How many glasses are there in a bottle of wine?
4 to 5.
There are 4 to 5 glasses in a standard 750-mL bottle of wine. The number of glasses depends on the type of wine glass used. A wine glass is best filled half or two-thirds full so that the wine can still be swirled around the glass to release the bouquet. So each glass, depending on the size can have from 187.5 (for larger wine glasses) and 150 mL (for smaller glasses) of wine.
