Released back in December ($20) and for some reason took off fairly quickly on the hype train. It was a brewery release that ended up seeing light distribution around LA/OC/IE and I believe some parts of SD. I think the bottle count was in the 3000 range but I can't quite remember so I'd defer to someone else on that. I'm not a huge imperial stout fan and didn't find it to really stand out but others seem to feel differently. I traded the second bottle I had a month or so ago in a larger trade that included a few Chocolate Rain bottles for a set of Armand’4s and a few other Cantillon bottles.
~3500 bottles released last December. ~$20 per 750ml bottle. Second bottling (~6000 bottles) slated for a December 2012 release I grabbed a couple of bottles right away. After having it on tap, I decided to sit on 1 bottle and trade the other (very good beer and I was pleased with aging just 1 when I learned of a 2nd release). Did an expanded trade that centered around Pugachev's Cobra for Barrel Aged Yeti (taking a shot at mine not being infected). Should pull down $4$ similar limited release
Regular tasting partners and I (here in CO) LOVED this one, not to mention the #4 Hammerhead barleywine. I have been having better luck finding #4. I am always in search of #3, and currently have 1 bottle in the cellar. LOVED IT!!!
I have owned two, thoroughly enjoyed one and traded one, have not gotten back their end of the trade yet.
