Bavik is an old fashioned Belgian brewery, and Petrus (7.3%) is an old fashioned beer. It is, according to Bavik, an ‘undiluted’ old beer. It is aged in wooden vats, which judging by smell are funkier than if Bootsy Collins, George Clinton and the whole Parliament-Funkadelic ensemble got together and made some extra smelly blue cheese. It’s a dark golden amber colour, the head doesn’t last much. I was surprised given the smell that it wasn’t more sour, now don’t get me wrong, it is sour, but it’s not Cantillon sour; perhaps it’s more that it doesn’t finish dry, it’s not especially puckering. It is similar to red sour Flemish beers like Rodenbach and Vichtenaar, it has that same almost balsamic sweetness coming through, it could be the oak I think that given the fact that it doesn’t finish that dry, it could have been more highly carbonated, as it is the gas is weak, and it sits a little flat in your mouth. I love this flemish sour thing though, and this is a really nice example.
