How many glasses serving per each bottle of white wine?

There's no single answer to how many glasses are in a bottle of wine. It depends on:

* Bottle size: Most common sizes are 750ml, but you can find smaller or larger ones.

* Glass size: Wine glasses vary wildly in size. A standard serving is 5oz, but some are larger.

* Pouring style: Some people pour generously, others like smaller pours.

Here's a general guideline:

* A 750ml bottle typically yields 4-5 standard 5oz pours.

To calculate more accurately:

1. Find the bottle size in milliliters (ml).

2. Determine the glass size in milliliters (ml).

3. Divide the bottle size by the glass size.

Example:

* 750ml bottle / 150ml glass = 5 glasses

Remember, this is just an estimate. You can always pour more or less based on your preference.
