Islay whisky at Glenbotal

Islay is one of the deepest sections of the shop. Ardbeg leads, followed by Bowmore, Bruichladdich, Laphroaig, Caol Ila, Bunnahabhain, Kilchoman and Lagavulin. There is a deep choice of Port Ellen, Bruichladdich's peated Port Charlotte and Octomore lines, Ardnahoe, and blended malts such as Big Peat and Elements of Islay. The range runs from standard 10 year olds to limited Ardbeg editions, festival bottlings and old vintages.

Peat, sea and the island style

Islay sits off Scotland's west coast and is known above all for peated single malt. Barley is dried over peat smoke, which leaves phenols measured in parts per million (ppm). Laphroaig, Lagavulin and Ardbeg on the south coast make the classic smoky, medicinal style. Not every Islay malt is peated: Bunnahabhain and Bruichladdich both make unpeated spirit, and Bowmore sits in the middle with a softer smoke.

The distilleries

  • Bowmore (1779) is the oldest licensed distillery on the island and still malts part of its own barley.
  • Laphroaig (1815), Ardbeg (1815) and Lagavulin (1816) line the south coast.
  • Caol Ila (1846) is a key malt in Johnnie Walker blends.
  • Bruichladdich and Bunnahabhain date from 1881; Kilchoman opened as a farm distillery in 2005.
  • Port Ellen closed in 1983 and reopened in 2024; earlier bottles hold the original spirit.

What to look for

Islay releases come in many editions with similar names, so check the edition and year: Ardbeg Uigeadail, Corryvreckan and the annual committee releases differ, as do Lagavulin 16 and the Distillers Edition. Octomore labels show the edition number and peating level in ppm.

Frequently Asked Questions

Why is Islay whisky smoky?

Islay whisky is smoky because much of it is made from barley dried over peat fires, and the peat smoke leaves phenolic compounds in the malt. Islay peat is known for giving a medicinal, maritime smoke. The amount of smoke depends on each distillery’s peating level and still shape.

How many distilleries are there on Islay?

Islay has ten working whisky distilleries: Ardbeg, Ardnahoe, Bowmore, Bruichladdich, Bunnahabhain, Caol Ila, Kilchoman, Lagavulin, Laphroaig and Port Ellen, which reopened in 2024. Bruichladdich also produces the peated Port Charlotte and Octomore ranges. More distilleries are being built on the island.

Which Islay whisky is not peated?

Bunnahabhain and Bruichladdich both make mainly unpeated single malt, and their standard bottlings have little or no smoke. Bowmore is lightly to moderately peated. Ardbeg, Laphroaig, Lagavulin, Caol Ila and Kilchoman are the heavily peated ones.

What is Port Ellen whisky?

Port Ellen is an Islay distillery that closed in 1983 and was rebuilt and reopened by Diageo in 2024. Whisky distilled before the closure was released in limited annual editions and by independent bottlers, and it is among the most collected Scotch. New Port Ellen spirit will need many years before it reaches similar ages.

What is Ardbeg Uigeadail?

Ardbeg Uigeadail is a cask strength Islay single malt named after the loch that supplies Ardbeg’s water. It combines bourbon cask and sherry cask whisky and is bottled at 54.2% ABV, giving heavy peat smoke with dark fruit and sweetness. It has no age statement.

What does ppm mean on Octomore and other peated whisky?

PPM means parts per million of phenols in the malted barley, a measure of how heavily it was peated. Most peated Islay malts use barley at around 35-55 ppm, while Bruichladdich’s Octomore has used barley peated well above 100 ppm. The figure refers to the barley, and the finished whisky contains far less.
