Use a tea strainer when leaves are placed loose in a tea pot. Strain into cups as soon as possible after the recommended infusion time. Tea leaves left in the cup or tea pot will otherwise continue to increase the tannin content and its undesirable taste.
Tea strainer, made from fine-mesh stainless steel is used for straining tea to separate it from tea leaves. It can also be used to strain liquid from stock or gravy and other similar liquids.
