Some tasting notes
Johnnie Walker Gold: I got a 50ml minibottle. This blend is dominated by Highland malts. It noses like the Dalwhinnie 15 with lots of light flowers, grass, and malt. But the finish doesn't have even the slight smokiness that the Dalwhinnie does--it stays with malt and fruit, rather like the Glenlivet 12, but not so much fruit.
And like the Glenmorangies, is a bit sharp without water, but just a couple of teaspoons makes it super-smooth: "buttery" as Tyson put it.
Something weird: the first few sips, I get a strong herbal note in the middle--parsley? But I can't pick it up at all by the time the dram is half gone!
That bottle of Macallan 18 I got was the 1986 "vintage". This seems a little heavier on the sherry than I remembered, but it is still very smooth and complex. Almost like a dessert!
