Scotch whiskies are traditionally divided into Highland and Lowland whiskies. The place of origin of Auchentoshan 18 Years north of Glasglow is geographically seen as one of the Central Lowlands and is situated at the transition from lowland to mountainous areas. Like many other Scottish whisky distilleries the Auchentoshan Distillery has gone through numerous changes of ownership. It was founded in 1823, although some experts assume that it emerged from the Duntocher Distillery, which was founded in 1800. The truly special feature of the production process is the triple distillation that all single malt Scotch whiskies of this brand undergo. De facto the spirits are the only Scottish single malts that are distilled three times. During this process the alcohol content of the liquid increases from 8% to 81%. This allows the fruit and citrus notes and later the wood aroma from the oak barrels to come out better. The Auchentoshan 18 Years has been aged for 18 years in American bourbon barrels before being bottled in 70cl bottles at a drinking strength of 43%. Its taste has nuances of citrus fruits, green tea and roasted almonds.
