This size of teapot makes enough in one infusion for a standard tea bowl, and you would need something larger if brewing to fill a mug. That said, this is what this item is for, and making multiple infusions with this teapot is simple. The fine mesh is effective for all but the finest of leaf particles, and the chamber is large enough for the leaves to unfurl properly. This is a Taiwanese product designed in the land of Oolong for drinking it easily, and it especially makes drinking fine tea at work easy and tidy. With some mountain spring water and good tea, even a heavy day at work can better be tolerated.
