There has been a rumor for years that Barton was going to drop the BIB, either drop it all together or keep a 100 proof expression, but not as a BIB. If there was ever any truth to it, it hasn't happened.
About all Buffalo Trace plans to do with VOB is distribute it more widely.
Buffalo Trace has bottling plants at all four of its facilities (yes, even Bowman), but the one in Owensboro at the old Glenmore distillery is the largest and most modern.
I don't see any reason to start hoarding VOB, but I always have some in inventory.
