The Making of Single Malt Whiskey


The key ingredients in single malt whiskey are malted barley, water, and yeast. Malted barley provides the necessary sugars for fermentation, while yeast converts these sugars into alcohol. The quality of the ingredients used greatly impacts the final flavor of the whiskey.

Malting Process

The malting process is a crucial step in the production of single malt whiskey. During malting, barley is soaked in water, allowed to germinate, and then dried in kilns. This process activates enzymes in the barley that convert starches into fermentable sugars.


After malting, the barley is ground into a coarse flour known as grist. The grist is mixed with hot water in a mash tun, where the enzymes from the malted barley break down the starches into sugars. This sugar-rich liquid, known as wort, is separated from the solid material.


The wort is then transfer to fermentation vessels, typically large wooden or stainless-steel containers called washbacks. Yeast is add to the wort, starting the fermentation process. The yeast consumes the sugars in the wort and produces alcohol and various flavor compounds. This fermentation process usually takes around two to four days.


After fermentation, the wash (the liquid resulting from fermentation) is distill in copper pot stills. The distillation process involves heating the wash in the still, where the alcohol vaporizes and rises through the still neck. The vapor is then condensed and collected, resulting in a liquid with a higher alcohol content known as new make spirit.


The new make spirit is then transfer into oak casks for maturation. The whiskey must legally mature in Scotland for a minimum of three years to be consider a single malt. During maturation, the whiskey absorbs flavors from the wood and undergoes chemical changes that contribute to its complexity and character.
