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,
How many glasses can you get out of a normal bottle of wine?
—Tim, Gastonia, N.C.
I’ll assume that by “normal” bottle you mean a standard 750ml bottle, which is just about 25 ounces. The USDA defines 1 serving of wine as 5 ounces (or about 150ml), which means there are about five glasses’ worth of wine in a 750ml bottle. Of course, wineglasses vary widely in size, and that can make it difficult to accurately pour a 5-ounce serving.
