How many 20 oz glasses of beer do you get out a keg?

You can't determine the exact number of 20 oz glasses of beer you'll get from a keg without knowing the size of the keg.

Here's why:

* Keg Sizes: Kegs come in various sizes, the most common being:

* Quarter Barrel (7.75 gallons): Roughly 155 12-ounce pours or 97 20-ounce pours.

* Half Barrel (15.5 gallons): Roughly 310 12-ounce pours or 194 20-ounce pours.

* Full Barrel (31 gallons): Roughly 620 12-ounce pours or 388 20-ounce pours.

* Pour Size: The amount of beer poured into each glass also affects the total number you get.

To calculate the number of 20 oz glasses:

1. Find the keg size (in gallons).

2. Convert gallons to ounces: 1 gallon = 128 ounces.

3. Divide the total ounces by the desired pour size (20 oz):

Example:

* A half barrel keg (15.5 gallons) has 15.5 gallons * 128 ounces/gallon = 1984 ounces.

* Dividing by 20 ounces per pour gives you 1984 ounces / 20 ounces/pour = 99.2 pours.

Note: This is just an estimate. You might get a few more or fewer pours depending on the pouring technique and whether any beer is left in the keg.
