The whisky from the distilleries on the other side of the island ie Bruichladdich & Bunnahabhain are much less peaty. I worked in Bruichladdich distillery (the most westerly of scottish distilleries) for 2 years so maybe a wee bit of favouritism. Black bottle is produced by the company that own Bunnahabhain (or it was) and is a blend of the Islays.
