After the barley has been mashed, it is fermented in the distillery's wooden washbacks before being twice distilled through Talisker's copper-pot stills. The stills are equipped with unique swan-shaped lye pipes and worm tubs. As a result of this configuration, a portion of the vapor during distillation condenses before reaching the cooler, and runs back into the still for redistillation. This process gives Talisker Single Malt Whisky its signature, full-bodied flavor profile. Talisker 30 is the oldest single malt in their core lineup. Released annually in limited quantities, the whisky has spent its 3 decades in a combination of ex-bourbon and ex-sherry casks, resulting in a wonderfully mature, complex, and nuanced expression that's bottled at 91.6 proof.

Rich and beautifully balanced, deep and aromatic, and infused with a delicate sweetness, this truly exceptional 40 Year Old single malt whisky is the product of just five refill casks originally laid down before 1979. These casks were brought together in 2008 and filled into first-fill sherry seasoned American oak casks to intensify the maturing whisky's flavour over a further 10 years of maturation. The refill casks that originally held this whisky are ideal for a long, slow maturation while the first-fill sherry seasoned casks in which the whisky completed its maturation, bring a depth of character and nutty, fruit-filled notes of sherry to the fore.
