I just came across this old thread and decided to do an inventory of the Leap Year Vanilla Mead from 2008. I still have 4 (wine) bottles left.
In the carton right next to it I have about a dozen bottles of Papazian's Barkshack Ginger Mead from 2007.
I know I even have older stuff. I may even have 1 bottle of mead from 1994. ; ' )
