I think Bunnahabhain's decision to up the ABV, ditch the chill filtering, and stop adding color to their single malts paid off in spades. The nose has a lovely rich, malty sweetness with a lot of floral character. The nuttiness makes me think there's a fair amount of sherry-cask aging, which would also explain the dark color. It's not complex, but it is mouthwatering. The palate confirms that it's sherry-aged -- raisins and fudge all day. It's sweet, but in an austere rather than decadent way, which distinguishes it from a Speyside dram. On the finish I get raisins, dates, and a tiny bit of brininess, with a long-lasting chest warming afterglow.
