Deep, woody, waxy and fudgy. Oodles of caramel, pollen and dark, wild honey. Spiced oranges, furniture polish, leather wax, dried herbs (rosemary?), perhaps a dash of turmeric. Very creamy and rounded, without any sharp edges or dominant aspects, really harmonious. Water brings out more of the mature components and increases both the waxy and the woody aspects.
Not too heavy on the sherry, but beautifully balanced between the influence of the refill butt and the clearly identifiable character of the spirit, which I love. I'd almost say it's 50/50 between cask and liquid, if that wasn't too tidy of an estimate. And it's all fully integrated; there's never a sense of the malt being "infused" with sherry as in many other such bottlings. Top notch.
Lovely tart/sweet/sour balance, good body, takes water well. Cinnamon, walnuts, a dash of mustard. Again heavy on the caramel, but not in any boring way; there's also plenty of deep tangy citrus and spicy herbal aspects to keep things lively.
Wild herbs and honeys, leather, juicy oranges. That lovely refill wood echo alongside a salivant salinity, with a mineral edge. Very long, like a good, 25+ Highland Park without the smoke. Count me in.
