it's definitely going right through the middle of Varna or Veliko Tarnovo
I'll bow to your superior geographical knowledge. I'm way up in The North West beer section bit😬😂.

yah, it was a guess but if you look close at the ribbles along the black sea coast it's definitely going through Varna
they also are including istanbul in europe though
the problem is that everything east of croatia and hungary is actually the brandy homeland, palinka, rakija, ракия depending on which part, but it's much the same... spirit distilled from fruit wines (mostly plums) and greece their thing (and the turks) is ouzo (raki) which is basically vodka spiced with aniseed
