While I haven't every top 2012 bourbon/rye yet (Eg. Stagg, WLW, VW's, etc.,), I can only comment on what I've had in 2012.
Favorite Independent Bottler/Blender: High West. While I loved the 21 & 16 year ryes, Rendezvous really knocked my socks off. They continue to push the boundaries, innovate, & I liked everything these guys put out: Campfire, Bourye, the list goes on & on
Favorite 2012 Bourbon: TPS John J. Bowman Barrel #45 (Runners Up: Vintage 17, CEHT Tornado, & FRSB OESO).
Favorite 2012 Rye: Sazerac 18 (Runners Up: High West Rendezvous & 16 year)
Favorite 2012 Blend: High West Campfire
2012 Whisky that most reminds me of drinking Chinese herbal medicine: Balcones Brimstone
Favorite 2012 Single Malt Scotch: Balvenie Tun 1401 Batch 3 (Runners Up: Talisker 18 & Ardbeg Uigeadail)
Favorite 2012 Tequila: Casa Noble 5 Year (Runner Up: Corrido Anejo)
Favorite 2012 Japanese Whisky: Hibiki 21 (Runner Up: Nikka Whisky from the Barrel)
Finally, thanks to all of you here on SB for your generosity, openness, & free exchange of knowledge! Happy New Year!
