The Octave Glentauchers 2008 10years cask 8517929 Single Cask Scotch Whisky 750mL

• This is a single-malt Scotch from Glentauchers, distilled in 2008 and released under the Octave bottling programme by independent bottler Duncan Taylor.
• “Octave” refers to a finishing regime where the whisky — after primary ageing — is finished in a smaller “octave” cask (much smaller than a standard cask). This increases wood-spirit contact and tends to intensify or alter the wood-derived character of the whisky.
• The bottle you mention (53.5% ABV, 750 mL) seems to match some of the bottlings from this line (some are 700 mL — many Octave releases are small-batch / limited releases).
