Ardmore 20 yo 1968/1989 (58.4%, casks #5490 + 5491)
An older bottle with an already hefty reputation... Colour: gold. Nose: ooft! This Ardmore sooty / lemony profile is there but it’s draped in a stunningly dense syrup of waxes, herbal liqueurs, precious hardwood resins, cough mixtures, medicines, umami cooking stocks and some kind of smoky truffle honey. Goes on with creme de menthe, cupboard spices, treacle and a waxiness that has an almost fudge-like consistency. You could stand a spoon in the glass I expect. With water: gets fresher with these notes of lemon, fabric, cereal, straw, earth, mushroom, wet leaves, tobacco, pine cones and petrichor. Mouth: just brilliant! Pure, old school, majestic, textural malt whisky. Mineral oils, waxes, hessian, camphor, soot, phenols, lemon rind, tar extract, herbal medicines, fennel seeds, mint tea, orange marmalade. Thrilling and deadly whisky! With water: the kind of whisky that only seems to get more textured and fat and swollen with water. Gloopy mineral oils, mechanical notes, thick phenolics, soot, hardwood resins, herbal extracts and wee hints of old sweet dessert wines. Finish: long, earthy, tarry, sooty, medical, peaty and with this big salty honey note throughout. Utterly brilliant. Comments: This really harkens back to the kind of peat and herbal profiles you could find in many pre-war malt whiskies. A stellar wee Ardmore that almost tastes like some kind of baffling old school 1950s Laphroaig, and yet, always remains its own thing. What a whisky!
SGP: 575 - 93 points." (Angus)
Ardmore 20 yo 1968/1989 (58.4%, Casks #5490-5491) Five stars Colour: gold. Nose: more or less as if you put your nose over an old chimney at first nosing, reminding us of some old Ardbegs (1974/1976). Actually, this baby could have been an old Ardbeg that would have lost 50% of its peatiness. There are also whiffs of leather, manure and rotting fruits, a bit in the style of some old Ben Nevisses if you see what I mean. The whole makes for a very interesting and unusual combination once again but warning, it’s hot whisky! So, with water: my oh my! An avalanche of herbal notes that are utterly superb. We would need pages to list them all. Mouth (neat): bang! What an extreme whisky, peatier now but also immensely rooty and earthy, and fruity as well. There are ripe, juicy peaches all over the place as well as quinces and maybe mirabelles (those yellow plums that abound in Alsace and that we like to distil!) Brilliant so far. With water: terrifyingly earthy and rooty, with also bags of bitter oranges and quite some pepper. Even quite some wasabi, which should tell you how big this is, even at +/-45% vol. Finish: very long and very peppery, ala 20yo Talisker OB. Comments: quite a monster, not for the fainthearted. A beauty but that didn’t come unexpected. SGP:466 - 93 points. (Serge)
