I will be in Europe for a couple weeks in April, specifically Paris for a week or so (with a relative) then Belgium/Netherlands for a few days on my own. I'll probably visit a Trappist brewery or two and also plan to purchase a boatload of beer to bring back. I was curious how easy it is to get some of the harder-to-get-in-the-U.S. Trappist beers in Belgium. Unfortunately it seems the cafe that sells Westvleteren is inexplicably closed for a week in April, the same week in which I'll be there, so Westy is out of the question. However, I do want to bring back a decent amount of Westmalle, Rochefort, Chimay, and, potentially, La Trappe. Are these easily purchasable in Belgian stores (or, in the case of La Trappe, Dutch stores) in bulk 12oz bottles? I'm mostly interested in Westmalle - generally the two main stores I go to for beer around my house only have 1-2 bombers and bottles of it on the shelf at any given time, and the 12 ouncers go for around $6 a piece.
