Matcha leaves are grown on green tea bushes kept under shade. The shade increases the amount of chlorophyll content in the leaves, which is what makes them bright green and full of nutrients. The leaves are picked by hand and the stems and veins are removed. According to Cheadle, the leaves are traditionally ground by granite stones into a super fine powder. “It takes an hour to grind the leaves, and it’s done in the dark to protect the nutrients,” she says.
Those magical catechins also have tons of potential in helping people with heart issues. “Catechins present in green tea have the ability to prevent atherosclerosis, hypertension, endothelial dysfunction, ischemic heart diseases, cardiomyopathy, cardiac hypertrophy and congestive heart failure by decreasing oxidative stress, preventing inflammatory events, reducing platelet aggregation and halting the proliferation of vascular smooth muscle cells,” explains the author of the study, published in the Chinese Journal of Natural Medicines.
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan.[60] The shading technique imparts a sweeter flavor, and produces a particularly rich color thanks to the higher amounts of chlorophyll in the shaded leaf. Gyokuro tea is associated with the Uji region, the first tea-growing region in Japan. It is often made using smaller-leaf cultivars of the tea plant.[61]
