Orval Trappist Ale

I have never drank anything like that. Tasted as if some port was poured into the brew. Very bitter. A truly acquired taste. Hated it to start with and then it slowly became more and more tanglible. "Semi-wild Brettanomyces yeasts give the beer a distinct subtle body and a refreshing tartness as an after effect. It is suitable for genuine connoisseurs and experts." says one website.
I fully agree. I also admit that I am not quite the expert yet...
