How many glasses in a bottle of port?

There's no single answer to how many glasses are in a bottle of port because:

* Bottle Size: Port bottles come in various sizes, from the standard 750ml to larger 1.5 liter bottles.

* Glass Size: The size of your glass will drastically affect how many servings you get. A standard wine glass holds about 5 ounces, while a smaller port glass might hold 3-4 ounces.

* Personal Preference: How much port do you like to drink per serving? Some people prefer a small sip, while others enjoy a larger pour.

To estimate, consider:

* A standard 750ml bottle of port: You can likely get 6-8 servings, depending on the size of your glass.

* A larger 1.5 liter bottle: This would give you double the servings of a standard bottle.

It's best to be on the safe side and assume you'll get 6 servings from a standard bottle of port, and then adjust for glass size and your desired serving size.
