title_body: How hot should water be to brew ground coffee directly in a cup?
upvoted_answer: Your method most closely resembles Turkish Coffee, which is suggested to be served at hot, but not boiling temperatures. Since the exposure to the grounds is so direct, it's easy to burn the coffee at boiling temperatures. You want a full body, but not a burnt taste (yuck!) Turkish Coffee World recommends about 158 degrees Fahrenheit or 70 degrees Celsius.
