I'll second the Talisker and Lagavulin already mentioned. Both are quite peaty, if you want to try something a little more along those lines than the Doublewood. I keep all three on hand. The progression in "peatiness" would go Doublewood - Talisker - Lagavulin. Laphroaig goes even one step further, but you really have to kind of work your way up through the progressively peatier single malts before trying the Laphroaig. Jumping in with both feet like that might be too much too soon.
