There’s nothing better than having a glass of wine when you are dining at one of your favorite restaurants on a special night out. The problem with ordering just one glass of wine is that you’re never too sure when that bottle was opened, and how long it was exposed to oxygen, its arch-nemesis. When not properly preserved, oxidation will flatten an opened bottle of wine, making it lose its aromas and flavor rapidly. Luckily for wine lovers, Davio’s Northern Italian Steakhouse in Atlanta has invested in the new wine preservation system, the Coravin.
