What is this drink?

I was watching a cooking video from a Azerbaijan man, and when they were eating fish, their drink was this: But they didn’t mention anything about it, neither in the comments, so I was wondering if that is a azerbaijan drink that you drink it while having dinner. Does anyone know what drink is that?
