First off, wow. Mega respect. Worships at the shrine of quads, etc, etc.
Now, I have to confess that this is a beer I have never had the opportunity of tasting, or sampling - or even laying envious eyes on. Westvleteren 12. Oh, wow. The Mecca or Shangdi-La of Stouts.
However, - and I write this as someone who loves the Belgian quad style of beer - I don't doubt that this was brilliant, but how does it compare with the other really good Belgian quads, beers such as the St Bernardus 12 (I believe that - at one stage - St Bernardus and Westvleteren shared brewing facilities) and the Trappistes Rochefort 10 (which some accounts suggest is possibly the closest in taste and style to the Westvleteren 12)?
