My understanding is that in Piedmont, they drink this year’s Moscato and Brachetto at Christmas. Sounds like a good choice. I think Brachetto d’Aqui is one of the better choices for a traditional Turkey dinner.
I think there are two general opinions about the meaning.
The first is what would be considered a “Fine wine” in the wine trade. If Christies were holding a fine wine auction, what wines would you see listed? They would be the ones that fir Gerhard’s definition.
The second is our personal opinion. As in “I think this is a fine wine”.
The difference is the reputation of the producer and/or region. Why is that important? Probably because without any historical track-record, it is very difficult to say whether a particular wine has ageability - and by this I mean the ability to reach greater beauty after several years, not just the ability to last. The other reason is concensus of opinion.
The tongue-in-cheek answer is that it is a great wine that someone who reads a lot of wine books and mags has heard of.
