Glenrothes 1975 - 21 Year Old - First Cask - Single Cask 6051

Glenrothes is a much-loved Speyside distillery with a couple of notable claims to fame, namely that it was the keystone malt for Berry Bros & Rudd’s Cutty Sark blend from its launch in the 1920s, and in the 1990s it was the first distillery to specialise in vintage single malt releases. 

Founded in 1879, Glenrothes was expanded three times between 1963 and 1989, bringing the total number of stills to ten with a hefty production capacity of over 5.5m litres per year. The spirit seems to perform best with medium to long term maturation in sherry casks.

After sporadic old vintage releases in the 1970s under Highland Distillers (later fully acquired by Edrington), Glenrothes launched a core range of vintage single malts in 1994. A string of terrific vintage releases followed, including some astonishing 1960s casks. Although the vintage range has now been dropped, Glenrothes is remarkably consistent - just about any sherried release over 15 years old is likely to be terrific whisky.

The First Cask range was a prolific series of single malt whisky bottlings by the UK’s largest mail order wine company Direct Wines Ltd, owner of Laithwaite’s and The Sunday Times Wine Club. From the early 1990s until the mid-Noughties Direct Wines released dozens of outstanding single cask whiskies annually under the First Cask label, almost all of which were bottled at 46%.

These whiskies were not particularly highly sought-after on release, probably because they were only sold online through a wine club.  Back then, of course, it was not widely known that the casks had been sourced from Signatory Vintage, which would certainly have raised their profile among whisky fans. Nowadays, although still frequently excellent value at auction, the First Cask collection - which includes hundreds of long-aged whiskies from distilleries including Brora, Port Ellen, Ardbeg and Macallan - is finally getting the recognition it deserves.
