Wanting only a glass or two of wine puts drinkers in a tough spot. Once the bottle’s opened, the wine starts to oxidize and lose its flavor. No rubber stopper will halt the process, leaving partial bottles to go to waste. Greg Lambrecht, a medical-device entrepreneur, figured out a way to solve the problem. The devices that Lambrecht once built used a special needle to access implants without creating permanent punctures. His Coravin Wine Access System uses the same idea to draw wine from a bottle without uncorking it.
