Caol Ila Distillery is a Scotch whisky distillery near Port Askaig on the isle of Islay, Scotland. Caol Ila (/kɯ:ɫ 'iɫa/ in Gaelic, /kul 'ilə/ foreignized into English) is Gaelic for “Sound of Islay” (lit. "Islay Strait") in reference to the distillery's location overlooking the strait between Islay and Jura.
It was founded in 1846 by Hector Henderson. The distillery did not fare well, and changed hands in 1854 when Norman Buchanan, owner of the Isle of Jura Distillery, took over. In 1863 the business was acquired by Bulloch Lade & Co, of Glasgow, traders in whisky stocks.
By the 1880s over 147,000 gallons of whisky were produced there each year.
