Save some money and make your own cold brew at home. This coffee recipe is so easy--plus you can make a double batch to have plenty on hand for an instant pick-me-up. Be sure to use coarsely ground coffee beans for cold brew. Finely ground coffee can make it cloudy. Source: EatingWell.com, May 2018
You can also keep your left over coffee in sealed container in fridge so you always have some on hand & it's already cold so no need to water it down with ice cubes if you prefer it stronger.
