I purchased the one-pot-size.
The dry needle shaped tea leaves were dark green and turned mushy with a small leaf size after steeping.
The fragrance of the dry tea leaves were sweetish vegetal. My Steeping Instructions were 10g per 90ml water, at 60-80°C for 10sec-2,5min. 4 Infusions were possible.
The liquor was slightly turbid and yellowish green with an umami-rich taste which was slightly salty and sweet, smooth and slightly viscous.
Conclusion: An umami-rich tea, which changes its flavor profile slowly.
After brewing this Gyokuro you can enjoy its used tea leaves by adding a little soy sauce and citrus juice.
My tea leaves were mild, a little bit sweet and a hint of seaweed was still there.
