I tasted the Isle of Jura again tonight. I tasted it neat, then slightly diluted, then again with a cube of ice melting in it.
I found the whisky to be approachable, and unassuming. There is a definite hint of sherry both in the nose and on the tongue, and the finish brings in hints of peat and saltiness. It is a very decent whisky, not overpowering like some find the Laphroaig or Lagavulin. It may not be the first bottle I reach for, but it is a respectable whisky for those who enjoy a smoother, less spicy/peppery/peaty dram.
After tasting it again, I lit up a Rocky Patel 1990 Vintage and poured myself a glass of Isle of Jura. The cigar extinguished most of the taste that WAS there, but it was still pleasant to drink.
