The secret to making Asyla is the quality of the casks. We use only whiskies aged in first-fill American oak casks because these yield whiskies with more vanilla character, more richness and more sweetness than refill casks. Asyla is made with 50% malt whisky. There are few blended Scotches that use as high a malt content as we do at Compass Box. The result is a carefully crafted, elegant blended Scotch whisky that makes the perfect aperitif.
