I don't think he was stupid at all. Last time he was on the show, I'm sure people would have also said he was stupid for not making a deal as well. Now he has a successful brand, and probably knows more about the industry than ever before. Many wine makers are passionate about their products. They are like microbrew beer makers and he likely has a passion for his own product, not just the delivery system. He's sitting pretty on the distribution patent as a fall-back, he got more exposure (and potentially more offers) by just appearing on the show, and he's currently doing well with his business. He is in the driver's seat and doesn't have to be forced into a bad deal if he doesn't want to. Even at 12% for $300k, that's not a great deal. Cuban's deal offer? Even worse. Just needing capital to fill large volume orders that may require a new facility isn't really a "problem" at all. If he doesn't fill that order, he's still probably going to max out capacity at his current facility and still do quite well.
