When I typically brew sencha in my tokoname kyusu, by the time I am ready to brew my second infusion, the kyusu has usually cooled down significantly since my first infusion. It isn't necessarily cold, but not hot like when I pre-heat it before the first infusion. I was wondering how I would take this into account when determining the proper water temp for additional infusions. For example, lets say the sencha I am brewing calls for 170F and the "cool" teapot will cause the water temperature to drop 10F when refilled. Should I then add 180F water to teapot for the second infusion, so that it reaches 170F for brewing?
