The brewery say:
Why chew it when you can brew it?
We've dialled it up the vaultage of Iron Brew's iconic flavour, adding a burst of bubble gum among each sip of sour sweetness.
Turn your tongue blue with this brew, as we pay homage with a Vault City variation of the nation's favourite soft drink, now with added caffeine for those late night kick off times!
