Cold-brewed coffee is another option. It brings out different flavors from the coffee than brewing it with hot water - there's much less acidity. While I usually drink french-pressed coffee or tea, I like cold-brewed coffee with chicory (e.g. Cafe du Monde) in the summer.

To make it, I put about 3/4 cup coarse-ground coffee in a 1 qt. jar, fill it with water, and let it steep in the fridge for a day. After that, just strain it - two or three passes through a strainer, then a coffee filter seems to work best. The result is a kind of coffee concentrate - mixing it 50-50 with water seems about right. Refrigerated, it will keep for at least a week or two.

You can make larger batches, of course.
