Marukyu Koyamaen Premium Ceremonial Grade Matcha [Japan][Multiple Grades] (Yugen, 20g)

I purchased the Wako Marukyu-Koyamaen matcha and it was my very first experience with matcha tea. I finished my first container and only prepare it traditionally with hot, never boiling, water (not lattes, smoothies, etc.). This tea has been excellent and the taste, bright green color, and consistency has been absolutely superior to KENKO tea I also purchased at the same time. Because it is such a night and day difference in flavor between the tasty Marukyu-Koyamaen and the KENKO (Australian Company) that am going to try to determine if the KENKO is somehow stale or tainted.If this Wako tea was so excellent, I can imagine how tasty the prized Marukyu-Koyamaen Tenju is and I desperatetly want to try it and will buy it.
