I'm a longtime Chowhound & writer working on a piece about bombardino, which I recently encountered in Bolzano. I'd long known about VOV, but I didn't know about this version.
Problem is, while I've found a few things in English about the drink online, I can find very little about the drink's history or the culture surrounding it. The closest I've come so far is a horrible translation from an old Italian-language ski forum thread.
If I understand it correctly, the drink was probably invented in Livigno in the 70s. But who knows if the info is accurate...
The same goes for VOV itself. Damned if I can find anything close to an official website; the closest approximation is a newsletter from 2003:
Even my contact at the Italian Trade Board is having trouble figuring out who distributes it, etc. (I know it can also be made from advocaat.)
Anyway, do any of you out there know about bombardino and its history?
