Here's Exactly How Many Glasses of Wine Are In a Bottle

You'll never have to guess how much wine to stock up on again when you're planning your next dinner party.

Life is full of tough questions—like what really is bitcoin? When's the right time to get a flu shot? And, most importantly, how many bottles of wine do I need to get for my dinner party, and how many glasses of wine are in a bottle?

With this guide, you'll learn exactly how many glasses are in a wine bottle, the right amount of wine for 30 (or 40, or 50) guests, plus all the various—and intriguingly-named—bottle sizes out there.

So, how many glasses of wine are in one bottle?

Contrary to what a long day at work might make you want to believe, a typical bottle of wine is not a single serving. Rather, a standard bottle of wine clocks in at 750 mL, or roughly 25 ounces. And no, a "glass of wine" does not mean pouring until it splashes over the top—all that extra air in the glass lets the aromas percolate. General guidelines put one serving of wine at five ounces, so breaking out those math skills tells us that a single bottle of wine is five glasses.

Using this base, you can easily scale up to account for how many guests you're expecting at your next party, whether it's 30 or 300.

Unlike a Snuggie or your grandpa's old sweater, however, a wine bottle is not one-size-fits-all. Bottles sizes range from a capacity of one glass to that of 200 glasses, in an array that's like Russian nesting dolls of boozy pleasure. The next step up from your normal option is a magnum, which is two standard bottles, or approximately one regulation-sized breakup. After that comes the jeroboam (four bottles, or 20 glasses), rehoboam (six bottles, or 30 glasses), and methuselah (eight bottles, or 40 glasses).

If those names sound to you like rulers from hundreds of centuries ago, that's because they are. No one's quite sure why, but we have biblical kings to thank for names like these—as well as the increasingly large Salmanazar, Balthazar, Nebuchadnezzar, and Solomon. The largest one is the Midas, which holds a whopping 40 bottles (200 glasses) worth of wine, and is more of a showpiece than a feasible way to kick back in front of the TV with some vino.

On the other end of the spectrum are bottles that are, in fact, made for a party of one. These are often called piccolos or splits, are typically used to house sparkling wine, and often seen on airplanes. So the next time you're flying economy, ask the flight attendant for a split of champagne and create your own first-class experience with ease.
