Drie Fonteinen is known for the amazing Lambic beers they produce. But those beers take time, so it makes sense that the lambic brewers supplement their sour stocks with some more traditional beer.
And a sour porter is about as traditional as it gets for Armand at the 3F brewery. (Well that’s not quite true, as he makes a blond and also a lager too.)
A normal porter is made, using the yeast from the Beersel Blond beer. It is then refermented in the bottle using a lambic yeast which includes a Brettanomyces strain.
The result is a dark beer with an inviting smell of roasted malt, chocolate, dark stone fruits and yeast. The flavour combines these attributes so that the beer is very porterish, with justthe subtle character of the lambic yeast.
