How to brew beer in a coffee maker

From Southern Fried Science: How to brew beer in a coffee maker, using only materials commonly found on a modestly sized oceanographic research vessel.

The tools you need are simple: an electric drip coffee maker with hot plate, a coffee filter, 2 1-liter sample jars, 2 handkerchiefs, 2 rubber bands, and a source of clean (preferably R/O) water.

You’ll have to be more creative with your ingredients. What you need are some sort of grain, some malt, and, if possible, something that can act as a clarifying and hopping agent. You need a simple grain to release the tannins, starches, and enzymes. The best bet is common cereals – Raisin Bran, Cracked Wheat, Kashi, whatever you can find. The fruit and nuts will add flavor, but are not important.

Malt is tricky, and sometimes gross. In my experience, the best you can hope for is vegemite, marmite, or some other yeast extract. If you have chocolate malt balls or some other malt based candy, those can be ground up and used as well.
