The Glenrothes is a single malt Scotch whisky, produced at the Glenrothes Distillery, beside the Burn of Rothes in the Speyside region. The Glenrothes is used in blended scotch whiskies such as Cutty Sark and The Famous Grouse. The Glenrothes is owned by Edrington Group.
The Glenrothes is mainly matured in Spanish ex-Sherry casks, and some ex-Bourbon casks. The Glenrothes is unique compared to other single malts in that, beginning in 1994, the bottlings are not determined by age but by vintage. Besides the signature line in which each year of production is bottled as one vintage, The Glenrothes is also sold as "Select Reserve", a recently introduced non-vintage line.
Special bottlings include "Single Cask" bottles, which are taken from one single cask of whisky from a particularly exceptional year. Single casks released include: 1966 Cask 1438, 1966 Cask 1427, 1967 Cask 6994 and 1967 Cask 6998. In the late 1980s, a few years years before Glenrothes Distillery decided to bottle The Glenrothes as vintages, some casks of whisky prior to 1974 were left to mature together.
These casks were bottled as a 30-year-old Glenrothes. Only 1134 bottles were produced. The house style is a warming, mouth-coating creamy spirit, with the classic Speyside "pear drop" character.
Tasting notes frequently also mention the descriptors "lemony", "grassy", "aniseed", "liquorice" and "toffee".[citation needed]
