The identity of their winemaker is supposedly their BIG secret... they claim that they need to keep it a secret in order to keep their price down, or something like that.
This is, I believe, complete marketing BS. The folks responsible for selling this stuff give you this line of bull in hopes of creating a buzz about the wine. If its made by Philippe Melka (for example), he's already collected his money long before the wine hits the marketplace. Why not put the winemaker's name out there to help it sell? The more likely explanation is this, "We have to keep the winemaker's name secret, becasue if we told you who it was, you probably wouldn't be able to get $20 retail for this swill."
I don't know the wine -- it might be great, but this crap about keeping the winemaker secret is just marketing fluff.
