Why is XO wine so expensive?

XO is the classification of cognac, which is a famous wine producing area in France, and brandy is a kind of spirits made from distilled wine.

Using the most advanced raw materials and aging for a long time is the reason why XO is high-grade. Liquor aged for more than ten years in China is undoubtedly high-grade liquor, but not all liquors have aging potential. Even if you buy an ordinary bottle for ten years, you won't have that quality.

What's more, it also comes with the function of installing B, and there are many people who naturally pay the bill.
