Single Grain Whiskey

Whiskey is one of the most popular alcoholic beverages throughout the world and it can be found in many different flavors and aromas. Single grain whiskey is one that has been manufactured from only one type of malted grain and has been distilled in one certain distillery. Traditionally, single grain whiskey is made from barley cultivated in near proximity to the distillery of production.

Although single grain whiskeys are all created in similar fashion, each one may present a unique taste due to the source of water used in the manufacturing process. Water is a main ingredient in single grain whiskey and the end result is dependent on the type of water used.

Single Grain Whiskey Process

The process, in which single grain whiskey is created, from beginning to end, can take several years. Three main ingredients are used to make single grain whiskey; barley, water, and yeast. Barley is first soaked in water for two to three days, which is known as being malted. This process encourages germination to occur. For a period of three to five days, the mash will germinate and turn to fermented sugar. The concoction is then dried using one of several methods. The single grain whiskey can be dried using hot air from oil, electricity, or coal. Normally, smoke is introduced during this part of the manufacturing process. The final single grain whiskey product will have a slight smoky taste and aroma as a result.

The next step in creating single grain whiskey is the mashing process. Here, the mixture is ground up into a course substance and hot water is added. Mashing helps to extract the excess sugar and is often performed up to three times before it is finally completed.

Single Grain Whiskey Fermenting

In order to create alcohol, the single grain whiskey must be fermented. At this stage, yeast is added which reacts to the sugars; thus creating carbon dioxide and alcohol. This entire stage can take up to three days to complete. Up until this point, the process of making single grain whiskey is very similar to that used to make beer. However, the distillation process is when the creation starts to differ.

Single Grain Whiskey Distillation

During distillation, the concoction is heated to a boil, which evaporates the alcohol. The vapor is then collected, cooled, and condensed back into liquid form. This liquid is what will be known as the single grain whiskey. These steps only take between one and two weeks to complete. It is the maturation process which can actually last up to 20 years. By law, single grain whiskey that has been manufactured in Scotland must be matured for a minimum of three years.

During this time, the single grain whiskey is placed in oak barrels, away from direct heat and sunlight in order to decrease evaporation. Once the single grain whiskey has been placed in bottles, it is important to stand it up to prevent the whiskey from touching the cork. If this happens, the cork could disintegrate, thus affecting the whiskey’s taste.
