Green tea from Japan, Gyokuro, also known as "jade dew" because of its unique blue-green color and naturally sweet taste, is the highest quality Japanese green tea . Made only with the earliest buds of the first spring flush season, Gyokuro usually grows in the shade for around 20 days before hand-harvested. Due to reduced sunlight, less photosynthesis occurs resulting in increased amounts of amino acids. chlorophyll, and caffeine. This impacts Gyokuro's color, taste and aroma producing a sweet, delicate tea with a soft, mellow body.
