I like to call them tea infusers because that term describes what they do. Often confused with a strainer, a tea infuser is a ball or basket that you put your tea leaves in while they brew. The point is easy removal of the leaves once you’re done brewing your tea. You don’t want your brewed tea leaves in the water too long because they will continue to brew and may turn your tea bitter. You can use an infuser in a teapot or in a cup or mug. Simply put the leaves inside, place it in your pot or cup, pour hot water over, and let brew. When ready, lift out the infuser with the leaves and you’re left with clear tea. In general, the larger the infuser and the smaller the holes, the better your results. Tip: Make sure your infuser will fit into your pot. Measure the opening of your teapot and compare to the diameter of the infuser. Different types of infusers include tea balls, brew baskets, and paper or cotton filters. Visit our Tea Infusers and Strainers category to see photos or to buy these items.
