Donkeykong, look it up, it was I think a few years ago, it was a blind test.
Oh i believe you absolutely.
But you see, you have to understand the mechanics on this.
First, i doubt "Trader Joe's" has his own vineyard. So he probably buys someone's leftovers and sells them cheap. Even the big vineyard sell leftovers under a different label in some years, because they still make a profit with the wine that is still good, but not good enough for the "real" label.
Second, who was tasting the wine
Third, who was financing this event
So you see, it is not so simple.
