If you already have the coffee beans, you will need to buy a coffee grinder, electric is the best. If you have not purchased the beans, you can grind them in a special grinder at most food markets. Then, you will need a drip coffeemaker. For 10 cups, fill the coffeemaker with cold water to the line, put an appropriate paper filter into the coffee filter, add 1 T. ground coffee per cup then brew. That’s it!
