Not who you were asking, but it's pretty much steeping coarse coffee grounds and cold water in a cup overnight, then filter out the grounds, sort of like cold sun tea. In New Orleans toss in some chicory. I use the Toddy, which steeps 12oz grounds in 56 fl oz of water, drained through a fuzzy fabric filtering puck; the extract can be refrigerated and diluted with hot water or cold milk. There are smaller CoffeeSocks (cloth filters) if you don't want to have a carafe of extract in your fridge for two weeks.
