What is the required aging period for XO Premium Armagnac?

The aging requirement for XO Premium Armagnac is indeed a minimum of 10 years. However, for your specific query regarding the option that states "20 years," it appears there may be some confusion, as XO (Extra Old) Armagnac must be aged at least 10 years, but many producers choose to age their products significantly longer to enhance complexity and character.

The term "XO" typically denotes a higher quality level where the spirit is aged longer than the minimum. In practice, while it may be common for XO Armagnacs to be aged for well beyond 10 years, including 20 years for premium selections, the legal requirement is only 10 years.

Understanding the aging of spirits like Armagnac plays an important role in appreciating their development and quality. Aging affects flavor, aroma, and overall profile, as the spirit interacts with the wood of the barrel, which is why many brands will promote a longer aging period as a hallmark of quality.
