Glad to see my progress in the world of beer 🙂
I didn't research if the idea was to be a "tribir". But it seems to me that it is actually a combination of the number 3, which in the Cyrillic alphabet looks the same as the letter Z, and in translation Zbir means "Sum". Because in addition to good beer, they also serve great food, which I will try next time.
Oh, I see :)
