Thirty-one years in oak. Let that sit with you for a moment. The Benriach 31 Year Old from the Thanes Series — subtitled Menteith, the first act of their Macbeth-inspired collection — is the kind of bottle that demands you slow down before you even crack the seal. At 53.1% ABV and over three decades of maturation, this is Speyside whisky operating at a level most distilleries only dream about.
Benriach has always been one of those Speyside distilleries that punches in a different weight class. They're not afraid of experimentation — peated expressions, triple distillation trials, unusual cask finishes — but when they go long on age, they tend to let the spirit do the talking. That's exactly what's happening here. The Thanes Series ties each release to a character from Shakespeare's Scottish Play, and Menteith — the reluctant thane, the quiet observer — feels like an apt namesake for a whisky that carries its age with restraint rather than shouting about it.
At 53.1%, this hasn't been watered down to some gentle sipper. That's a deliberate choice and one I respect. After 31 years, you'd expect a whisky to have pulled enormous character from the wood, and bottling at cask strength means nothing gets lost in translation. You're tasting exactly what the distillers tasted when they made the call to bottle. For a whisky at this age and strength, the balance between spirit character and cask influence is the entire game — and at £730, you're paying for the decades of patience it took to get that balance right.
Tasting Notes
I won't fabricate specific notes I don't have confirmed data for, but here's what you should expect from a 31-year-old Speyside at cask strength: this is a whisky where time has done the heavy lifting. At this age, you're looking at deep integration between spirit and oak. The high ABV suggests the cask was active and generous throughout those three decades. A few drops of water will open this up considerably — don't be afraid to experiment. The long maturation at Speyside's relatively mild climate means slow, steady extraction rather than the aggressive wood influence you'd get from warmer warehouses.
The Verdict
Is it worth £730? That's always the question with ultra-aged whisky, and my honest answer is yes — with a caveat. This isn't a bottle you buy for Tuesday night. This is an event pour. The 31-year age statement is genuine, the cask strength bottling shows confidence in the liquid, and the Thanes Series concept gives it a collectability factor that frankly matters at this price point. I'm giving this an 8.5 out of 10. It loses half a point because at this price I want confirmed provenance on the cask type, and another half because the Thanes Series packaging, while handsome, adds a premium that's partly theatrical. But the whisky itself? Outstanding. Benriach at 31 years old and cask strength is a rare thing, and this delivers on the promise of what decades of patience should taste like.
Best Served
Neat, in a Glencairn, at room temperature. Give it ten minutes in the glass before your first sip — a whisky this old needs air to unfold properly. Add water sparingly, a few drops at a time. At 53.1% there's headroom to bring the ABV down gradually and discover what opens up at each stage. This is absolutely not a cocktail whisky. Pour two fingers, sit down, and give it the time it spent waiting for you.
