Glendronach 20 yo 1993/2013 (54.7%, OB, oloroso sherry butt, cask #16, 669 bottles) Colour: deep amber. Nose: rather a clean and zesty one, all on blood oranges, Demerara sugar, putty and a little olive oil. Some aspects make me think of Guyana rum - it does actually hint at some great aged rum. Very nice and very interesting. And clean. Mouth: not quite rum anymore - although I do find a wee molassy side - rather a big, nervous, orangey sherry with plenty of herbs and green spices. It's not a fat one. Also nice touches of cherries and bitters as well as a little lemonade. So, yeah, rather a 'nervous' sherry. Finish: long and even more citrusy and herbal. Lemon balm. Comments: a very pleasant variation on sherry, with grasses and herbs. SGP:661 - 88 points.
