Tealux Gyokuro Kokyo is a solid Japanese green, no doubt, but I found it to be a bit flat when compared directly side-by-side with Gyokuro Premier. The dark, roasted-spinach-like dried leaves were very similar in appearance, as was the brewed liquor—both were very pale green with tiny white particles floating about.
The texture of the Gyokuro Kokyu was not as smooth as that of Gyokuro Premier, and I felt that the blend was closer to sencha than to Gyokuro. It is a blend of two teas, basically Gyokoru has been cut with a less-expensive tea to produce a cost-effective Gyokuro. I am not convinced that the savings (only a $2 difference between 1 ounce of pure Gyokuro and 1 ounce of this blend) are worth this change…
Interestingly, I have encountered of late a couple of Gyokuro-esque senchas, so I’ll have to compare this blend side-by-side to see which I prefer!
