A large selection of best Japanese tea sets at amazing price! A tea ball is a great way to brew green tea, and tea made with it will always taste good. However, in many cases it is simply too small for the tea leaves to infuse properly. This means that you will not achieve the full flavor from the loose leaf. Instead, we would suggest that you use a teapot that has a removal metal basket, and you can place the loose leaf tea here. A teapot called Kyusu has a metal strainer that lies over the inside of the spout, which means that you can put the loose leaf green tea directly into the teapot.
