What makes a whisky “smoky”? – Everything about peaty whiskies and aromas

Smoky whisky delights with its unmistakable aroma, reminiscent of campfires, earth or even medicinal notes. Peaty whiskies have a particularly strong character and are a highlight for connoisseurs who want to indulge in intense and complex aromas. But how does this smoky taste come about, what role does peat play in the production process, and which whiskies are known for their smokiness? This article provides a comprehensive insight into the world of peaty whiskies.

How does the smoky taste in whisky come about?

The smoky taste of a whisky is created during production by the use of peat . Peat is a fossil fuel that is found in moorland landscapes and is created by the decomposition of plants over thousands of years. In whisky production, peat is burned to dry the barley after it has been germinated. The barley absorbs the aromatic substances from the peat smoke.

The intensity of the smoky aroma depends on the duration of drying in peat smoke and the composition of the peat. The longer the barley remains in contact with the smoke, the more intense the smoky aromas will be in the resulting whisky.

The chemical basis: phenols

The smokiness of a whisky is caused by chemical compounds called phenols . These are released when the peat is burned and settle on the barley grains. During the distillation and maturation, these compounds remain and provide the characteristic smoky notes.

aromas caused by phenols

The flavors in a smoky whisky are varied and can be influenced by the circumstances. Common flavors include:

• smoke and ash
• earthy-mossy notes
• Medical tones, such as iodine or antiseptic aromas
• tar or charred wood

The intensity of these aromas depends not only on the peat content, but also on the length of barrel storage and the type of barrel used for maturation.

Regions known for peaty whiskies

Not all whiskies have a smoky character, as the use of peat varies from region to region. The Scottish island of Islay and parts of the Highlands and Scottish islands are particularly well-known for peaty whiskies.

Islay – The Heart of Peaty Whiskies

The island of Islay, one of Scotland's whisky regions, is known worldwide for its highly peaty and smoky whiskies. Distilleries such as Laphroaig , Ardbeg and Lagavulin are based there and offer whiskies with intense, smoky flavors. The region's high peat content, as well as the harsh climate and salty sea air, give Islay whiskies their unique character.

Highlands and Islands

The Highlands and Scottish islands also produce peaty whiskies, but usually with a milder smoke profile. Brands such as Talisker from the Isle of Skye or Highland Park from Orkney often combine peaty notes with sweet, spicy or fruity flavors, making them versatile and accessible.

Measuring smokiness: PPM as a guide

The intensity of a whisky's smokiness is measured in PPM (Parts Per Million) , a value that indicates the concentration of phenols. The higher the PPM value, the stronger the smoky taste.

• Mildly smoky : 1-10 PPM (e.g. Glenkinchie, Balvenie Peat Week)
• Medium smoky : 10-30 PPM (e.g. Highland Park, Springbank)
• Intensely smoky : 30-50+ PPM (e.g. Ardbeg, Laphroaig)

It is important to note that the PPM value is only a rough guide. The perception of smokiness is influenced by other factors such as barrel storage and alcohol content, so a whisky with a high PPM value does not necessarily have to taste more smoky.

Peaty whiskies: enjoyment and versatility

Smoky whiskies are not only an experience on their own, but are also versatile – whether in combination with food or as an ingredient in special cocktails.

Suitable dishes for smoky whisky

The intense aromas of a peaty whisky harmonize perfectly with strong or smoky dishes. The best combinations include:

• Grilled meat, such as steak or lamb
• Seafood, especially oysters or smoked salmon
• Dark chocolate that combines sweet and bitter nuances with smoky aromas

These pairings enhance the aromas of the whisky and offer a well-rounded taste experience.

Smoky Whiskeys in Cocktails

Peaty whiskeys are also appreciated in mixology. One example is the Smoky Old Fashioned , which combines the smoky notes of the whiskey with sugar, Angostura bitters and orange peel. The Penicillin cocktail - a mix of peaty whiskey, ginger, honey and lemon - is another highlight that complements the smoky flavour in an interesting way.
