A new brewpub near my home is set to open next weekend, called the "Crafty Chameleon". Looking at their list of bottles available, I noticed they listed Rochefort 12. I never seen nor heard of a Rochefort 12. Does it exist?
More than likely its the 10, a bar here did the same thing, actually they still haven't changed it on their site, but it's the 10.
Easy to accidentally call it 12 since Westvleteren and St. Bernardus also use that number for their quads.
