Cold brewing is a whole different thing that produces much better coffee

I'd never heard of cold brew until this thread. I made some yesterday. I was surprised at how much the beans soak up, you're definitely right about the amount it makes. I used 4 cups water, thought I'd get 4 cups back, not even close.

The internet is all over the place on recipe ratios, mostly because people confuse weight and volume. Near as I can tell, a good ratio is about 1 coffee to 4 water by volume, or 1 coffee to 8 water by weight. (Or mass. Please let's not go there.)

My family buys a lot of expensive iced coffee, maybe this will save some money.
