Mini Barrel System Upgrade
29 April 2019
After extensive trials and testing we've made some significant
improvements to our mini barrel system, increasing their
reliability and consistency as well as improving the quality of
You should use the barrels exactly as before, though the trials
did highlight the importance of taking off the tap after
We would also advise that you open the tap
fully to pour the beer.
Why Removing the Tap is So Important?
Inside the mini barrel is a canister of CO2 gas. When a tap is
placed onto the barrel, the canister is opened, and gas enters a
space above the beer and is held there under pressure. When the
beer is poured, the gas pressure pushes the beer out and more gas
enters the barrel. If the tap is kept on, then the gas, under
pressure, may be absorbed by the beer. As the beer absorbs more and
more CO2, the danger is it will become over-gassed so when you next
pour, you'll get froth. There is also a risk that if the beer can
absorb too much, then the gas canister may empty and there will not
be enough gas to push beer out.
Removing the tap reduces the chance of the beer picking
up too much CO2 and the barrel running out of gas to dispense the
