I have some Amphora Regular (brown), Sir Walter Raleigh, and Brindley's Mixture from 1996. (Don't know how it will taste, but I'll find out one of these days) Most of my cellar is from 2014, with a good portion from 2009.
I have some Butera tins from 2001 and Escudo from 2000. I also have some Dunhill Light Flake but I don't know what year it's from. There are some SG BBF and Squadron Leader tins from the 90's as well. Aside from that most stuff is probably from the last 3-5 years.
