I've been racking my brain to think of a "new" pour that left me really disappointed this year. The only one that comes to mind is HMcK1B (which as a 1B is inevitably variable).
Like everyone else, I'm disappointed that the secondary market makes it way more difficult to get some of the special releases. But looking back on 2013 - if my only disappointment was a less-than-stellar sb pick at under $35 - it was a pretty freaking good year! ECBP walked into my life, along with the GBS ETL (and the whole experience of picking that with many great folks on SB.com!), FR125, Bambi, and a few others.
Oh wait - American Spirit Whiskey . . . after hearing the tale of Michael J Flynn, I was expecting something truly stupendous, but that really let me down
