Scotch whisky is a world-renowned spirit with a wide range of flavor profiles that cater to diverse palates. One of the most defining characteristics of Scotch is whether it’s peated or un-peated. For enthusiasts and newcomers alike, understanding the difference between the two can enhance your appreciation of this iconic drink.
What Is Peated Scotch?
Peated Scotch gets its distinctive smoky flavor from the use of peat during the malting process. Peat is a dense, organic material formed from decomposed vegetation found in Scotland’s bogs. When burned, it produces a smoky heat that dries the barley and infuses it with unique phenolic compounds. These compounds, measured in parts per million (ppm), determine the level of smokiness in the whisky.
Flavor Profile of Peated Scotch:
- Smoky: Ranges from subtle campfire hints to intense, medicinal smoke.
- Earthy: Notes of wet moss, leather, or charred wood.
- Briny: Often coupled with maritime flavors, especially in coastal distilleries.
Famous examples include:
- Lagavulin (Islay): Known for its bold, medicinal smokiness.
- Ardbeg (Islay): Intensely peaty with a complex, oily texture.
- Laphroaig (Islay): A polarizing whisky with iodine-heavy, smoky characteristics.
What Is Un-Peated Scotch?
Un-peated Scotch skips the peat-burning step in the malting process, relying instead on other methods, such as hot air, to dry the barley. This results in a cleaner, more traditional grain flavor profile, allowing the natural characteristics of the barley, fermentation, and cask aging to shine.
Flavor Profile of Un-Peated Scotch:
- Fruity: Notes of apples, pears, citrus, or dried fruits.
- Malty: Warm, biscuit-like flavors.
- Vanilla and Spice: Enhanced by aging in oak casks, often American or European oak.
Notable examples include:
- Glenfiddich (Speyside): Light and fruity with a delicate sweetness.
- Macallan (Speyside): Known for its rich, sherry-cask influence.
- Glenmorangie (Highlands): Soft, floral, and elegant.
