Start drinking wine and hanging out with people who will suggest what wine to get, then come back here and tell us about all the BS
There was one blind test where "connoisseurs" picked Chilean over French, then Napa Valley and Australian in another. I know people who scoff at our drinking sweet raspberry+grape wine brought in in large vats with oak planks in them (or our coconut liqueur which without fruit flavors is technically our Moonshine), and only drink the mishandled French wine (tropical country, slow customs at port, unrefrigerated trucks) that are halfway to becoming red wine vinegar.
It's atrocious that these people buy them for $200+ per bottle when you can just blow the same cash on cognac, which travels better.
