There are various recipes on the internet so I have tired several of the last couple of weeks before coming to one I prefer. As for brewing I have just been using a Kilner jar. Poor in the coffee grounds and iced water, then leave for sixteen hours, decant into a Chemex then in to jar to keep in the fridge for up to two weeks. Easy. Server over ice with milk or even better with cream, and if your feeling really decadent with Tennessee whiskey.
