Airigh Nam Beist, Gaelic for 'shelter of the beast', is a spring that, together with Loch Uigeadail, provides much of the water used to produce Ardbeg whisky.
The new 16-year-old single malt of the same name is matured entirely in ex-bourbon casks from 1990, and has flavours of crispy smoked bacon and maple syrup, according to the producer.
"By adding another permanent expression to the portfolio we are broadening the range and encouraging trial among key consumers who may want to taste a different profile of whisky," said master distiller Bill Lumsden.
"This expression of Ardbeg is incredibly full of character, yet delicate for a 16-year-old whisky."
The whisky is priced at £44.99 and will be available in Oddbins, Tesco and specialist retailers such as The Whisky Exchange.
