Green tea is sensitive to water that is too hot. Boiling water releases too many bitter compounds – the result tastes harsh instead of fresh.
Let the water cool for two to three minutes after boiling until it reaches about 70–80 °C. Around 4 g of tea is enough for a pot, poured off after about 60 seconds.
Empty the pot completely so the leaves do not keep steeping. That way you can infuse the same sencha up to three times – the second infusion can be a little hotter and shorter.
