Heavily peated whisky is a term used to describe a style of whisky that has a high level of smokiness. Peat is a fuel source that is used to dry malted barley during the whisky production process. When the barley is exposed to peat smoke, it absorbs the smoky flavors, which are then carried through to the final whisky.
The level of peatiness in a whisky is measured in parts per million (ppm) of phenols, which are chemical compounds that contribute to the smoky flavor. A heavily peated whisky typically has a ppm of 30 and above, indicating a significant presence of phenols and a strong smoky character.
When you taste a heavily peated whisky, you can expect to experience intense smoky aromas and flavors. The smoke can range from a campfire-like quality to a more medicinal, earthy, or even maritime character. The level of peat can vary depending on the distillery and region, as different regions in Scotland and other whisky-producing countries have their own unique styles of peat.
One of the most well-known heavily peated whiskies is the Islay single malt, which is produced on the island of Islay in Scotland. Islay whiskies are famous for their robust and peaty profiles, often described as having a “peaty punch.” These whiskies can be quite polarizing, as some people love the bold, smoky flavors, while others find them overpowering.
Personally, I have had the opportunity to try a few heavily peated whiskies, and each experience has been quite memorable. I remember one particular bottle from an Islay distillery that had a staggering ppm of 50. As soon as I opened the bottle, the room was filled with a distinct smoky aroma that instantly transported me to a bonfire on a chilly evening.
Upon tasting, the smokiness was immediately apparent, with layers of peat, ash, and even a hint of brine. It was a complex and robust whisky that lingered on the palate long after each sip. While the smokiness was dominant, there were also underlying flavors of citrus, oak, and spice, adding depth and complexity to the overall experience.
Heavily peated whiskies are not for everyone, as the strong smoky character can be an acquired taste. However, for those who appreciate the unique and distinctive flavors that peat can bring, these whiskies can be a true delight. Whether enjoyed on their own or paired with complementary flavors, heavily peated whiskies offer a memorable and immersive sensory experience.
