Smoky whisky isn't one flavour - it's a spectrum, built from three different techniques (smoked grain, a smoky cask, or smoke introduced after distillation) and, increasingly, fuels that have nothing to do with peat at all. This guide covers what actually makes a whisky smoky, what separates a good bottle from an overpriced one, and our curated picks under £100 - Scotch, Irish, Danish, New Zealand and English, all worth your money.

For the fuller story on how producers around the world are rethinking smoke entirely - Manuka wood, sheep dung, beechwood - read part one of our terroir series.

Smoke gets into whisky one of three ways, and they're not interchangeable - each gives a genuinely different result.

• Smoking the grain. The oldest and most common method. Malted barley is dried over a fire before it's ever mashed, and whatever's burning - peat, wood, heather - locks its character into the grain itself. That character carries through fermentation, distillation and ageing, softening a little at each stage but never fully disappearing. This is what most people mean when they say "peated."
• A smoky cask. Some whiskies never touch smoke during production at all. Instead, an unpeated spirit is matured in a cask that previously held something smoky - often an ex-Islay barrel - and picks up the character secondhand, from the wood rather than the grain. It tends to read as lighter and more of a top note than something built into the spirit's core. This character can also come from a heavily charred cask. 
• Smoking the finished spirit. The rarest method, and legally restricted to a handful of countries. Rather than smoking the grain or the cask, smoke is introduced directly into the whisky after distillation. Texas distillery Balcones is the clearest example, smoking finished spirit with Texas scrub oak - a punchier, more direct result than either of the other two methods.

All peated whisky is smoky. Not all smoky whisky is peated.

Peat is one specific fuel — decomposed plant matter, cut from waterlogged bogland and burned to dry the barley. Burning it releases phenols, the compounds behind that bonfire, iodine, medicinal character most people associate with "smoky Scotch." But a whisky can be smoky from wood, from cask influence, or from post-distillation smoking, with no peat involved anywhere in the process. "Smoky" is the broader category; "peaty" is one specific route into it.

Worth knowing too: the water has nothing to do with it, however often you hear otherwise. Smoke gets into whisky through the grain, the cask or post-distillation smoking - not the water.

PPM stands for phenol parts per million — a measure of how much smoke-derived compound is present in the malted barley before it's distilled.

It's the standard way distillers and drinkers talk about how intensely peated a whisky is likely to be.

A lightly peated whisky might sit around 10–15 PPM, giving soft, campfire-adjacent smoke. Laphroaig runs closer to 40 PPM, solidly into medicinal territory. At the extreme end, Octomore has been bottled past 200 PPM. Distillation and maturation soften the number considerably by the time it reaches the glass — so PPM tells you the starting intensity a distiller was working with, not exactly what you'll taste, but it's a genuinely useful comparison point between bottles.

New to whisky altogether? Our beginner's guide to tasting whisky covers the basics before you dive into smoke specifically.

Peat is decomposed plant matter compressed over thousands of years. Depending on where it's cut, it can bring notes of seaweed, tar, moss, and smoked meat. Islay malts like Ardbeg or Laphroaig deliver peat at full blast. Mainland styles like Highland Park or Benromach use it more subtly.

• Flavour profile: Earthy, medicinal, maritime, intense
• Commonly used in: Scotland (Islay, Highlands), Ireland, Japan

Instead of peat, some distillers use hardwoods like beechwood (Denmark) or Manuka wood (New Zealand) to smoke their malt. These bring lighter, less medicinal flavours—think BBQ embers, toasted nuts, or soft incense. Manuka-smoked whisky, like that from Thomson in NZ, often leans floral and spicy.

• Flavour profile: Toasty, sweet, aromatic

• Commonly used in: Denmark, New Zealand, USA

Rare but beautiful when done right. Heather or herb-smoked malt (now mostly revived in small-scale or experimental distilling) brings soft, aromatic smoke—less fire, more fragrance.

• Flavour profile: Floral, grassy, lightly smoky

• Commonly used in: Historic Highland traditions, experimental batches

Some whiskies get their smoky character not from the malt, but from the cask—usually an ex-Islay barrel that still carries smoky residue. These finishes tend to be lighter, more of a “smoky top note” than a core flavour.

• Flavour profile: Residual, subtle, integrated

• Commonly used in: Ex-peated cask finishes (e.g., Cotswolds Peated Cask)

Whether it’s peat from Islay or Manuka wood from New Zealand, smoke is a powerful tool in the hands of a good distiller. It can add structure, tension, and even elegance - if you know what to look for.
