Be prepared to drink a lot!
The Svans have their own potent firewater called "Chacha" (approx. 60% alcohol) made from fermented apples to fermented bread to fermented herbs.
They toast 3 times. Each time for a divine entity. Can't remember who they are but one of them is definitely St. George, the patron saint of their country. On one of the toast, you're invited (and expected) to give a short speech...
They also drink something called Rakhe which is some herbally hard liquor similar to the Turkish Raki and Greek Ouzo... and you'll be made to drink copious amounts of those too. To decline may be deemed offfensive or impolite. And to appear inebriated is most distateful! So feign a poor stomach or some debilitating sickness which will excuse you from libation.
Svanuri's (and Georgian) not the easiest language to pronounce so i'm going to transliterate it to the best of my ability.
