The green Bottled in Bond strips were discontinued starting December 1, 1982.
Below is an example of a bonded tax strip (click to enlarge). – Starting in 1945, the words “Series” and “111” appear below the eagle in the center of red strips.
There are several clues to assist in identifying the year and distillery of whiskey bottles.Most bottle manufacturers molded the year into the glass at the bottom of the bottle in 2-digit format.Bottled in bond tax strips are green; non bonded tax strips are red and do not show the years.Blue tax strips were for export out of the US only, but not all exports used blue strips.Sometimes you’ll find two different 2-digit dates in the same bottle.
Generally the earlier date refers to the year the bottle mold was created, and the latter is the year the bottle was made.Some bottles produced during the transition will show both metric and ounces.Incidentally, the term “fifth” for a bottle of liquor comes from the fact that the standard size for many years was 1/5 gallon.– Prior to 1973, green bonded strips denoted the size of the bottle, for example 4/5 qt, on one end of the strip. Below is an example of a 1945-1960 style strip (click to enlarge).– In January of 1961, the “Series 111″ was changed to “Series 112″ on red strips and the size of the bottle no longer appeared at the end of non-bonded strips (except for mini bottles, which were excluded).If your bottle shows these words, it was probably bottled between 19.
