The Glenrothes Octave cask NO: 4939144 has aged for 9 years in oak casks, then spent the final 4 months in a sherry octave cask. This release of only 92 bottles, is bottled at a cask strength of 55.1% , non chill-filtered and naturally coloured.

For many years, Duncan Taylor Scotch Whisky Limited has experimented in the use of differing cask sizes for the maturation of single malt Scotch whiskies. This research stemmed from the simple premises that there is more interaction between the wood and spirit over a short period of time in a small cask than in a large cask, allowing for a faster melding of wood, air and alcohol.

To great delight, the spirit that resulted from this method of maturation demonstrated a depth of quality missing from a larger cask over a similar period of storage. It had become smoother, more balanced and was bursting with character, With its rough edges removed, the taste profile was changed dramatically, becoming akin to a whisky of a much more mature nature or vintage. It was polished, bright and sparkling with intensity.
