How many glasses of wine are in a bottle?
According to the CDC definition of a standard glass of wine being 5fl oz and 12% ABV, there are 5 glasses of wine in a bottle. Each 5fl oz glass is 150ml and a full bottle is 750ml so 150ml x 5 = 750ml.
In a bar you may get different sized glasses that cost different amounts and sparkling or dessert wines might have a different size to a glass of red or white wine.

|Drink and volume||Alcohol content|
|12fl oz Beer||5%|
|5fl oz Wine||12%|
|1.5fl oz Spirit||40%|
This means you can quickly tell how many wines you have had compared to a beers of even shots.

Prosecco, Champagne and other sparkling wines may well be served at the smaller size of 4fl oz or 125ml.
A standard serving or the very sweet dessert wine is likely to be 2fl oz

How physically big you are has a huge impact on the amount of alcohol it takes to get you drunk. If you have ever been out drinking with friends, you might notice the larger ones seem they they have hollow legs compared to the smaller ones.
Alcohol is distributed throughout the body so if you have more actual body, less of the alcohol will remain in your bloodstream, lowering your blood alcohol concentration.
Biological females get intoxicated quicker and with lower amounts of alcohol. This is due to a few reasons.
A female will on average be smaller than a male, they have circa 40% less alcohol dehydrogenase (the enzyme that breaks down alcohol) than an equivalent male and they have a higher percentage of fat to lean mass so more of the alcohol is in their bloodstream.
