When it comes to establishing provenance with UPCs, Wild Turkey may be one of the sleepiest of all because it's been a stable company and had continuously excellent product over the recent quarter century. Dawn's handy wallet UPC identifier (there really should be a catchy name for such a neat item "Pocket Bourbonifier"?) lists 2.
But, they seem to have used quite a few UPC prefixes. Here is a sampling of turkey bottles I have (mmm, that sounds kind of good, and it's only 9:30):
80433 - 1980s WT 8 year
82000 - 1995 and 2000 Kentucky Spirit
975830 - WT 12 year (box only)
80432 - Recent Russell's Reserve 101 and WT101
Why would Kentucky Spirit and WT 12 have different UPCs? Would a gift-box only offering commonly have a different code? Do premium products get their own prefix?
