I've bought several Clarendon recently from Grays vintage 2001-2003, personally I like them but friends and family not as much as they are a bit jammy / porty. However, all of my corks have been perfect unlike other wines of similar age that have all crumbled (I now own an AH-SO

). Exception being one of them that was corked (Blewitt Springs Grenache 2003) but fortunately I had a second bottle which was fine but a bit sad to see it going down the sink. :-(
I'm curious as to whether this is due to better quality cork or just better cellaring than the other wines. They could possibly have been re-corked but I don't believe so.
