This expression is a bit better than the 12 year and bit less so than the 18 but is certainly the right price for quality.  I think if you can find the older dumpier bottles, buy them, they are also that much better then the new bottle.

The smooth smoke with almost no hint of peat is really good. I adore Highland Park as a great go-to bottle any time just need some whisky and I want falt out good stuf without any real ...erm....style/trend.

When I nose this I think of black grape juice. Like a sophisticated Welch's if you will. But the nose also has plumbs and coal smoke as well. Very sweet yet bitter fruits on the palate. It finishes nicely with smoke and soot. B/B+

Side note: I'm having the "round dumpy" older bottles from the early 2000s and I find these to be more enjoyable compared to the new flask type bottles. Agreed with Dave on buying em if you see em. 

n: caramel malt, burnt paper smoke, light bit of sea spray. Marsh grasses, raisin mix, and a hint of mint gum. Nice nose with fruit and a dry smoked-salt nose (like a BBQ meat rub).

t: caramel and golden raisin/prune fruit mix with smoke and grey seasalt appearing in the middle. It has a nice smoke thats soft and savoury (sweet & salty). Sour yellow cherry. Ashy earthy smoke. Grilled tangerine. F;at finish is more of the wet earthy/grass flavor with dry wood.

Note:  Round Shoulder version

n:  funky sherry

p:  Stale water with sawdust
