31. Greg Lambrecht — Founder of Coravin

Greg Lambrecht may be an inventor of medical devices, but he also loves wine — so he used this background and his knowledge of physics, mechanical engineering, and nuclear power to create a device which allows bottles to be accessed and resealed without ever taking the cork out.

Coravin, which he founded in 2013, pushes a non-coring needle through the cork while it's still in the bottle without allowing oxygen to get in. When wine is poured, it's replaced with argon gas — meaning a bottle can still taste good up to 18 months later, which is a game-changer for bars and restaurants looking to expand their wine lists without throwing out half-empty bottles.

The latest edition, the Coravin Model Eleven, also includes an LED display which monitors battery life, pour size, and tells you when the system needs cleaning, Bluetooth connectivity to the Coravin app, which helps users discover new wines or track those they already own in a "virtual cellar," and an automatic pouring function, which allows users to pour the perfect amount with one motion.
