Auchentoshan, uncommon for being a lowland whisky, is also unique for using triple distillation. (Springbank’s Hazelburn line uses the same technique, but no other Scottish distilleries triple-distill routinely.) Triple distillation used to be more common, since with a mix of grains, you should get a smoother whisky with a third distillation. Over time, the rationale has become moot, as single-malt Scotch has been codified to use only barley malt for the grain, so the expensive extra step for a third distillation isn’t seen as necessary. Auchentoshan continues with the practice to produce a light whisky with fewer heavier oils and proteins from the mash. Since the mash uses only unpeated barley, we’re anticipating a delicate flavor.
