How to Date Your Vintage Bourbon

This is a small run down to help you determine the approximate year your bourbon was bottled.

  • Glass Date
  • Government Warning Labels
  • Metric vs Imperial
  • Printed Date Codes
  • Tax Strips
  • UPC 

Glass Dates:
This is generally the fastest way to determine an approximate bottle age.  Bottle manufacturers molded in a 2 digit year on the bottom of the bottle to represent the year the bottle was made.  


Government Warning Labels:
The federal government began requiring a health warning on all spirits starting in 1989.  However this would only be necessary for the US domestic market and does not apply to export bottlings.


Metric vs. Imperial:
US made bottles used the Imperial system (pint, quart, gallon) until 1980. Starting January 1st, 1980 all bottles were required to use the metric system (750ml, 1L etc)


Printed Date Codes:
In 1991 Wild Turkey began using dot matrix codes on their bottles to identify when a particular release was bottled.  Many other manufacturers followed suit throughout the 90's and early 00's.


Tax Strips:
Most bourbons and rye whiskeys had a tax strip seal over the bottle cap up until 1985.  Although not an official government item, many brands continued with "faux" tax strips which looked similar to the government issued strips.

Any bottled-in-bond tax strips will have the distillation year and the bottled year printed on it.


UPC Codes:
UPC Codes generally come in handy when determining between Stitzel Weller, Heaven Hill, and National Distillers.  Here's a list of the common UPC codes and their corresponding distilleries.
