Add your teabags to a pitcher or place your loose-leaf tea into a metal tea strainer or a linen or cotton reusable tea bag. For this method, a good ratio is around one spoon of leaves for four to six cups of water. Try to avoid using a plastic tea infuser, as this can leech and impact the flavor. Fill the pitcher with cold water.
Place your pitcher in the fridge for between six and 12 hours.
Stir the contents of the pitcher and remove the tea strainers.
Pour your cold brew tea into a glass with ice and serve. Feel free to add sweetener.
Place the pitcher back in the fridge without the tea infusers and enjoy another drink later on.
