Generally low quality relative to low-cost ones you can get at regular supermarket in Japan, as umami is almost entirely lacking and simply bitter. If you are bying from oversea, it is not too pricy, but if buying in Japan, jsut go to regular store and buy cheap sencha there - it is much cheaper and taste better than way.

Thank you for your comment!
Sencha of the Wind is a first flash spring harvest of Kabuse Sencha, a ZAIRAI(sead grow) variety of green tea. The tea has a wild taste and a hint of sweetness that can only be found in ZAIRAI. We recommend brewing the tea with lukewarm water (70-80 degrees Celsius) or by cold brew it slowly. The temperature of the tea may greatly affect the taste, so please enjoy the tea at various temperatures. We hope to you are enjoy this tea again! Thank you.
