Whisky Oban 10 Year Old The Celestial Blaze. From Diageo's much-anticipated Special Releases comes a bottle of Oban 10 Year Old that was aged in refill and new American Oak, before further double maturation in ex-sherry and Amontillado seasoned casks. Interesting stuff from a bottle dubbed ‘The Celestial Blaze’, a reference to the lights of the Aurora Borealis that can be seen from Oban Bay, and how legend had it that the vivid blaze of light was driven by a celestial being.
