How many glasses are in a bottle of Prosecco?
The short answer
A standard bottle of Prosecco holds 750 mL, about 25.4 U.S. fluid ounces. That is six 125 mL pours or five 150 mL pours. The bottle is consistent. The friend doing the pouring may be less so.

The full answer
A standard 750 mL bottle of Prosecco pours five glasses at 150 mL (about 5 oz), or six at 125 mL. That is about 25.4 U.S. fluid ounces in all. The bottle is consistent. The friend doing the pouring may be less so.
You have six people coming for dinner and one bottle chilling. On paper, this works beautifully. Then someone reaches for the large glasses.
Bottle arithmetic becomes much more useful when you start with the pour. A 750 mL bottle contains a fixed amount of wine; “a glass” is a rather more flexible arrangement.
Standard Prosecco bottle size and number of glasses
For a toast, agree the pour before filling the glasses. Otherwise the first four guests receive a generous welcome and the last two receive an explanation.
| Planned pour | Pours from 750 mL |
|---|---|
| 100 mL | 7 full pours, with 50 mL left |
| 125 mL | 6 |
| 150 mL | 5 |
These are serving calculations, not recommendations about how much anyone should drink. Allow for spills rather than expecting every last millilitre to arrive neatly in a glass.
What is that in fluid ounces?
A standard bottle is 75 cL, or approximately 25.4 U.S. fluid ounces. NIST gives about 29.57353 mL per U.S. fluid ounce; dividing 750 by that figure gives 25.36. Fluid ounces measure volume here, not weight. Imperial fluid ounces are a different unit.
Does a bigger bottle solve the problem?
A magnum holds 1.5 litres, twice the standard bottle. A half bottle holds 375 mL. WSET identifies 750 mL as the common retail format, but read the stated volume when choosing another size. A handsome silhouette is not a measurement.
When planning to serve Bella Principessa, check the volume on the bottle or specific listing, then choose the pour that suits the occasion. The same arithmetic applies whether the invitation says dinner or simply “come over.”
Planning for guests? Use bottles of Prosecco per guest. For what happens after the cork comes out, see keeping Prosecco after opening. Bottle volume and alcohol content are separate pieces of information.
