No, mine is not a special bottling to the best of my knowledge. I picked this up at a Montgomery County liquor store, mostly because I wanted to compare it to my new PHC, which I am absolutely loving, and is reportedly about the same age and roughly the same proof. The PHC is superior with its delightful creaminess, but not by that much. I will have to check out that Midway place sometime when I'm close by.
I found a solid single barrel store offering of this at Old Town in Louisville. It is a collab with Doc Crowes restaurant. Good stuff.
Having my second pour right now, this is an excellent Bourbon!
I just picked up a couple of bottles of the Midway Liquor barrel selection of McKenna and it is fantastic! Even better than the standard one I picked up earlier. I have compared it against nearly every bottle I have open at the moment, and with the exception of PHC version 7, it was equal or better than all of them. This is the second best bottle I've purchased all year. Two very enthusiastic thumbs up!
On a related note, check out the Midway Blantons barrel they have. I've only had two bottles of Blantons in my bourbon journey, and although I consider it a decent pour, it always seemed like a flatter more expensive version of ETL. Their barrel is much better than that, and I'm looking forward to comparing it against my lineup soon.
