How Many Glasses of Wine Are in a Bottle?

Planning a dinner, a party, or a tasting? The math on how far a bottle goes is simple once you know the one number that matters: the size of the pour.

A standard bottle of wine holds 750 milliliters — about 25 ounces. With a standard 5-ounce pour, that works out to five glasses per bottle. That’s the number to remember. Everything else is just adjusting for pour size and bottle size.

The quick answer: five. The useful answer depends on how big the pour is.

It all depends on the pour

Five glasses assumes a typical 5-ounce restaurant pour. But pours vary a lot. In a tasting room, where servings are smaller (around 2 to 2.5 ounces so you can try several wines), a single bottle stretches to ten or more. Pour a generous 6-ounce glass at home and you’ll get closer to four. So the honest answer to “how many glasses in a bottle?” is: usually five — but count on the pour.

Other bottle sizes

Wine comes in more than one format, and the glass count scales with it:

Glasses per bottle by size (at a 5-oz pour)
Split / Piccolo (187 ml)	About 1 glass
Half bottle (375 ml)	About 2.5 glasses
Standard (750 ml)	About 5 glasses
Magnum (1.5 L)	About 10 glasses
Double Magnum (3 L)	About 20 glasses

Five glasses to a bottle — the one number that makes party planning easy.

A quick rule for hosting

For a dinner or party, a common rule of thumb is about half a bottle per adult across an evening — roughly two to three glasses each — adjusting for the length of the event and your guests. When in doubt, buy a little extra; unopened wine keeps for the next occasion.

The short versionA standard 750 ml bottle holds about five 5-ounce glasses. Smaller tasting-room pours stretch it to ten or more; bigger home pours bring it down to four. For hosting, plan on roughly half a bottle per adult over an evening.
