Glencadam’s 15 year-old expression, like most of its releases, is aged exclusively in ex-bourbon casks to retain the distillery character. The whisky is not chill-filtered and has no added coloring, and is bottled (now) at 46% ABV. It was named Whisky of the Year by Ralfy in 2017, which caused a supply crunch.
GlenDronach’s 21 year-old bottling from the official distillery lineup is aged in a combination of PX (Pedro Ximenez) and oloroso sherry casks. (Note that is “aged” not “finished” – this whisky sat for a full 21 years in barrels previously containing sherry.) Hilariously enough in the current political climate, this whisky is not in fact named after the British Parliament, but rather for the “parliament” of rooks that nest in the trees overlooking the distillery. It is bottled at 48% ABV and without chill filtration or added coloring.
Dailuaine is known as a component in Johnnie Walker blends, which is where the vast majority of the output from the distillery’s three wash and three spirit stills goes. This particular 16 year-old was matured in ex-sherry casks, although I can’t find any details (Full-term maturation? Finish?). Diageo is, as usual, tight-lipped about production details. Bottled at 43% ABV, probably chill-filtered, and likely colored.
There is a wild raging debate on the Internet about the actual source of Alexander Murray & Co.’s big-age, low-price malts. Some rumors suggest that the majority of the company’s barrels come from Tullibardine (a whisky chameleon of sorts), while the company has definitely bottled Macallan before, and is reported to have contracts with both Diageo and Edrington.
Wolfburn Aurora was released in 2016 from 3 year-old Wolfburn malt aged in a variety of casks. Reportedly, this means 40% of the whisky was aged in second-fill quarter casks, 40% in first-fill ex-bourbon barrels, and the remaining 20% in first-fill Oloroso sherry hogsheads.
The GlenDronach 18-year is named after the 1826 founder of the distillery, James Allardes. It is aged for 18 years exclusively in Spanish oloroso sherry casks, and bottled at 46% ABV without chill-filtration or added coloring. This has more deep, dark, concentrated dry fruit than I’ve ever experienced in a single malt. I’m not sure that’s actually a good thing. …
Yet another of Diageo’s stable of “blending fodder” – some malt distilled at Lochnagar finds its way into Johnnie Walker (Blue, in particular) and Vat 69, but the majority of Diageo’s smallest distillery (smallest in output, that is) is now bottled as a single malt, including a Distiller’s Edition finished in Moscatel casks and an NAS Selected Reserve edition aged in sherry casks.
The 14-year Rich Oak uses an experimental finishing technique that appears to have been deemed enough of a success to launch it in 2010, although it still has not ventured Stateside. … Standard ex-bourbon aged Glenfiddich is re-casked after 14 years into a mixture of new Spanish oak and new American oak, for a brief finishing period of “up to” 12 weeks. This is apparently the first time any single-malt scotch has been finished in new Spanish oak.
Glenturret is probably best known as the site of the Famous Grouse Experience, a tourist attraction and visitor center for blended scotch The Famous Grouse. Both the brand and the distillery are owned by Highland Distillers (The Edrington Group), which also owns The Macallan and Highland Park. The vast majority of the Glenturret distillery’s single malt output goes into various Grouse blends, although it has also been bottled as a single malt for some time.
Here we have something new. Whisky is (sort of) distilled beer, right? And most (almost all) beer contains hops to some degree. So why not age whisky in casks that previously held heavily-hopped India Pale Ale style beer? … a specially-brewed IPA ale using Challenger hops was aged for 4 weeks in used Glenfiddich American Oak barrels, and then emptied and used to finish Glenfiddich single malt for 12 weeks.
