This tea has faded a bit in flavour since I last reviewed it (spring 2017). However it has held up a lot better than some of the other senchas. Still a good grassy umami flavour to it but lacking sweet buttery flavour when I first tried it. This year I hope to refrigerate some of my green teas in the wine cooler so they can stay fresher longer.
I can attest the refrigerator helps extend the freshness of green tea, especially Japanese greens. Airtight pouches and allowing 24 hours for the tea to come to room temperature is key.
