at 1-800-710-9939 if you have any questions about our Guinness® beer kegerator conversion kits.
