A brief guide to Islay
The basics
Islay whisky refers to Scotch whisky that is produced on the island of Islay, known for its distinctive smoky, peaty flavor profile. Islay’s coastal location, abundant peat, and unique water sources all contribute to the bold and often briny character of its whiskies, making them some of the most recognizable and sought-after in the world.
Islay whisky is typically smoky due to the use of peat, a dense, earthy fuel source made from decomposed plant matter, which is burned during the barley malting process. The peat smoke infuses the barley with a rich, smoky flavor that becomes pronounced in the final whisky. Islay’s abundance of peat and tradition of using it in whisky production is what gives many of its whiskies their iconic smoky character.
Islay whisky is unique for its intense peat smoke and maritime flavors, often with hints of seaweed, salt, and iodine. While other Scotch whisky regions like Speyside or the Highlands produce lighter, fruitier whiskies, Islay’s whiskies are usually bolder, with strong smoky notes. However, there are exceptions, as some Islay distilleries produce unpeated or lightly peated whiskies.
Islay whiskies are often described as having flavours of smoke, peat, salt, and medicinal or maritime notes. Some whiskies also showcase underlying hints of citrus, vanilla, dried fruit, and spice, depending on the distillery’s production methods and cask types used for maturation.
There are currently nine active distilleries on Islay, including well-known names such as Ardbeg, Laphroaig, Lagavulin, and Bruichladdich, with more new distilleries being planned or under construction. Islay is one of the most densely populated whisky regions in Scotland, and its distilleries each contribute a unique interpretation of the island’s iconic whisky style.
The distilleries
Founded in 1815 on Islay’s southern coast, Ardbeg has a rich history rooted in traditional whisky-making. Known for its heavily peated style, Ardbeg’s whiskies are among the smokiest in Scotland, yet they balance this intensity with surprising complexity and sweetness. Using soft water from Loch Uigeadail and a careful distillation process, Ardbeg produces a spirit that often showcases bold peat smoke, citrus, and a hint of brine, embodying the rugged character of Islay’s coastal environment.
One of Islay’s newest distilleries, Ardnahoe was established in 2018 on the island’s northeastern coast, near Port Askaig. With a commitment to traditional whisky-making, Ardnahoe uses long fermentation and slow distillation to develop a spirit rich in flavor. Sourcing pure water from Loch Ardnahoe and employing peated malt, the distillery produces a whisky that is smoky yet smooth, with notes of fruit, peat, and a hint of salinity, capturing the essence of Islay’s coastal terroir.
Bowmore, established in 1779 in the town of the same name, is one of Scotland’s oldest distilleries.

Founded in 1881 on the northeastern shore of Islay, Bunnahabhain stands apart from many other Islay distilleries due to its focus on unpeated whisky.
