If you look for a way to prepare gyokuro on books or on the internet, you will realize that there is a wide range of brewing conditions among the sources.
Leaf: 2.5-5g (0.088-0.176oz)
Water: 20-40ml (0.7-1.4oz)
Temperature: 40-60C (104-140F)
In gyokuro brewing, you might have experienced that a slight difference in the conditions will make a big difference to the taste. You can think of infinite combinations within the ranges. Have you figured out what’s best for your? I love flavorful gyokuro, so I prepare it with plenty of leaves and a little water in a low temperature. It is something like the following.
Leaf: 4g (0.14oz)
Water: 25ml (0.88oz)
Temp: 45C (113F)
However, I’m interested in other ways since I tried a smooth gyokuro at Gyokuro-no-sato (http://everyonestea.blogspot.jp/2012/05/importance-of-brewing-conditions.html) I’ll do some experiments to find out the way to brew that type of tea that I’ve tried there. I’ll introduce about it on the next entry.
