Peat & Smoke: A Guide to Smoky Whiskies

Why Peated Whiskies Polarize – and Fascinate

Peated whiskies are like Marmite: you either love them or you hate them. There's hardly any in-between. For some, the intense peat smoke is the greatest thing, for others, it tastes like hospitals and bonfires.

But what exactly makes a whisky peated? Where does this characteristic taste of smoke, peat, and sometimes even iodine come from? And why are some whiskies only lightly peated, while others practically knock your socks off?

In this guide, you'll learn everything about peat & smoke – from the basics and PPM values to the world's smokiest whiskies. Whether you're a beginner or already a peat fan – you'll find all the answers here.

Peated Whiskies from Our Range

What is Peat?

Definition

Peat is partially decomposed plant material that has accumulated over millennia in bogs. In Scotland and Ireland, peat has been used as fuel for centuries – and this is precisely where the smoky taste in whisky comes from.

How is Peat Formed?

• Step 1: Plants (heather, moss, grasses) die
• Step 2: In oxygen-poor bogs, they only partially decompose
• Step 3: Over millennia, a thick layer of peat forms
• Step 4: Peat is cut, dried, and used as fuel

Why Peat for Whisky?

Traditionally, peat was used to dry malted barley. The smoke from the burning peat penetrates the barley, giving it (and later the whisky) its characteristic smoky flavor.

How Does Smoke Get into Whisky?

The Process Step by Step:

1. Malting

Barley is soaked in water and allowed to germinate. This creates enzymes that later convert starch into sugar.

2. Kilning (Drying)

The malted barley must be dried to stop the germination process. This is where peat comes in:

• Without Peat: Hot air dries the barley – no smoky flavor
• With Peat: Peat fire produces smoke that permeates the barley – smoky flavor

3. Phenols

Peat smoke contains phenols – chemical compounds responsible for the smoky, medicinal taste. These phenols remain in the barley and later in the whisky.

4. Distillation and Maturation

During distillation and cask maturation, the phenols change but are not completely broken down. The result: peated whisky.

PPM Explained: The Smoke Scale

What is PPM?

PPM = Phenol Parts per Million

PPM measures the concentration of phenols in the malted barley. The higher the PPM value, the smokier the whisky – in theory.

The PPM Scale:

• 0-5 PPM: Non-peated (most Speyside and Highland Whiskies)
• 5-15 PPM: Lightly peated (e.g., Highland Park, Talisker)
• 15-30 PPM: Medium peated (e.g., Bowmore, Caol Ila)
• 30-50 PPM: Heavily peated (e.g., Ardbeg, Lagavulin, Laphroaig)
• 50-100+ PPM: Extremely peated (e.g., Octomore, Bruichladdich Port Charlotte)

Important to Know:

PPM only measures the barley, not the finished whisky! Phenols are lost during distillation and maturation. A whisky with 50 PPM in the barley might only have 20-30 PPM in the finished product.

Why PPM Isn't Everything:

• Cask Maturation: Sherry casks can mask smoke, bourbon casks emphasize it
• Distillation: Slow distillation preserves more smoke
• Age: Older whiskies may taste less smoky
• Personal Perception: Everyone tastes smoke differently
