Ardbeg Uigeadail (pronounced oog-a-dal) is named after Loch Uigeadail, the dark peaty loch in the hills above Ardbeg that has supplied the distillery with its mineral-rich water for over two centuries. The expression is a vatting of Ardbeg spirit matured in ex-bourbon American oak casks and ex-Oloroso sherry casks — the marriage of smoky peat with concentrated dried fruit and chocolate from the sherry wood creates Uigeadail's signature complexity. Bottled at cask strength (54.2% ABV) without chill filtration and without colouring. The expression has won numerous international awards, including Whisky of the Year at the Whisky Advocate.

Ardbeg Distillery was established in 1815 on the south coast of Islay, Scotland's most southerly whisky island, where Atlantic-exposed peat bogs define the landscape and flavour. The distillery is among the most heavily peated in Scotland, with spirit typically reaching around 55 parts per million of phenol. After a difficult period of closure from 1981, Ardbeg was reopened in 1989 and acquired by Glenmorangie Company in 1997, subsequently coming under LVMH ownership. Today the distillery has a fiercely loyal global following through the Ardbeg Committee, a member community of over one million enthusiasts. Islay's damp coastal air and mineral-rich water from Loch Uigeadail contribute to Ardbeg's distinctive medicinal, smoky, and maritime character.
