Though cold brew has recently become more popular, cold coffee has been around for centuries.
Cold brew is simply the process of steeping ground coffee in cold water for an extended period of time to extract either a ready-to-drink or concentrated cold coffee product. Earliest documentation of this process traces back to the Netherlands and Japan in the 17th century. Likely, for the Dutch, it was a method developed to meet the demands of long voyages, pre-brewing coffee for reheating and consumption later. Cold brew was one of the first products we produced as a company, we still sell it in refillable 2L growlers in concentrate, or ready to drink on tap at our stores. We like to brew it as concentrate because it can be diluted with milk or water depending on how you or your house guests take their coffee. At our stores, we prepare a concentrate and brew about 200 liters at a time. Here is a modified version of our recipe that you can do in your own kitchen! We like it because it requires minimal preparation time for a large quantity of brew that keeps for several weeks in your fridge.
