Brass Stout FaucetThis NADS Brass Stout Faucet is a traditional pub style faucet used primarily with low carbonated ales or stouts. This is the type of faucet most often used with a nitrogen CO2 mix. Before being dispensed, the beer is forced through a restriction disc that degasses the beer and creates a creamy white head. The brass stout faucet comes with a stainless steel nozzle so you do not impart any off flavors in your beer. Proposition 65 Warning for California
