I wouldn't drink anything that had anything to do with monks, quiet or not.
Kanterbrau has always been a preference as its not as sweet as Kronenbourg, and usually cheaper.
I suspect that this is my imagination as if you search the web you'll see that Kanterbrau are owned by Kronenbourg, who are owned by Scottish and Newcastle. I.e. its Fosters, not Heineken
Anyone for a Becks?
