Petrus Oud Bruin

Good sour notes, but not very fruity ( perhaps slights hints of cherry). Has a slight bitter character as well.

Good but not great in my mind

Rodenbach Grand Cru

Quite tart! Prominent cherry, but no fruit added? Not particularly sweet, almost seems dry.

I'll recommend if a dry sour is desired but seems to lack the sweetness I like in a Flanders red.

Cuvee Chateau Kasteel

Good aged quality, dates and raisins with moderate esters. Ballance is a bit towards sweet.
Would recommend it when looking for a classic Belgium dark ale.
