ON TAP TWO NIGHTS ONLY!!! We like it when the brothers go big. First there was the Voodoo Porter, weighing in around 7% and so good it won a medal at last year's Australian International Beer Awards. Then came the funk: James Brown, the big Belgian armed with 1000kg of candi sugar that won an army of fans and was described by Biero's beer man as "bananas coated in Nutella - awesome!". And now they're back with their biggest beer yet: The Guvnor. An English barley wine packing a whopping 10.3% of heat, it's being tapped this afternoon at the brewery in Moorabbin and will be pouring from the bright tank until close of business tomorrow (Friday). And then that's your lot. Well, not quite your lot, as the remainder will be bottled in the fancy limited release packaging the Voodoo and JB appeared in, with maybe a couple of kegs heading to other venues at some point. Brewer Andrew Ong says: "It's definitely the biggest beer we've ever produced. Mashed with a buttload of English pale and crystal malts the colour is a deep amber. We put a few bottles through our accelerated ageing test, and the beer produces really full rum and raisin notes." Some - maybe all - of the bottles will be held and aged, so if you want bragging rights, you'd best get busy.
