I have some very old Chartreuse bottles.. the green variety, with silver cap and tax label, and in ounces rather than metric. They seem to have a deeper, richer "chartreuse" green color than the relatively newer (but still dusty) bottles I have.
Any thoughts? It must be a different process/product because of the color difference, unless the newer bottles somehow faded due to sun exposure.
I have yellow Chartreuse, various vintages, and do not notice the difference there. However, I also notice that some mini bottles are 86 proof, and the other yellow are 80 proof. Did not know they made higher proof in the past, since I cannot find any info on this online.
So, two questions I guess!
Any Chartreuse buffs out there who know?
