What defines a blended whiskey?

A blended whiskey is defined by the fact that it is a mix of different types or brands of whiskey. This can involve combining various grain and malt whiskeys, often from different distilleries, to create a product that has a consistent flavor profile. The blending process allows for the unique characteristics of each whiskey to come together, resulting in a balanced and often smoother spirit.

The other points mentioned clarify why they don't define a blended whiskey. While some whiskeys are aged for a minimum of five years, this aging requirement applies to many types of whiskey, including straight whiskey, and is not exclusive to blended whiskey. Additionally, not all blended whiskeys are made in Scotland; blended whiskeys can be produced in various countries, including the United States, Ireland, and Japan. Finally, a single type of whiskey would not fall under the category of blended whiskey, as blending inherently involves the combination of multiple whiskeys. Thus, the core attribute of blended whiskey lies in its mixture of different types or brands, confirming that choice about blending is the defining characteristic.
