How Many Glasses of Wine are in a Bottle

4-6 Glasses on Average.

The standard 750 ml bottle translates into 25.4 ounces, just over 1.5 pints or over three-quarters of a quart. So how many glasses is that?

Wine bottle sizes weren't always uniform. Though mass adoption of glass bottles began in the 17th century, the Romans were the first to use them. According to tradition, the average bottle size was about the extent a glass blower could blow then and now. Some larger bottles were used for storing wine, some for medicine. In the Middle Ages, there was a general tendency to make smaller bottles. By the 18th century, glass became more common, and so did even smaller bottles.

A "standard" glass of wine is 5 ounces which translates to 147 millimeters. On average, a bottle of wine usually yields 4-6 glasses, as this number is highly amenable to the size of glass and type of bottle. It all depends on the varietal, alcohol level, and occasion. For example, you could serve ten drinks of port (high alcohol content and very sweet) out of one bottle.
