When the climate outdoors is chilly and grey the there’s hardly something extra comforting than a heat cup of tea. Whether or not you wish to cozy up with the sturdy, citrusy tones of an Earl Gray, the candy, floral aroma of jasmine tea or no matter your favourite brew is there’s simply one thing about sipping tea that feeds the soul. (Until you are extra of a espresso or cocoa particular person.)
Whereas a few of us discover tea soothingly tasty, chances are you’ll simply drink tea merely in your personal well-being. Many kinds of teas have been puffed up for particular health-boosting properties like: some supposedly pace up weight reduction or assist to forestall coronary heart illness, whereas others lower blood stress. That is why there are tea advocates that recommend incorporating sure teas into your food plan to satisfy your well being targets.
However, what precisely makes every tea so distinctive and what number of of those well being claims are literally true? To reply these questions, we have talked to specialists and dug into the analysis to seek out out.
What’s tea fabricated from?
Regardless of the entire styles of tea you would possibly see at your native cafe, all “true” teas — which means those that are not thought of “natural” like chamomile or hibiscus — are derived from the identical shrub that is grown everywhere in the world: the camellia sinensis plant a.ok.a. the tea camellia tree.
So, “there is not a white tea plant or a inexperienced tea plant,” says Leah Boalt Richardson, the director of World Tea Academy and the writer of Modern Tea: A Fresh Look at an Ancient Beverage. As a substitute, what offers every sort of true tea their distinct coloration and taste is the manufacturing course of, which incorporates:
- The time the leaves are harvested
- How lengthy and in what method they had been allowed to wither
- How lengthy the leaves had been oxidized or browned
Every a part of the method not solely influences the look and style of the tea, they illicit sure chemical reactions that change the micronutrients inside the leaves, in response to Richardson.
What are the well being advantages of tea?
Simply to be clear: “Tea is meals, not medication,” says Richardson. In different phrases, it has not been confirmed that tea can treatment or heal any illness or ailment. Neither is there any stable proof of tea having the ability to pace up your weight reduction journey, she provides. So do not hassle shelling any money on these so-called “fat-busting” detox teas.
However, tea does comprise vitamins that researchers say might help a nutritious diet. For instance, tea accommodates:
- Polyphenols. These act as anti-oxidants that assist to struggle the free radicals that harm your cells, according to Harvard specialists. This can be why some research means that consuming two to a few cups of polyphenol-rich tea day by day has the potential (key phrase: potential) to scale back the chance of untimely demise, heart disease, stroke and type 2 diabetes in addition to to help to lower blood pressure. However there are many research that present conflicting outcomes. One of many causes for this could possibly be as a result of polyphenol content material highly varies amongst tea varieties and types; it additionally adjustments in response to the place the tea was harvested, how the plant was grown, and the way it was processed. To not point out, if you happen to like your milk teas and lattes, the well being profit that you are going for could also be affected. Research have discovered that including milk, honey and lemon can intrude with how polyphenols work together along with your physique.
- Methylxanthine. Most of us are accustomed to essentially the most talked about methylxanthine: caffeine. It will possibly assist us get that wanted vitality increase after we are feeling sluggish or foggy. However within the case that caffeinated drinks like espresso make you are feeling too jittery, tea might give you a gentler expertise because it tends to have much less caffeine. According to specialists from the Mayo Clinic, one cup of brewed espresso has 96mg of caffeine whereas one cup of plain black tea has about 47mg. Tea additionally accommodates two different kinds of methylxanthines, theophylline and theobromine, which, whereas stimulating are each thought of muscle relaxants, in response to Richardson. This counteracts the jitteriness you would possibly really feel by simply having caffeine.
- L-theanine. This amino acid is the opposite cause why tea would not make you as wired as espresso, in response to Richardson. “It retains you alert, however it is usually very soothing,” she says. Some scientists believe it is because L-theanine has the power to move via the blood-brain barrier and enhance the alpha mind waves that are related to psychological states of alert leisure like if you’re daydreaming or meditating.
Once more, consuming lots of tea in all probability is not going to result in well being miracles, however Richardson finds that the best advantage of consuming sizzling tea is the way it encourages you to decelerate in the course of the day and practice mindfulness.
“Simply sitting quietly, consuming a cup of tea provides you with that mind-body-soul connection,” she says. “Stepping apart and giving your self ten minutes in the midst of the day can rejuvenate your thoughts.”
Varieties of wholesome “true” tea
All teas are “wholesome” teas, says Richardson — there isn’t any sort that is higher than the opposite. However, to provide you an thought of how they differ, listed here are the six kinds of true teas and what makes them style and look so distinctive:
Green Tea
Inexperienced tea leaves are picked from the camellia sinensis plant then are typically withered a bit however are all the time cooked (both pan-fired or steamed) to forestall as a lot oxidization as attainable, says Richardson. Stopping the oxidation course of in its tracks helps to protect their wealthy inexperienced coloration and the grassier style. As a result of the inexperienced tea leaves aren’t as processed as different darker teas, they tend to have larger ranges of catechin, a kind of polyphenols that fights off these pesky free radicals.
Taste: grassy, vegetal, herbaceous
Examples of inexperienced tea: Jasmine, Matcha, Genmaicha, Hojicha
White Tea
To make white tea, harvesters need to snatch the leaves when they’re very younger (even youthful than inexperienced leaf harvests). When the leaves are merely buds, they’re normally lined in “white downy fuzz”, in response to Richardson, which is the place the “white” title comes from. As soon as they’re plucked they’re dried to minimize oxidation. Like inexperienced tea, the white selection tends to have larger ranges of catechin since it’s the least processed, according to researchers.
Taste: subtlety candy, fruity, floral, mildly grassy
Examples of white tea: White Peony, Silver Needle, Shou Mei
Black Tea
What makes black tea black is the oxidation process. When the leaves are rolled then uncovered to oxygen-rich air, they start to supply theaflavin and thearubigin — antioxidant polyphenols that give the leaves their darkish pink/brown pigment. Ultimately, they seem black. Oxidation can be what helps to provide black tea its daring taste profile.
Taste: sharp, bitter, full-bodied, malty, floral
Examples of black tea: Earl Gray, Assam, English Breakfast, Darjeeling
Yellow Tea
This can be one of many least identified teas within the West since “it’s tough to supply as a result of the harvest time is brief, the processing is advanced and time-consuming, and, till lately, China was the one producer,” Richardson writes in her guide Modern Tea. Yellow tea is made with leaf buds plucked in early spring. They’re then processed like inexperienced teas via pan-firing or handled with a delicate heating methodology referred to as males huan (sealing yellow). Subsequent they’re wrapped in paper or a dampened material and left to chill earlier than probably being pan-fired once more. What number of occasions they’re pan-fired and the way lengthy they’re wrapped relies on the tea maker, however this course of can final three to 4 days, says Richardson.
Taste: candy honeysuckle and apple notes
Examples of yellow tea: Gentleman Mountain Silver Needles, Mengding Yellow Sprout, Huo Mountain Yellow Sprout
Oolong Tea
Oolong tea leaves are partially oxidized so lots of them do not fairly attain that darkish, full-bodied style of black teas, however this brew has its personal type of yummy. The style of oolong varies drastically relying on how lengthy the tea maker decides to oxidize the leaves. “The degrees of oxidation can vary wherever from as little as 10 p.c, making it comparable in look to inexperienced tea, to as a lot as 80 p.c, leading to what appears to be like like black tea,” writes Richardson.
Taste: toasty, barely candy, probably grassy, typically floral or fruity
Examples of oolong tea: Baozhong, Tung Ting, Tie Guanyin, Da Hong Pao, Bai Hao
Darkish tea (Pu’erh)
Pu’erh — which originated in Yunnan Province in China and now could be popularly referred to as “darkish tea” within the West — goes via an additional step that different teas skip: a fermentation course of that’s usually saved secret by tea makers, says Richardson. Although our lips are sealed concerning the main points (actually, we could not inform you if we wished to), normally, “fermentation is the chemical breakdown of a substance by micro organism, yeasts, or different microorganisms, usually involving effervescence and the giving off of warmth,” says Richardson. Subsequent the leaves are aged for some time — typically for years, according to specialists from Reishi Tea and Botanicals. This all offers darkish tea its uniquely sturdy taste.
Taste: earthy, easy, woodsy, barely candy
Examples of darkish tea: Shen Pu’erh, Shou Pu’erh

Briefly, if you happen to ever get curious, there’s a complete world of tea to discover.
