Fill red wine glasses one-third full, white wine glasses one-half full and sparkling wines, like champagne, about three-quarters full. Filling a red wine glass only one-third full allows you to give it a good swirl.

Also, how is wine pour measured? Perfect Pour Use a measuring cup and fill the cup until the wine reaches the 5-ounce mark. If your measuring cup doesnt have ounces marked and you dont need an exact measurement, pour the wine just shy of 2/3 of a cup. If you do need an exact measurement, pour one 1/2 cup and then add 2 tablespoons.

Secondly, how many ounces should a glass of wine be?

Red wine glasses can range from a minimum of eight ounces to well over 22 ounces. However, the standard red wine pour is five ounces, no matter what the size of the glass is. For comparison, a standard white wine glass holds between 8 to 12 ounces, but a standard pour of white wine would only be 5 ounces in the glass.

Why do you fill wine glasses half full?

The reason why waiters (and wine pouring staff in general) will fill your glass less than half full is to allow plenty of room for the wine to swirl around in the glass and release the aromas of the wine. Smelling the wine makes a big difference in how much flavor youll eventually pick up in the wine.
