anyone drink green tea? can i brew gyokuro at 80c? i read internet all said recommended at 50c, anyone can advise?
Preparation
Merchants selling Japanese green tea typically recommend a unique method for brewing gyokuro which differs from typical tea brewing:
use twice the weight in dry tea leaves for a given quantity of water (e.g. 6 to 10 grams for 180 ml, or 2 to 3 heaping teaspoons for 2 small cups);
use a lower brewing temperature (in the range of 50°C–60°C (122°F–140°F) instead of 65°C–75°C (149°F–167°F) for sencha; for high-end Gyokuro such as National tea jury rank, a temperature of 40°C (104°F) is recommended.);
a longer steeping duration, at least for the first infusion (90 seconds instead of 1 minute for sencha).
Since gyokuro is typically steeped at such a low temperature, sources may recommend preheating both the pot and cup to maintain the warmth of the tea as one drinks it.

http://en.wikipedia.org/wiki/GyokuroEven for normal Japanese green tea 80C is not recommended, as the tea will turn yellow upon 1-2 brews, taste horrible.
80C only suitable for partly fremented tea like Wu Long, tie kuan ying, shui xian.
Hope this help.
