Thompson Brothers have been quietly building one of the more interesting portfolios in independent Scotch whisky, and their Williamson Blended Malt Over 12 Year Old is a bottle that tells you a lot about where they're putting their energy. For the uninitiated, 'Williamson' is one of those open secrets in the whisky world — a name that independent bottlers use when they can't name the Islay distillery on the label. You know the one. If you've spent any time around peated single malts, the name does the work for you.
What makes this release noteworthy is the format. This is a blended malt, meaning Thompson Bros have married peated Islay malt with components from elsewhere to build something that's more than just a cask pick. At 50% ABV and with a minimum age of 12 years, it sits in a sweet spot — enough maturity to round off the sharper edges of young peat, enough strength to carry real flavour without needing a PhD in cask-strength survival techniques. It's bottled at a proof that actually respects the spirit rather than chasing a number.
What to Expect
Without confirmed tasting notes to hand, I'll speak to the style. A 12-year-old blended malt built around Islay peat at 50% should deliver a well-integrated smokiness — the kind where the peat has had time to settle into the wood influence rather than simply shouting over it. Thompson Bros have form here; their blending tends toward balance rather than brute force. Expect the peat to share the stage with malt sweetness and whatever the secondary components bring to the party. This isn't a peat bomb. It's a conversation.
At £105, you're paying a premium over your standard distillery 12-year-old, but you're also getting something that a big distillery won't give you — a blender's interpretation, bottled at natural strength with no chill-filtration or colour adjustment. Thompson Bros don't cut corners on presentation or integrity, and that matters when you're spending north of a hundred quid.
The Verdict
I rate this an 8 out of 10. It's a confident, well-constructed blended malt from a bottler who understands what they're doing with Islay spirit. The 12-year age statement provides genuine reassurance — no guesswork about what's in the bottle — and the 50% ABV is the kind of decision that shows respect for the drinker. Thompson Bros continue to earn their reputation, and this Williamson release is exactly the sort of bottle that justifies paying attention to independent bottlers rather than defaulting to the usual suspects on the shelf. If you like your peat with some polish, this belongs on your shortlist.
Best Served
Pour it neat first and give it ten minutes to open up in the glass. If you want to add water, go carefully — a few drops will spread the smoke out and bring the malt character forward, but this is already at a very drinkable strength. Personally, I'd take this one slowly after dinner, maybe alongside a hard cheese or some dark chocolate. It's not a cocktail whisky, and it doesn't need to be.
