It was Hector Henderson who originally brought the Caol Ila whiskies to the World in 1846. From there to now has not been an easy ride however. The distillery has endured numerous changes in ownership (it is currently owned by Diageo) and closures for all sorts of reasons. Since 1974, when demand for whisky recovered, it has been on a much surer footing though.
Classic Caol Ila. Terrific.
