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.
