A typical bottle of wine contains about 750 milliliters of liquid. When serving wine, a standard pour is generally considered to be around 5 ounces (approximately 150 milliliters). To determine how many glasses this would yield, you can divide the total volume of the bottle by the volume per glass.

Calculating this, you take 750 milliliters and divide it by 150 milliliters per glass, which gives you approximately 5 glasses. However, when considering the extra space in each glass for aeration and not filling them to the absolute brim, it’s reasonable to expect that fewer than 5 full glasses are typically served. Thus, this supports the notion that, realistically, one might pour around 4.5 glasses from a standard bottle when serving in a typical manner.

This calculation and practical serving size make it clear why the answer of 4.5 glasses aligns with standard expectations in wine service contexts.
