What is signified by the term 'single malt'?

The term 'single malt' specifically refers to whiskey that is produced exclusively from malted barley and crafted at a single distillery. This designation highlights the importance of both the grain and the location of production, ensuring that the whiskey reflects the unique characteristics of the distillery and its methods. By using only malted barley, single malt whiskeys typically showcase a more distinct flavor profile that can vary significantly based on the distillation process, the type of barrels used for aging, and the regional influences of the distillery.

This definition underlines the exclusivity and craftsmanship associated with single malt whiskey, differentiating it from other categories like blended whiskeys or those made from multiple grains. Blended whiskeys, for example, can incorporate different types or brands of whiskey, which dilutes the specific attributes of individual distillation crafts. Furthermore, a 'single malt' does not pertain to the inclusion or exclusion of flavorings; it focuses solely on the ingredients and the production process. Therefore, the choice indicating that single malt whiskey is made from malted barley at a single distillery is the most accurate reflection of this term.
