If you ever get a chance, try some of the bottlings from Murray-McDavid. These guys are negotiants who purchase aged barrels from different producers and then give them an extra year or two in different casks such as Chateau Lafite wine barrels or Port barrels. I'm currently working through a bottle of their Highland Park 15 yr finished in Chateau Lafite barrels. They also recently released a Bunnahabhain 13 Year Old finished in Port barrels. You can order these from KL Wines here in the Bay Area. Just do a search on their site klwines.com for "Murray McDavid".
