How many oz of wine are in a glass you order from bar?

Typically, a standard pour of wine at a bar is 5 fluid ounces (fl oz). This is equivalent to approximately 147.9 milliliters (ml). However, the actual amount of wine in a glass can vary depending on the establishment, the type of wine, and the bartender's discretion. Some bars may serve smaller pours, such as 4 fl oz (118.3 ml), while others may offer larger pours, such as 6 fl oz (177.4 ml) or more. It's always a good idea to ask your bartender about the specific measurements they use for a standard pour.
