STEEP & GO is your tool for awesome cold brew tea. Simply place a teaspoon or two of tea leaves INSIDE the bottle, fill with cold water, then screw on the filter. Place in refrigerator or on ice to steep. For a faster cold brew store the bottle with water in the refrigerator until you're ready to add tea leaves.
Taste test after about 20 minutes. Different teas will prefer different cold brew steep times. Adjust to your preference—there is no "wrong" way.
