Who can guess? A buddy of mine was very lucky to get a bottle of this and gave me a taste! Here's a hint: It's 15 years old, American made, and can sell for $500+/bottle
Pappy Van Winkle -- 15 year.
Reasons: American made - Looks like a good whisk(e)y. Looks somewhat light for a 15 year but that may just be your camera/lighting. Rare & goes for $500 +/-? That is my 99% surefire guess.
Hope it was good none the less!
Post it up, man! Pappy is great stuff! I always keep my eyes peeled for some. Such a nice friend to give you that much 15yr! I'll forward you my address so he can give me some. But all in all, the Blanton's you got right next to it is just as good IMO, YMMV! Can't beat free PVW tho! Congrats!
