There are some guides to fine wines but for me it is the wine I like.
If someone has to give me a lengthily explanation about why a wine is good or fine I've found there is only about a 40% chance that I will like the taste. If they just say "Hey taste this wine." and leave it up to me that chance goes way up.
In short I drink what I like. I don't care about anything else. Back when I used to party with friends who were "Wineys" I always brought a wine I enjoyed. Something they often looed down on as "commercial" like a Blue Nun.
What I always found was that this was the wine that disappeared first.
These days I usually go for something like a white zinfandel.
Red wines or campaign both give me a headache or a hangover, even in small quantities.
I have to say that I'm more of a hard liquor drinker either straight or mixed.
