Tasted side-by-side with a 19-year ex-bourbon aged bottling. The color of the 18 is very slightly darker, but both are quite light in color. The nose on each is fairly indistinguishable from the other. If I had to say, I get the slighest bit more of brighter fruit on the 18. Both carry quite a bit of vanilla, coconut, pineapple, pear. The palate on both is fairly thin and understated. There's a bit more vanilla and spice on the finish of the 19, while the 18 finishes with a little dried fruit. They both seem to have smoothed out the slightly sour note I get from younger Glenmorangies. I would prefer both to be bottled at a higher proof, but both are nicely done and enjoyable whiskies.
