How many glasses of wine are in a bottle?

A standard bottle (75 cl) yields about 5 glasses with 15 cl glasses or 6 glasses with 12.5 cl glasses. A restaurant serving is typically 12–16 cl.

How many bottles of wine for a dinner?

Rule of thumb: about half a bottle per guest at dinner, so 3 bottles for 6 people. For longer events, buy more.

Estimate about 0.5–1 bottle per adult guest for the whole evening. The calculator helps with a more precise estimate based on the duration and consumption.

How the calculator works and what it’s for▾

How the number of bottles is calculated

The calculator finds the glasses needed by multiplying guests by glasses per person, then converts glasses to bottles by glass size. A standard wine bottle is 75 cl.

One bottle gives about five restaurant glasses (15 cl) or six smaller ones. For example, 12 guests with two 15 cl glasses each need around 24 glasses, about five bottles.

What you enter and what you get

Enter the number of guests, glasses per person, glass size in centiliters and the price per bottle. You get the total glasses, glasses per bottle, the bottles needed and the total cost.

The cost estimate helps with budgeting once you know the price paid per bottle.

Who it is for

It suits planning dinners, weddings, birthdays and parties when you want to stock just the right amount of wine.

You can adjust the number of glasses and the glass size depending on whether it is a relaxed evening or a longer celebration.

Tips for stocking wine

Keep a little extra on hand for parties, since consumption varies with the guests and the mood. Unopened bottles keep for next time.

Offer water and non-alcoholic options too, so everyone has something they enjoy drinking.
