Last week I read an article in the NY Times about cold-brew coffee and decided to try it.
How it works. You buy a special plastic brewing container, it holds about a half gallon of water and one pound of coffee. There's a hole at the bottom of the container, which takes a plug, and has a place to lay a filter which is about 1/2 inch thick, made of some kind of fiber. You let the whole thing stand for 3 or 12 hours (depending on whose instructions you're following) and then pull the plug and put the plastic container on top of a carafe designed to fit under it. Let it drip for about 1/2 hour and then put the carafe in the fridge. The next morning it's cold and ready to make into iced coffee, or to be diluted (it creates a concentrated coffee) and zapped in a microwave.
