Matcha is green tea that has been specially grown and processed. Twenty days before harvest, the leaves are shaded from direct sunlight, which amps up the chlorophyll levels (and accounts for that Kermit green color) and increases the production of the amino acid L-Theanine, which is thought to promote relaxation even as the tea gives you a caffeine jolt. The leaves are hand-picked and laid out to dry. Once they are rid of their veins and stems, they’re stone-ground into what is finally matcha.
Japanese green teas have a thin, needle-like shape and a rich, dark green color. Unlike Chinese teas, most Japanese teas are produced by steaming rather than pan firing. This produces their characteristic color, and creates a sweeter, more grassy flavor. A mechanical rolling/drying process then dries the tea leaves into their final shape. The liquor of steamed Japanese tea tends to be cloudy due to the higher quantity of dissolved solids.
The use of matcha in modern drinks has also spread to North American cafés, such as Starbucks, which introduced "Green Tea Lattes" and other matcha-flavoured drinks after matcha became successful in their Japanese store locations. As in Japan, it has become integrated into lattes, iced drinks, milkshakes, and smoothies. A number of cafes have introduced lattes and iced drinks using matcha powder. It has also been incorporated into alcoholic beverages such as liqueurs and matcha green tea beers.
According to a study published in the journal Chinese Medicine, many of the beneficial biological effects of flavonoids on heart health seem to be due to cell-signaling effects that lower inflammation. (6) Not only do flavonoids have anti-inflammatory capabilities, but they’re also antithrombogenic, antidiabetic, anticancer and neuroprotective compounds.
Matcha, like other green teas, contains a class of antioxidants called catechins. Matcha is high in a catechin called EGCG (epigallocatechin gallate), which is believed to have cancer-fighting effects on the body. Studies have linked green tea to a variety of health benefits, like helping to prevent heart disease, type 2 diabetes and cancer, and even encouraging weight loss. However, it’s important to note that much of this research isn’t from clinical trials that show green tea causes a benefit. Instead, it’s largely from population-based studies, where researchers look at groups of people who drink green tea and compare their health outcomes to groups that don’t drink it. Studies have shown associations between tea and better health, but causation is not yet proven. Matcha is even less studied than brewed green tea.
In 2004, scientists at the University of Newcastle studied the effects of black and green tea on Alzheimer’s disease. In laboratory studies, both teas prevented the breakdown of acetylcholine, the neurotransmitter strongly linked with memory. The teas also inhibited enzymes known as BuChE and beta-secretase. These enzymes are found in protein deposits found in the brain of Alzheimer’s patients. (7)
Matcha tea rich in EGCG helps fight various bacterial, viral, and fungal infections. According to a research study, EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.
Ceremonial grade: This is the highest quality used mainly in tea ceremonies and Buddhist temples. This is stone-ground into a powder by granite stone mills. It is high-quality and expensive (~$100–140 for 100g). The unschooled drinker is unlikely to notice a large difference between Ceremonial and Premium grade. Ceremonial is characterized by subtle tones of "umami".
It all started out at the top of the year when I ordered a very popular detox tea that I saw promoted heavily on Instagram. I’d seen this product advertised by just about every pretty face and snatched body in the industry. I read no real complaints, however, when I went to the company’s website, I did notice a few customer reviews warning new drinkers to steep their tea for less than the recommended time. Basically, the instructions said to steep for four minutes, but some suggested only steeping one to two minutes max. Ladies also warned that bad cramping was inevitable, but I thought, as a grown woman, what cramp have I not experienced by now?
According to science, matcha is something of a miracle supplement. For one, it makes you feel good. One recent study examined the effects of the phytochemicals in green tea on mood and cognition. The combo of caffeine (present in most green teas) and L-theanine, an amino acid found in some teas, were found to “improve performance in attention-switching tasks and alertness, but to a lesser extent than caffeine alone,” partly because of how L-theanine chills you out.
Rooibos tea is anti-inflammatory in nature, which means that it reduces blood pressure and scavenges free radicals like other antioxidants. Quercetin, another powerful antioxidant found in rooibos tea, has been linked to preventing a wide variety of heart conditions. It promotes an increase in HDL cholesterol (good cholesterol) and inhibits the LDL cholesterol (bad cholesterol) from binding to the walls of arteries and blood vessels.
