There's something irresistible about a secret Islay. The moment you see those two words together on a label — 'Secret Islay' — you know you're dealing with a whisky that wants to be judged on what's in the glass, not the name above the door. The Supernova Secret Islay 2009, bottled by DH Global Spirits at 15 years old and a muscular 57.5% ABV, is exactly that kind of dram. No confirmed distillery, no marketing gloss — just cask-strength Islay single malt that's had a decade and a half to find its voice.
And what a voice it is. At fifteen years, this sits in a sweet spot for Islay malts. It's old enough that the raw peat aggression of youth has had time to integrate and develop complexity, yet young enough to retain genuine power and coastal character. The 57.5% strength tells you immediately that DH Global Spirits had the good sense to leave this un-meddled — no chill filtration, no dilution to some approachable 43%. This is whisky for people who actually want to taste whisky.
The 'Supernova' name suggests intensity, and the strength certainly delivers on that promise. Islay at cask strength is not for the faint-hearted, but fifteen years of maturation provides a counterweight that keeps everything in balance. Whatever distillery produced this — and the Islay cognoscenti will have their theories — the spirit quality is clearly first-rate. You don't get to fifteen years in good nick without strong foundations in the wash and spirit stills.
Tasting Notes
I'll be straightforward here: I want you to discover this one for yourself. What I will say is that at this age and strength, you should expect the full spectrum of what makes Islay single malt one of the great styles of Scotch whisky. The interplay between peat smoke, maritime influence, and the slow work of oak over fifteen years is precisely what draws collectors and enthusiasts to independent bottlings like this. Add water gradually — at 57.5%, this rewards patience and opens up in stages.
The Verdict
At £160, the Supernova Secret Islay 2009 occupies a competitive space. You're paying for fifteen years of age, cask-strength bottling, and the genuine quality of Islay single malt from a respected independent source. Compared to official distillery bottlings at similar age and strength — which increasingly command north of £200 — this represents fair value. The mystery of the source distillery is part of the appeal: you're buying on flavour, not on brand recognition, and that's rather refreshing in a market increasingly driven by labels and limited editions.
I've given this an 8.1 out of 10. It's a confident, well-matured Islay cask-strength malt that delivers exactly what it promises. The age has brought integration and depth, the strength brings honesty, and the overall package is one I'd happily return to. It misses the very highest marks only because, without confirmed provenance, it's difficult to place it in a broader context — but taken purely on its own merits, this is a thoroughly rewarding dram.
Best Served
Neat first, always, to meet it at full strength and understand what you're working with. Then add water — a few drops at a time with a pipette if you have one. At 57.5%, this will open up considerably with dilution, and finding your preferred ratio is half the pleasure. A classic Islay Highball with good soda water works beautifully if you're in the mood for something longer on a warm evening, though I'd be reluctant to mix away a whisky at this price point too often. This is primarily a contemplative pour — give it time and attention, and it will repay both.
