Have you ever wondered how to store an opened bottle of wine? If yes, then this tip is for you. The basic rule that you need to know is that oxygen, sunlight and high temperatures (above +24 Celsius, 75.2 Fahrenheit) are going to transform your wine into Vinegar very quickly. To minimize amount of oxygen pour wine into a smaller bottle. It could be any bottle of your chose. Then put the bottle into the refrigerator. Preferably, lay the bottle horizontally. Now your wine will stay fresh for 3 to 5 more days.
