This is part of the 2010 single cask series.
GlenDronach 20 yo 1990 (57,9%, OB 2010, oloroso sherry butt #2621,
Nose: quite a fragrant kind of sherry. Hints of sweet honey and oak polish. Red mosto (grape juice) and sour oranges. After that, a very classy nuttiness starts to grow stronger (walnuts, some roasted coffee beans, almonds). Evolves on dark chocolate. There are undertones of matchsticks as well, but they’re actually quite nice and seem to come and go (with some water they simply disappear). Some mint. Hints of leather. Quite complex!
Mouth: starts fruity (figs, dates) with hints of cherry liqueur. Again (clean) matchstick notes. Old oranges. Nice mocha and chocolate truffle. A few drops of water highlights walnuts and almonds.
Finish: nice finale on coffee and nuts. Quite long.
This one actually has the lightest colour of the whole series (together with the 1978). The 1989 is also very good - about the same price.
This sounds like the pick of the bunch from this series, it's an appetising colour. Very rich.
I've sampled the Revival Sherry Cask and thought it was very promising.
