Did you know our tea bags also make delicious iced teas and cold brews? Cold-brewing is an easy way to make never-bitter iced tea with bright flavors. To cold brew your favorite Numi tea, simply steep 4 tea bags in 3 cups cold water for 8-10 hours in the fridge. Give the tea bags a good squeeze for flavor before removing. Try infusing your cold brew overnight with fresh herbs or fruit, or mix two different teas to create your own flavor.
