If the package is unopened and produced by a regular manufacturer, there are two reasons why there is no wine in the bottle:

First, the bottle cap leaks, and the wine box will be lost when it is inverted after production.

Second, the quality of the bottle, some small pores, can not be seen clearly without naked eye observation. In actual production, there is such a phenomenon that the wine is gone, I don't know where it is, and I won't know until after testing.

It can also remove the irresponsible empty bottle phenomenon in production. In this case, there will be traces of leaking wine in the box.

After drinking the empty bottle, analyze what the claim is, and claim from the dealer, which will generally be handled.
