Generally speaking, one tablespoon of grounds makes one decent cup. But different varieties call for different amounts. And some experimentation is needed to account for individual tastes.

If you have a coffee maker that has a heat plate under the carafe, never leave it on that heat for more than a 10 minutes. That ruins perfectly good coffee.

If you’re looking for strong coffee, buy cheep.

You could also try shutting the valve that leads from the brew chamber to the pot and let the grinds steep for longer — that would make a stronger coffee and save on grinds. Or, get a french press, grind the coffee REALLY fine and let the coffee steep for about 10 minutes. This is the best way because it will still taste like good coffee.
