Went to a Chateau Musar wine tasting earlier this year with a guy from the vineyard. At 10 quid a ticket I think I polished that value off in the first few minutes! We had some outstanding wine that night and rather a lot of it, more than worth the price of entry. His presentation was very informative too, had the entire family history of Chateau Musar and their ethos behind their wines and style of wine-making.
I'm a fan . . . it's not cheap, but is anything that's really good?
