                                The amount of caffeine in an infuser is not a fixed number, but varies widely based on several key factors. In fact, caffeine levels in brewed tea can range from 0mg in herbal varieties to over 80mg per cup for certain strong black teas. The infuser itself is just the vessel, but the type of tea, brewing temperature, and steeping time all play crucial roles in determining the final caffeine content of your infusion.
