A plastic drum tap, complete with a plastic back nut, for fitting to brewing bins and wine fermenters or as a spare tap for barrels. Perfect spare tap for King Kegs. Fitting a tap to your fermenting vessel makes it easy to rack the beer or wine off the yeast at the end of primary fermentation. You could also fit it to the secondary storage vessel and use it to facilitate bottling beer or wine, preferably via a syphon tube so as to avoid aerating the brew, though this is not its intended use and you would be better off fitting a Little Bottler to carry out this job.
