If you can get hold of it, try Loch Dhu, its quite expensive but will be right up your street. they line the barrel with peat and then slowly burn it out. then add the whisky into the charcoal mess thats left. Its literally jet jet black.laphroig quarter cask (the 48% one.)
but i might try a blend (big gasp of horror heard) next called BIG PEAT which is a islay blend and has a good write up ,and then i'll try a islay single malt called SMOKEHEAD,lol.
