STAINLESS STEEL STOUT TAP
This specialty stout tap can be used for Irish Stouts gassed up with mixed gas. You can see a video of this here. https://vimeo.com/108849080
Mixed gas cylinders contain 80% Nitrogen and 20% Carbon Dioxide. Once a stout is brewed, if mixed gas pressure is placed on top of the beer at the clarification stage, after a minimum of 4 days at 1.9 bar pressure, enough nitrogen will have gone into the beer to give it that Guinness-type pour. So this can be made in 9 days in a WW.
However this special tap is also needed as it has a fitting inside called a sparkler that forces the nitrogenised beer through 5 small holes to create that special foamy nitrogen pour.
This tap can be swapped onto the WilliamsWarn Brewery font to pour a beer directly out of the WilliamsWarn or you could brew a normal stout in the WW and transfer to a kegging system that has mixed gas pressure on it for at least 4 days and this tap employed as the beer tap.
