There's nothing worse than opening a bottle of wine, not finishing it and then it goes bad before you can get another glass. NOT ANYMORE!!!
Thanks to Warner, a Sommelier, this hack will SAVE your wine. The reason your wine goes bad is because it's exposed to too much oxygen for a long period of time, so don't put the cork back into a half empty bottle. Warner says what you want to do is reduce the wine to oxygen ration. She suggests putting the left over wine in a mason jar! This can keep your wine fresh for up to a week!
