01 MALT, MILL AND MASH

Our trademark complex character starts with malted optic barley. Gently kilned, completely unpeated barley lets the Auchentoshan taste shine through from our distillery in Glasgow.

01 MALT, MILL AND MASH

We grind the barley to suit our lauter tun. It’s vital we have evenly milled starch grits, maximising the amount of starch that magically transform into sugars during mashing. All this hard graft means a fresh-tasting, clear wort from the lauter tun.

01 MALT, MILL AND MASH

We feed the milled, malted barley – and pure water – into our lauter tun at 63.5°C. The heat helps turn the starches into sugar. After two fillings we are ready for fermentation – the third filling is used as the first water in the next mash.

02 TRIPLE Distil

Distillation takes our 'Distillers Beer' from around 8% ABV up to 81%. We insist on triple distillation in every drop – since double whisky distillation usually reaches just 70% ABV.

02 TRIPLE Distil

The Auchentoshan story is about a commitment to triple distillation - distilling each and every drop three times for the smoothest spirit. 

 

Because we distil away the impurities in the liquid, strong notes of fruit and citrus come through. 

 

It also makes the spirit more prone to the epic woodiness that comes from the casks in maturation.

03 WAIT

Our oak casks have a huge influence on flavour - so we spend a lot of time selecting them. 

 

The right casks.  
The right setting.  
The right weather.

O3 WAIT

If a spirit wants to be called Single Malt Scotch Whisky, it must be matured in oak for at least three years - no less. We go much further. 

 

Our whisky is matured in casks which held bourbon, sherry or fine wine. This is an essential step in creating Auchentoshan - the spirit and the wood work together over many years, lending colour and flavour to the finished whisky.

O3 WAIT

So it's no surprise we spend so much time and effort selecting precisely the right casks - or indeed in balancing the unique flavours each cask imparts. That way, we create a whisky with flavours right across the spectrum.
