Grassy and Vegetal are definitely two of the words that can be used to describe this tea.
One of my favorites, I like to steep it for either 45 seconds, or 2 minutes using 175 degree Fahrenheit water. Interestingly enough, if you steep the Gyokuro for 45 seconds, it manages to produce a strong flavor, while keeping the bitter qualities of tannin’s completely out of the mixture. Any longer than 45 seconds, and the tannin’s flavor is obvious; however, at 2 minutes, the bitterness once again diminishes and you are left with an even stronger flavor than with 45 seconds, while still managing to escape the tannin’s flavor. I have also tried Gyokuro iced, though I much prefer the traditional flavors hot.
Gyokuro is a lovely escape into a grassy field on a dew filled morning. I would highly recommend this tea to any green tea lover, with a special spot for Vegetation. I also believe that Matcha powder is made from crushed young Gyokuro leaves.
