Osmanthus Wine is, pretty self explanatorily, a type of wine made out of osmanthus, a plant that grows on the form of shrubs or
small trees (mainly on Asia).
Commonly used as a joke between Genshin Impact players, as it is part of a voiceline repetitively
said by the character Zhongli;
“Osmanthus wine tastes the same as I remember, but where are those who share the memory?”
Nobody knows what the memory is, now who are “those who share it”.
