Having tasted over 100 Belgian beers now -- well beyond the original expectation of the 40b40 -- I have had to make a few changes to my list of top ten Belgian beers, adding Chimay Grande Réserve (aged) and Floreffe Prima Melior. I made some space on the old list by combining Rochefort 6 and Rochefort 10 into one entry and lumping Floreffe Prima Melior with the Floreffe Dubbel that was already on the list.
If you think this combining is cheating, I can only say I refuse to have a rerun of the great Corsendonk Crisis. Feel free to sue me. I am 100% confident the law is on my side in this.
I also slightly downgraded Achel Brune in my top ten. It's still there under the entry for Achel Brune Extra -- a phenomenal beer -- but I've been having worrying thoughts about the regular old brune. I tried it again during the Ardennes winter retreat in a blind taste test, and I have to say I wasn't very impressed. In fact, it tasted like a completely different beer, not my beloved malt-loafy brew. I am going to have to do more research to resolve this question.
In any case, please have a look at the list of top ten Belgian beers, and let me know if you think I've got it right.
