While the champagne domaines continue to improve their practices regarding providing detailed label info, I continue to find new releases that do not include base year and disgorgement date anywhere other than in a code etched on the bottle.
Our resident champagne experts have posted “secret decoder rings” for specific bottlings in various threads but I haven’t seen a central resource where these are collected for easy reference.
Inclusion of this info in TNs is incredibly helpful and, of course, if you want to use the guidance you have to be able to ID your bottle.
If there is already a compilation of the code formats, I’d love to know about it. If there is not, perhaps this thread can be a central place for collecting the information.
If it’s helpful, I can make an effort to collect info from posts in this thread and update this initial post with a summary chart.
