The Scapa was surprisingly light but surprisingly rich for it's all it's lightness. Very complex, and very easy to drink a *lot* of. (I seen to remember declaring Dr. Seuss to be The American Robert Burns before launching into a recitation of The Lorax.)
Drinking the Ardbeg 17 was like being forcibly held down in a tidal pool on the Isle of Lewis. Suffice to say, I loved it.
