Caol Ila distillery

Introduction to Caol Ila

A distillery with a view to perfection

Caol Ila is a distinguished Islay distillery, nestled on the northeastern shores of Scotland’s whisky island, overlooking the Sound of Islay towards the Paps of Jura. This iconic distillery produces one of the most elegant peated whiskies in Scotland, balancing smoke with a surprising delicacy that has made it both a cornerstone of many famous blends and a highly-regarded single malt in its own right.

Housed in a striking whitewashed building built into the cliff face, Caol Ila (pronounced “cull-eela”) takes its name from the Gaelic for “Sound of Islay” – reflecting the distillery’s spectacular maritime location.

The History Behind Caol Ila

Origin and development

Caol Ila was established in 1846 by Hector Henderson, becoming one of the earliest licensed distilleries on Islay. Built in a remote bay specifically chosen for its access to fresh water from Loch Nam Ban and its natural port for easy transportation, the distillery embodied practical Scottish ingenuity from its inception.

The distillery changed hands several times through its history, including ownership by Bulloch Lade & Co and later by the Distillers Company Limited. In 1972, the original buildings were demolished and a much larger, modern distillery was constructed on the same site – a testament to the growing demand for its spirit.

Today, Caol Ila operates as part of Diageo’s portfolio, standing as the largest distillery on Islay with an annual production capacity of 6.5 million liters, significantly contributing to famous blends like Johnnie Walker while maintaining its reputation for exceptional single malts.

The people behind

Caol Ila has been shaped by generations of skilled distillers who have maintained its distinctive character while adapting to changing times. The distillery team today continues the tradition of creating whisky that captures the essence of its coastal location, working with a deep understanding of how the maritime environment influences every aspect of production.

From the stillmen managing the distinctive tall stills to the warehouse workers overseeing maturation, each person contributes to maintaining Caol Ila’s reputation for consistency and quality.

The Craft and Production

From raw materials to finished product

Caol Ila’s production begins with malted barley, peated to approximately 35 phenol parts per million – a moderate level that allows both smoke and other flavors to shine. The distillery uses water from Loch Nam Ban, which flows over peat before reaching the production facility, adding subtle character.

One of Caol Ila’s most distinctive features is its six large, lantern-shaped copper stills. These tall stills with their steep lyne arms create significant copper contact, resulting in a lighter, cleaner spirit despite the substantial peat influence. This unique distillation process is key to Caol Ila’s characteristic balance between smoke and delicacy.

Maturation and aging

The new-make spirit is filled primarily into ex-bourbon American oak casks, which bring vanilla, coconut, and sweet notes that complement the peaty character. Some expressions also feature European oak or sherry cask maturation, adding layers of complexity with dried fruit and spice notes.

The maturation warehouses at Caol Ila experience the full influence of the island’s maritime climate, with the sea air permeating the casks and contributing to the whisky’s distinctive coastal character. This environment creates a whisky that evolves beautifully with age, developing remarkable depth while maintaining its essential oily, smoky profile.
