Here's an excerpt from Ten Ren's website.
The tea leaves are a bright spring green color and the tea has a pale green color, fresh taste with roasted undertones, and a clean aftertaste.
A steeping time of 1 to 2 minutes with about 70°C/160°F water is recommended, with an additional 15 seconds for each successive infusion. Use about 1 tablespoon (3 grams) of tea leaves for about every 5 ounces (150 ml) of water. This tea may be infused 3 or more times. The use of a covered glass or ceramic cup is recommended for steeping in order to fully appreciate the tea leaves.
