How many glasses of wine in a bottle?

Calculating the number of glasses that can be served from a bottle is a frequently asked question. Whether it's for a special dinner, a tasting or simply to organise a get-together with friends, knowing this information can help you plan with precision. 

This article explains how many glasses you can get from a bottle of wine and what factors can influence this quantity.

The standard size of a bottle of wine

Most wine bottles have a capacity of 750 ml, a universally accepted format for red, white and rosé wines. However, other sizes can alter the number of glasses served, from the half bottle of 375 ml to the imposing magnum format of 1.5 litres.

The measure of a glass of wine

In the UK, a glass of wine can be served in different sizes:

• 125 ml (standard size in many restaurants and bars),
• 150 ml (common at formal dinners and wine tastings),
• 175 ml (a generous portion for personal enjoyment).

The choice of the quantity served depends on the occasion and the type of wine, as some, such as sparkling wines, are usually served in smaller glasses to preserve the bubbles.

How many glasses of wine are there in a bottle?

Depending on the size of the glass, a 750 ml bottle yields approximately:

• 6 glasses of 125 ml,
• 5 glasses of 150 ml,
• 4 glasses of 175 ml.

These values may vary slightly depending on the type of wine and the serving technique. In tastings, for example, the portions may be smaller to allow for the tasting of several wines without exceeding consumption.
