[Coda]

Cold brew is coffee made by substituting time for heat. (Sort of like the coffee equivalent of sun tea, in that sense.) It's less acidic because the cold water doesn't leach out as much of the harsher volatiles, and by contrast that also makes the flavor a little bit sweeter. It's a serious pain in the butt to actually make because it takes special equipment (you can buy a kit but it's kinda expensive and the yield is slow) but it's the best iced coffee you could ask for.
