I don't normally drink Francis Ford Coppola's line of wines. They just strike me as generic grocery store wines. But to each his own, especially if they suit one's budget.
But everyone should be aware of what Coppola is doing right now and should send them a message by boycotting the brand. Coppola has launched a law suit against basically any winery that uses the word "diamond" or even incorporates a diamond shape in any way on their labels. Ostensibly it's to protect their "Diamond Series" brand, but in reality it's the equivalent of legal napalm to raze everything in their path.
This sort of litigious corporate terrorism cannot be tacitly condoned. If folks stop buying their wines until they drop the suit, that will get their attention.
