The cold-water brewing process for coffee, and cold-water brewers sold to employ it, use colder water (room temperature or cold) and longer brewing times to produce less acidic coffee. The process, which actually brews coffee CONCENTRATE rather than immediately drinkable coffee, is also called steeping. A typical cold brewing setup produces enough coffee concentrate to make approximately 20 cups per pound of ground coffee beans, depending on individual taste preference. The concentrate stores well in a refrigerator, and it also stands up to reheating better than coffee prepared by higher-temperature brewing ("hot-brewing") methods. Depending on a coffee drinker's lifestyle, a cold brewer can be more convenient than other methods, since preparation and clean-up may only need to be done once
