Have you ever noticed that the taste of green tea can be changed by brewing temperature? Water temperature is always a key to prepare delicious Japanese green tea. When green tea is brewed with low temperature, we find it more sweet and less bitter. The reason is that more theanine can be extracted into cooler water. Theanine is a component makes sweetness and umami (rich savoury taste). On the other hand, caffeine which brings bitterness and astringency, is less extracted in cold tea.
Taking advantage of those characteristics, Japanese green tea can be brewed with cold water. It is popular to prepare tea in hotter days in Japan. All you need is one heaped tablespoon of green tea leaves, one litre of water and a one-litre glass bottle.
- Place tea leaves in a glass bottle; pour water.
- Keep it in a refrigerator for a few hours.
- Stir once and wait tea leaves to settle down at the bottom; pour into a glass.
Green tea made with cool water is recommended to consume in one day as it has no preservatives. This crystal green colour tea will be very refreshing and a good alternative to soft drinks.
