This confuses me. I understand the principle, and I agree with Mike (wow!)...just some big wigs trying to protect their monopoly....BUT, if you have a GOOD product....one that is 'differen't than the others, the competition wouldn't matter so much??
Take California...very popular for their wine. Cali wine is different from French wine which is different from Italian wine and so on.....people tend to stick with a type of wine they like....if NY and MI wine makers each produce a unique type of wine, they will each cater to a different audience....not the same audience.
Am I totally off here? (completely possible because I'm not even at novice level where wine is concerned....I mix all my wine with 7up thanks to my Nonna.)
