Light tan foam over fairly lively chestnut ale, this Flemish oud bruin has a tangy vinegary sweet aroma. This beer is far less sharp than my previous Flemish experiences of this sort from Rodenbach Grand Cru yet bigger than the other Flem I have known Petrus Oud Bruin. There is a creaminess with all the acidity that is really surprising. "Vineous" may work with other examples of this style but this one is clearly ale, even if quite tart. If you go with it, it is also quaffable...maybe if you transpose from fruit juice as it is somewhere between granny smith apple and pineapple juice just in terms of tartness. But, with all that, there is also cherry and oak and vanilla and maybe the best Pepsi you have ever had as well as even dried fruit like prune and fig and molasses. Yes, as complex and balanced as a fine wine if you need to compare.
This is perhaps the best chance you will have to taste what a medieval ale was like. $4.95 for a 330 ml at the LCBO. Try one and a half in a hefeweizen glass if you can. BAers generally on board.
