I am no wine expert but I do know this much that opened bottles need to be stored and consumed appropriately. Winery is a digital bottle stopper with a sensor that goes into the bottleneck and keeps a tab on the wine. It even relays useful information like temperature, expiry date of the wine via WiFi to your smartphone app. Kinda like keeping a digital eye on your drink!
