If you haven't heard of cold-brewed coffee yet, check it out here. This method removes ninety percent of the acid from coffee--leaving you with a coffee concentrate, which you can dilute to your taste. There is still caffeine in it, and if you dilute it less, it's like an espresso. The flavor is awesome. Most people buy a cold-brew coffee-maker which costs around $35, but I've figured out an easy way to make it at home without having to buy any equipment. That link above also has an easy make-at-home recipe. Nothing like keeping it simple, eh?

Step 1: Take a large pitcher or jar, put in your coffee grounds, and add filtered water. The recipes I've seen say to add 5 cups of water per pound of coffee. My ground Gevalia coffee comes in an 8 oz. package, which is half a pound. I've found that adding around 1 cup of water per ounce works well. If I have half a package, about 4 oz., I usually put in 4-5 cups of water, until my 2 quart pitcher is full. If I use a whole package, I can pour in about 8 cups of water (using a tall jar). But if you have a pound of coffee, 16 oz., I wouldn't put in 16 cups of water, but about 10 - 12.

Step 2: Let this soak in the refrigerator for about 24 hours.

Step 3: Take a colander, line it with a paper towel, and place it over a large or deep bowl. Pour the soaked coffee grounds with water into this, and let it filter into the bowl. You may have to empty the bowl if it gets too full, half-way through. When it's done, I pour my coffee concentrate into a quart jar which I keep in the fridge.

Voila! One quart jar of coffee concentrate usually lasts me about a week, drinking 1-3 cups a day. You can add as much or as little boiling water to the concentrate as you like. I usually pour in about 1/4 cup of concentrate, and add about 3/4 cup of water. The other day I made Thai Iced Coffee--instead of adding water, I added whole milk and some half and half, along with sweetener--it was delicious.
