Auchentoshan has a clean complex character starting with malted optic braley. It is gently kilned and the barley used is completely unpeated. During the milling stag the barley gets grinded to suit the lauter tun, it is vital to have all evenly milled starch grits, this maximises the amount of starch that converts into sugars during mashing.
To the mashing phase, where milled, malted barley and pure water get feed into the lauter tun at 63.5°C. The heat helps turn the starches into sugar, after two filling the mix is ready for fermentation.
Unlike many distilleries that prefer the consistency that comes with stainless steel washbacks, Auchentoshan uses Oregon pin instead so the results are always a little different each time, which also means the mash men need to keep a specially keen eye on the mixture.
Distillation takes the fermented liquid from around 8% ABV to 81%. No other Scottish distillery distils its whisky 3 times, and the max ABV they reach is 70% mean they will have more impurities than Auchentoshan's.
After the liquid has been distilled to the correct ABV it is time for the maturation process. This takes place in oak casks that have been specially selected for their superior aromas. The different casks used have previously held bourbon, sherry or fine wines which all add their own unique flavour to this full bodied, smooth single malt Scotch whisky.
