The Wine Doctor Intelli-Stopper™ is a high-tech “cork” that Preserves the Freshness and Flavor of Wine Stored in Opened Bottles. The Sophisticated Grip-Touch Pump Works with the Intelli-Stopper™ to Remove a Precise Amount of Air From Wine Bottles, Ensuring That Even Days Later Wine Will Be as Fresh and Fragrant as When it Was Opened. We are a father & son owned and operated company devoted to the preservation of fine wines. Like so many good things, Wine Doctor started in the kitchen. On a visit back home to Arizona in the summer of 2005, my father and I reopened a bottle of good wine we had tasted the night before. The stopper hadn't held a seal. Oxygen had leaked in overnight and ruined our wine. We were tired of losing wine because of inferior pumps and stoppers, so that day we decided to create a wine preserver that actually worked. After years of research and testing we have it just right, a vacuum pump that won't fail, and stoppers that don't leak. We know you won't always have wine left to save, but when you do you'll taste the difference with Wine Doctor.
