Have five WTR 101, and seven 750's and three 1.75 of OWA (based on last year's "scare").
Given my O.C.D., I HAVE to have at least 2 of every bottle I like....that way I never open the "last" bottle of something.
Rye whiskey makes the sun set faster.
I'm not big into the whole "bunkering" thing. However, I do have one bottle stashed away of Knob Creek Single Barrel. It has some sentimental value as I helped choose the barrel. Also, I have two bottles each of Weller 12 and 2003 Evan Williams Single Barrel (both bottles from barrel #21). That's the extent of my "bunker".
At the moment.... nothing. I've drank what I had down, and I only have a bottle or two on hand these days. I can't justify tying up that much money anymore. If I get a hankering for something, I just go get a bottle, drink it, then get another as the need arises.
I would have to say (in answer to the thread's question) W. L. Weller Centennial, I think I have a couple of dozen of them.
I have the most bottles of what I like best: GTS.
While I have a good stock of BTAC, CEHT Tornado is the one bottle I have the most of. Since that one isn't coming back around again and my wife loves it as well, I bought a case of it.
