Multiple Infusions
Fill the gaiwan to just below the rim, infuse for 5-10 seconds and strain completely into your cup or a jug*. There's no need to reheat the water as you go, because the softened leaves will require lower temperatures to release their flavours - but you will need to extend the time to 10-20 seconds for later steeps.
*Straining with a gaiwan takes a little practice - offset the lid slightly on the pot, hold it in place with your thumb and index finger, and pour out the liquor. Bits of leaf may end up in your cup, but they are harmless. You might want to practise this with cold water and no leaf, just to get to grips with your gaiwan without burning your fingers. Some gaiwans like our Easy Pour Gaiwan Set have a spout to make it easier.
