Cold Brew is a preparation with cold water or at room temperature. This type of preparation is quickly becoming very popular among specialized restaurants and coffee shops around the world. But how does it work? Cold brew consists of infusing ground coffee or loose leaf tea with cold water for several hours; this results in a drink that is served cold, but maintains all its properties. This preparation, even if it takes time to infuse your favorite coffee or tea, may be the best alternative to your anxiety to enjoy them, in times of strong heat.
