Beer Pressure Barrel with Four Inch Cap

For storing up to five gallons of beer under pressure. This barrel has a four-inch diameter cap with integral pressure safety valve (in case your beer is a bit too lively!), and a valve to allow the use of a CO2 gas cylinder (in case you need to add more pressure). It has a 'drum tap' at the bottom for easy pouring.

With a four inch cap, there is plenty of space to get reach inside when cleaning the barrel for the next brew.
