Which whisky is produced at a single distillery and aged in oak casks for at least 3 years?

The question asks for a whisky that is produced at a single distillery and aged in oak casks for at least three years. The correct answer is Single Malt Scotch Whisky, which is made exclusively from malted barley at a single distillery. It must also be aged for a minimum of three years in oak casks, fulfilling both criteria specified in the question.

Single Malt Scotch Whisky is distinguished by its production process, which involves using only water and malted barley. This method results in a unique flavor profile that reflects the character of the distillery’s specific practices and location. Furthermore, the requirement for aging in oak casks enhances the complexity and depth of flavors in the whisky.

While the other options refer to different types of whiskies, they do not meet the criteria as straightforwardly:

• Blended Grain Scotch Whisky involves mixing grain whisky from different distilleries and does not adhere to the single distillery requirement.
• Single Grain Scotch Whisky is made at a single distillery too, but it can include grains other than barley, such as corn or wheat, which separates it from Single Malt.
• Blended Malt Scotch Whisky is a blend of malt whiskies from multiple distilleries, again failing to meet the single distillery criterion.
