(Wines&Vines) - If you watched ABC’s “Shark Tank” season 3, episode 4, you might reasonably have concluded that Eric Corti sold his wine-preserving device to investors Lori Greiner and Mark Cuban for $400,000. But in the reality TV world, that’s not how it works, and that’s not what happened. The show first aired in February, and was rebroadcast in June. It portrayed tense negotiations between the star investors and the hopeful inventor. Corti was looking for seed money to build inventory and sales of what was then called “The Wine Balloon.”
