The concept behind Duncan Taylor’s The Octave collection is simple. Take something that is already good, transfer it into smaller Octave casks, mature it for more time. The aim? Amp up the aromas and flavours through a higher whisky to wood contact, triggering a bolder, more intense version.

So what did we find with this Glentaucheers?

Glentauchers 17 Year Old (8 May 2008 / 25 Aug 2025) Sherry cask 8546097 54.3% (Duncan Taylor – The Octave) ~90 GBP

Nose – How delightful! Cake, salty caramel, lots of rich fruity base notes, heavy mocha, ripe dark cherries, chocolate, and cream like a black forest cake, more coffee, toffee – delicious!
Palate – Very full, loads going on. There is an intensity with dark fruits, chocolate, old wood, malty, luscious fruits, and over-ripe nectarines. The dusting of pepper just adds another element – like a rich chilli chocolate ice cream
Finish – A big finish, treacle sweet
Water – Wow! Intense exotic fruits, durian to peach, then warmed pineapple

What a delight! We absolutely adored this expression. The extra “oomph!” from the Octave cask finish added complexity in a big, bold, beautiful way. Whilst we have no idea what it was like before the re-casking, here is what the folks at Duncan Taylor have to say :

Before Octivation

Apple strudel, creamy, raisins, custard creams, gooseberries.

After Octivation

Sherry, chocolate cake, spiced red fruits, clotted cream, white pepper.

What a complete treat! Curious about other Glentauchers experiences? Check out:

Technically, my whisky hosting for the Bombay Malt & Cigar evening in October 2025 was only a trio. And a mighty fine trio it was – starting with a lovely Lowland Glenkinchie; followed by a wonderfully balanced Speyside with a simply delicious Aultmore; closing with a beautiful Balblair from the Highlands.

However, we came back from the Whisky Show with a wee bonus dram that simply could not be missed!

Craigellachie 17 year (Jun 2008 / 25 Aug 2025) Madeira Wine Cask No 7547103 54% (Duncan Taylor – Octave)

Nose – Gorgeous! Dark, steeped fruit, Christmas pudding, sweet spices, big, bold, and beautiful
Palate – The Madeira element was unmistakable – in a wonderful way. Sweet and full- flavoured, it is quite powerful at full strength
Finish – Sweet, long, and chewy
Water – An absolute must! It opens the whisky up in the most marvelous way, loads of creamy aromas join the luscious dark fruits

This was a stunner – made even better with a generous splash of water. We found it quite autumnal – mature, full, and fabulous. A worthy dram to definitively close our whisky tasting and accompany the next section of the evening – the cigars.
