When is it used to make thin wine?

This word is often used in wedding invitations.

The so-called "thin wine" is often a courtesy, just like saying "Yi". It is worth noting that saying "thin wine" is for you, and it is self-modesty. Never say this is "thin wine", otherwise it will make a joke; There is also a saying that thin wine or light drink should be prepared, which is very common in modern wedding invitations. It means that the host family is very modest, saying that the prepared food and wine are not very rich, just snacks or drinks.
