Here’s an old sample I dug up the other day: GlenDronach 1992, an Oloroso sherry butt released in November 2012 (batch 7).
GlenDronach 19 yo 1992 (57,8%, OB 2012, Oloroso butt #1123, 524 btl.)
Nose: very aromatic, in-your-face sherry, overloaded with prunes and dates, dark roast coffee beans, a mix of dark chocolate and raspberry / red berries. Faint notes of fresh paint. Demerara sugar. Big sherry, the juicy kind.
Mouth: as expected from the nose, very herbal, dry sherry. Tobacco leafs, leathery notes and wood. Dark chocolate, cloves. However there is a nice sweet-and-sour fruitiness underneath (raspberry again, juicy raisins-. Just a little burnt oak / roasted nuts in the background.
Finish: very long, on juicy fruits, chocolate and peppery oak.
It’s at the edge of becoming too tannic, but if you like heavy sherry (which I do, though I prefer more balanced examples these days), I think this was a rather excellent bottling.
Score: 90/100
