I made two fruit beer finds in Brussels last week. The first is Mandarin Mortal which struck me first with its incredibly amateur label. Presumably the brewers at Mortal, caring not for image quality, have their minds on more important things. From the mandarins I was expecting something sweet and Fanta-like, but instead got a marvellously bitter and peppery beer with the orange flavours playing second fiddle to the beer complexity. Great stuff and, icing on the cake, served in a stoneware ostrich eggcup. There really aren't enough beers served in stoneware, in my opinion.
The second hit was Bon Secours Myrtille. If your kitchen French isn't up to it (mine isn't) then the blueberries on the label are there to indicate what this is made with. It's dark red and heavily sedimented, giving off a strong blueberry aroma. On tasting, the wheat beer base lends texture, but stands aside to let the delicious sour fruit flavour come to the fore.
Brussels may be best known for making fruit beers from lambic, but so much more is available.
