To properly pour Guinness and achieve the famous and unique head on the beer requires a specialty European Stout Beer Faucet. The faucet operates by pulling forward and down on the tap handle. In addition, this economy stout faucet features a restricted spout that contains a tiny disc. The restrictor disc helps slow down the pour and allows the beer to pour properly. If you need to pour regular beer with this faucet, just remove the restrictor disc.
