Hello there! I'm Dr. Vinifera, but you can call me Vinny. Ask me your toughest wine questions, from the fine points of etiquette to the science of winemaking. And don't worry, I'm no wine snob—you can also ask me those "dumb questions" you're too embarrased to ask your wine geek friends! I hope you find my answers educational, empowering and even amusing. And don't forget to check out my most asked questions and my full archives for all my Q&A classics.
Dear Dr. Vinny,
This question might sound a bit silly, but I accidentally took a sip from a glass with some sparkling wine in it that was left out overnight (I didn’t drink all of it, and forgot to clean it up in time.) It didn’t taste that great anymore. Is there a chance this could make me sick?

Drinking flat, warm Champagne is probably unpleasant, but it won't make you sick. If you taste wine that's been opened and left out, you'll probably notice that the flavors have faded overnight and the wine has started to oxidize—similar to the way an apple slice will start to turn brown as it is exposed to oxygen, then will start to turn brown and the fruit flavors will start to be replaced by more nutty notes. But wine doesn't spoil the way food does, and you will be fine.
If you have any open leftover bubbly that you want to preserve, keep it in the fridge; a hinged bottle stopper will help keep the carbonation intact for at least another day or two.
