There are certain expressions that remind you why you fell in love with whisky in the first place. The Glenmorangie Traditional 100 Proof, a 10 Year Old Highland single malt bottled at a commanding 57.2% ABV, is one of them. This is a bottle that has become increasingly difficult to track down — a discontinued expression that once sat quietly on shelves and now commands serious attention from collectors and drinkers alike. At £299, you are paying a premium, but you are also buying a piece of Highland whisky history that is no longer being made.
What makes the Traditional 100 Proof so compelling is its confidence. The "100 Proof" designation refers to the old British proof system, translating to that robust 57.2% ABV — a strength that was once far more common in everyday bottlings than it is today. This is Glenmorangie without compromise, without the dilution that characterises so many modern releases. The full cask strength character of the spirit is on display here, and for a 10 year old expression, it carries remarkable depth and composure at that strength.
As a Highland whisky, this expression sits squarely within a tradition of approachable yet layered single malts. The Highland region has always produced whiskies that balance fruit-forward sweetness with a gentle spice, and the Traditional 100 Proof is no exception — though it delivers those characteristics with considerably more intensity than a standard 40% bottling ever could. The additional ABV acts as an amplifier, bringing texture and weight that reward patient, attentive drinking.
Tasting Notes
I am not publishing formal tasting notes for this particular bottle at this time. I want to revisit it in a proper structured session before committing nose, palate, and finish to print. What I will say is this: at 57.2%, expect presence. This is not a whisky that whispers. The higher strength pushes flavour delivery into territory that standard expressions simply cannot reach, and a few drops of water open it up considerably. If you know Glenmorangie at its standard strength, imagine that profile with the volume turned up and a broader, more viscous mouthfeel underneath it.
The Verdict
I am giving the Glenmorangie Traditional 100 Proof an 8.3 out of 10. This is a genuinely rewarding Highland malt that earns its score through sheer integrity of character. The higher ABV gives it a dimension that many age-statement whiskies at standard strength lack, and the 10 years of maturation provide enough structure to keep everything in balance. The price is steep — there is no getting around that — but discontinued expressions of this quality only become harder to find, and this one drinks well above what you might expect from a decade-old whisky. It is not a perfect score because the premium reflects scarcity as much as liquid quality, and I would have liked to see an official outturn or vintage detail. But as a drinking experience, it is first-rate.
Best Served
Neat, in a Glencairn, with patience. Let it sit for five minutes after pouring. Then add a small splash of room-temperature water — no more than half a teaspoon — and let the ABV settle. At 57.2%, the water is not optional; it is essential to unlocking the full range of what this whisky has to offer. A classic Highland Highball would also work beautifully if you are feeling generous with a bottle at this price, though I suspect most owners will prefer to savour it slowly.
