The article is very helpful in narrowing down when our bottle of Chivas regal is from.
"Me and my husband were able to narrow down a bottle of Chivas, Regal Scott and whiskey blend all the way back to the days of when these bottles were measured in quarts. The Chivas regal scotch/whiskey blend has always been an upscale top shelf brand but when we found out what we really had, it was shocking, in the best way. We’ve narrowed one particular bottle down to the late 1960s which did in fact mention the Internal Revenue Service and the system in which was used to measure was quarts. Now we know exactly how much it is worth,” especially to the right buyer“. That is, of course, dependent on whether or not we would even want to part with this classic and then also to find out it was the exact same year that my husband was born in, 1967. This making it all the more valuable to us and also personal. Very cool stuff."
