And here's another really interesting report about the Latvian wine market. It's old, but a lot of it still holds true.
For example, I personally don't buy Moldovan and Bulgarian wines, because it's sketchy: they're cheap and sweet.
I don't buy Georgian ones because who knows where they actually come from: Georgia is tiny, yet we have just as many of their wines on the shelves as French ones, banking on the nostalgia of those born in the USSR.
