This question is a matter of opinion.

Fakes can be sold anywhere, and correspondingly there must be places selling real ones. This really requires the ability to distinguish.

Personally, I rarely buy wine online. I will buy it in offline physical supermarkets. The reason is very simple. Anything sold in offline large supermarkets must be reported to the local relevant departments. If there is a problem, you can always take the shopping receipt to find it.

If you buy online and there is a problem, it may take more time.
