They know exactly how many barrels they have left. Now, how much everyone else has left in stocks anywhere, that's the question they can't answer.
Problem is, you don't really know exactly how much is in a barrel... Until you need the barrel. I think they will be "out" of 20 year old S-W distillate in 2013 and 23 yr in 2016 IF they keep carefully meting it out the way they have been. of course... there's no guarantee that that's true.
For advertising's sake though, it's great to keep things ambiguous. Let all of us do the talking. Is it all BT now?? is there any S-W mixed in there??? Well maybe they--- With comments like these being flung around, The Van Winkles almost don't even need a full page ad in a magazine... just like Joe said.
My assumption is that as volume reduces in the tank, and a larger percentage of the remaining whiskey is exposed to air and allowed to oxidize, it continues to change. So every release from 07 or 08 (whenever it got tanked...?) would be "the same," except for the effects of air.
Something that WOULD be interesting to know for sure, is if the Saz 18 stocks came from the same source that PVWFRR and Hirsch rye came from.

As long as you have good whiskey you're not "unemployed", you're "Funemployed!!!"
