Quick Guide on How Whiskey is Made at a Distillery.  

Although there are many different ways to make whiskey, all whiskeys start with a few basic ingredients: grain, water, and yeast. Grain is the heart of whiskey making, and the type of grain used will determine the style of whiskey being made.  

The most common grains used in whiskey making are barley, rye, wheat, and corn. Once the grain has been selected, it is milled into a coarse powder called grist. Popular types of whiskey include, but are not limited to:  

  • Scotch whisky which is made mostly from malted barley 
  • Bourbon whiskey which is made mostly from corn 
  • Irish whiskey which is made from a blend of both malted and unmalted barley 
  • Rye whiskey which is made mostly from rye grain 

Water is another critical ingredient in whiskey making. The water used must be clean and free of impurities that can alter the flavor of the finished product. For this reason, most distilleries source their water from nearby springs or underground aquifers. 

Yeast is responsible for fermentation, which is the first step in whiskey production. During fermentation, yeast consumes the sugars in the grist and produces alcohol and carbon dioxide. The type of yeast used can have a significant impact on the flavor of the finished whiskey. 

After fermentation is complete, the liquid (now called wash) is distilled to increase its alcohol content. During distillation, the wash is heated until the alcohol vaporizes and then condensed back into a liquid form. This process is repeated multiple times to produce a high-proof spirit known as low wine. 

The low wine is then transferred to another still for a second distillation. This time, the spirit is distilled at a lower temperature to remove any impurities that may be present. The final product of this second distillation is called high wine. 

The high wine is then transferred to yet another still for a final distillation. This process, known as rectification, produces the finished whiskey. The alcohol content of the whiskey at this point is usually between 40% and 50%. 

After rectification, the whiskey is ready to be aged. Depending on the style of whiskey being made, it may be aged in oak barrels for anywhere from a few months to several years. During this time, the whiskey develops its distinct flavor and color. Once the aging process is complete, the whiskey is bottled and ready to be enjoyed!
