How many glasses of wine in a bottle depends a bit on who you ask...but if you're talking to a pro in the restaurant industry, they'll give you the breakdown of standard pours and servings per bottle for a pinot noir versus a port. Knowing how many ounces in a glass of wine and how many glasses are in a bottle can help you plan how far your wine will stretch, no matter how many people you're serving.
How Many Glasses of Wine in a Bottle?
Figuring out how many glasses in a standard size bottle of wine all depends on how large or small you make your pours. A standard glass of wine is 5 ounces. This is typical for any dry white, red, orange, or rosé wine. A standard bottle is 750mL, or about 25 ounces of wine. So, a normal 750mL bottle has 5 standard glasses of wine.
How Many Ounces in a Glass of Dessert Wine?
Things shift a bit when you start pouring things like port, dessert wine, or some bottles of bubbles. In the case of port or dessert wine, the higher alcohol often dictates a smaller pour--typically 2 to 3 ounces--so you may squeak 10 glasses out of a bottle.
Wine Servings in Non-Standard Sized Bottles
The larger the bottle, the better a wine ages, so occasionally you'll find magnums. Magnums are 1.5L and are the equivalent to two standard bottles of wine. In the case of sparkling wines for a Champagne toast, there are plenty of standard 750mL bottles that make for 5 glasses, but there is also a whole array of sizes from petite to absolute jumbo. If you find yourself lucky enough to have a big one in your position, you can just divide the number of ounces by five to figure out how many glasses you can expect to get.
From Bottle to Glass
Pouring wine just right to make sure you get an even five glasses from a bottle may take a bit of practice, but hey, if your friends aren't snooty, no one is going to care if they got a little less than the next guy. So grab a bottle and start making the rounds.
