How much coffee for 30 cups?

That really depends on how strong you like your coffee. I think most containers call for one tablespoon of coffee per cup. I don't particularly like mine that strong, so I use about 10 tablespoons for a 12-cup pot. If you were making a 30-cup pot of coffee, I would use anywhere from 24-30 tablespoons of coffee (about 1 1/2 cups) depending on your preference.

For strong coffee, you can use the ratio of 1 spoon of ground coffee to every cup. But for a big 30-cup pot, you can reduce the measurement to 25 spoons of ground coffee.

You will need 30 cups of cold fresh water. 15 tablespoons of fresh ground coffee. Make sure the pot is spotlessly clean.
