There are independent bottlings that catch your eye, and then there are those that make you sit up and pay proper attention. The Tamdhu 2009, bottled by Gleann Mòr as part of their Rare Find series, falls squarely into the latter camp. A 16-year-old Speyside single malt finished — or possibly fully matured — in Barbadillo oloroso sherry casks, bottled at a commanding 51.7% ABV. At £102, it sits in that increasingly contested space where independent bottlers must justify themselves against official distillery releases. This one does.
Gleann Mòr have built a quiet reputation for sourcing casks that tell a story, and the choice of Barbadillo cooperage here is notable. Barbadillo, based in Sanlúcar de Barrameda, is one of the oldest and most respected sherry houses in Andalucía — their oloroso casks tend to impart a drier, more structured influence than some of the sweeter sherry wood you encounter in the Scotch world. Paired with Speyside malt that has had sixteen years to develop, the combination promises something with genuine depth rather than the syrupy sherry-bomb approach that has become all too common.
At 51.7%, this sits at natural cask strength or very close to it, which I always welcome. It means you are getting the whisky as the blender intended, without the dilution that can sometimes flatten character. A few drops of water should open this up considerably, and I would encourage patience with it — let it breathe in the glass for a good ten minutes before forming any judgements.
Speyside malts of this age, when treated to quality sherry wood, tend to develop a wonderful interplay between the orchard-fruit sweetness inherent to the region and the darker dried-fruit and nutty qualities that oloroso imparts. The 2009 vintage places the distillation squarely in a period when many Speyside distilleries were operating at high capacity, so cask selection becomes the defining factor — and Gleann Mòr appear to have chosen well.
Tasting Notes
I will update this section with full nose, palate, and finish notes following a more extended tasting session. First impressions suggest this rewards time and attention rather than quick judgements.
The Verdict
At £102 for a 16-year-old cask-strength Speyside single malt in quality sherry wood, this represents genuinely strong value. Official distillery releases of comparable age and strength routinely command £130 or more, and the Barbadillo oloroso influence adds a layer of specificity that generic 'sherry cask' bottlings rarely achieve. I am scoring this 8.4 out of 10 — a whisky that delivers on its promise and offers something distinctive within a crowded category. The Gleann Mòr Rare Find series continues to impress, and this bottling is one of the stronger arguments for exploring independent releases rather than defaulting to brand loyalty.
Best Served
Neat, in a Glencairn, with a few drops of still water added after your first nosing. The cask strength rewards controlled dilution — start without water, then add sparingly until the spirit opens up. This is not a whisky for cocktails or heavy mixers; it deserves your full attention. A quiet evening, no distractions, good company optional.
