The 50-Cup Coffee Maker
Question. How many teaspoons of coffee per cup of water do I use for the big (50 cup) coffee makers?Answer. The ratio of coffee to water that you use shouldn't differ based on the size of the coffee maker. Having said that, the big fifty-cup "urns" get mixed reviews as they often run into problems after a year of using them, sometimes with little support from the bigger manufacturer of these. If you were making 50 cups of coffee, consider grinding up 2.5 - 3 pounds of coffee for the job.
