Picked up an L26 release of Bollinger Sp Cuvee last week at CostCo to give it a go. Noticed the specific markings on the cork as you can see below.
Anything in regards to detailed blend information in Champagne is welcome. Though in this case its not viewable until you remove the capsule of course.
I would also note that 2022 is one off the normal ~3 vintage delta from L#. Though of course that is no rule. I know some blends can be closer to 50/50 of two current vintages with the normal balance being from library wines.
