The "rule" for infusion baskets (or strainers) is quite simple: to be successful, they should nearly fill the entire space inside your teapot, cup or mug. There are many types available: tea socks (cotton fabric), paper filters (t-sacs), ceramic inserts, cylindrical mesh inserts, mesh balls, pincer spoons, polyester and wire-mesh baskets and the bamboo basket.

All types can be used for a successful infusion; however, we do not recommend the popular tea ball or double-sided spoon because there is insufficient room for the leaves to unfurl. The infuser should allow enough room for the leaves to unfurl and swirl to give the tea its full aroma and flavour. The tea ball or double-sided spoon is not recommended with Rooibos; the tiny needles slip through the holes.
