Quick answer
Green tea is one of the least processed teas, which is known to retain catechins like EGCG, the amino acid L-theanine, and a range of other antioxidants. Studies link regular green tea consumption to healthier gums, better heart markers, calmer focus, and a small boost in metabolism. Steep it at around 175°F for one to three minutes and you may get those benefits without the bitterness.

Green tea has been part of daily life in China for more than 4,000 years, and for good reason. Because the leaves undergo minimal processing, they retain many of their naturally occurring compounds, including chlorophyll, amino acids, and catechins. That gentle approach to production is one reason green tea has remained a focus of wellness and nutrition research for decades.
Below are seven reasons green tea has remained a daily ritual for centuries. You'll learn how much caffeine is in a cup, the ideal water temperature for a smooth, balanced brew, and where to start if you're new to green tea. For a deeper look at its origins and production, read our guide to what green tea is and how it is grown.

Every true tea, green, black, oolong, and white, comes from the same plant: Camellia sinensis. What separates them is processing. As soon as green tea leaves are picked, they are heated right away to stop oxidation, the browning reaction that turns other leaves dark. Stopping that reaction early is the whole trick. It keeps the leaf green and preserves the delicate compounds that give green tea its reputation.
One of green tea's most notable naturally occurring compounds is catechins, a group of plant antioxidants found in especially high concentrations. The most researched of these is epigallocatechin gallate (EGCG). Because green tea undergoes minimal oxidation during processing, it retains more of these catechins, making it a continued focus of nutrition and wellness research.
Another key compound found in green tea is L-theanine, a naturally occurring amino acid. This amino acid is found almost only in tea, and it is responsible for that calm, clear-headed feeling a good cup gives you. L-theanine is the reason green tea can wake you up without the hard edge of coffee.
How green tea is made, and why it changes the cup
That first heating step is typically done using one of four methods: steaming, pan firing, baking, or wok-roasting over wood or charcoal. While the technique often reflects regional tradition, it has a significant impact on the finished tea, shaping its color, aroma, and flavor from the very first sip.
In Japan, green tea is usually steamed, which locks in a vivid grassy-green color and a fresh, vegetal taste. Our Japanese Sencha is a classic example, bright and clean with a crisp finish. China traditionally pan-fires or wok-roasts its leaves instead, turning them a paler, toastier green with nutty, mellow notes. Our pan-fired Dragonwell is smooth, gently sweet, and has a chestnut edge.
Good to know: If a green tea tastes grassy and briny, it was probably steamed. If it tastes nutty and toasty, it was probably pan-fired or roasted. Neither is better. Understanding the difference simply makes it easier to find the styles you'll enjoy most.
7 research-backed benefits of green tea
Green tea is one of the most extensively studied beverages in the world. While research is ongoing, studies suggest it may offer a range of potential wellness benefits when enjoyed as part of a balanced lifestyle. Here are seven areas researchers continue to explore.
1. It is known to support healthier teeth and gums
Some research from the American Academy of Periodontology has explored an association between regular green tea consumption and markers of oral health, including gum health. Researchers believe green tea's naturally occurring catechins and other plant compounds may play a role, though more research is needed to better understand the relationship. Green tea can be a flavorful addition to a balanced routine, but it is not a substitute for regular brushing, flossing, and professional dental care.
2. It is rich in naturally occurring antioxidants
Green tea is naturally rich in catechins, a group of plant compounds with antioxidant properties. EGCG is the most widely studied of these catechins, and researchers continue to explore its potential role in overall wellness. If you're curious how green tea compares to other tea varieties, explore our guide to the teas with the highest antioxidant content.
3. It has been widely studied for heart health
Green tea has been the focus of numerous studies exploring cardiovascular wellness. Researchers continue to investigate how its naturally occurring flavonoids and catechins may support healthy cholesterol metabolism and blood vessel function as part of an overall healthy lifestyle. While no single food or beverage determines heart health, green tea remains one of the most extensively researched.
4. It may support an active lifestyle
Green tea is often associated with metabolism, though the research suggests any effects are modest. Scientists continue to study how the combination of naturally occurring caffeine and EGCG may influence energy expenditure. Whether you're looking for an afternoon pick-me-up or simply looking to replace a sugary beverage, green tea is an easy addition to your daily routine.
5. It offers calm, balanced energy
One of green tea's defining characteristics is the combination of naturally occurring caffeine and L-theanine. Together, these compounds are thought to contribute to the calm, focused feeling many people associate with green tea. Rather than an intense jolt of energy, many tea drinkers enjoy a smoother, more balanced lift.
L-theanine, combined with a little caffeine, is why green tea wakes you up without winding you up.
6. Matcha delivers the whole leaf
Unlike traditional green tea, where the leaves are steeped and removed, matcha is stone-ground into a fine powder and whisked directly into water, so you consume the entire leaf. Because of this, matcha naturally contains higher levels of compounds found in green tea, including catechins and L-theanine, as well as more caffeine per serving. Our Matcha+ blend and convenient Matchasticks make it easy to enjoy every day. If you're new to matcha, explore our complete guide to matcha green tea or learn how matcha compares to traditional green tea.
7. There is a green tea for every palate
The best green tea is the one you'll look forward to brewing again tomorrow. Fortunately, there's a style for nearly every preference. Some green teas are fresh and vegetal, while others are mellow and nutty. You'll also find floral, citrus, and fruit-forward blends that bring a completely different character to the cup.
Traditional Japanese Sencha offers a bright, grassy profile, while our award winning Green Pomegranate delivers vibrant fruit notes with a smooth green tea base. Wherever your preferences fall, there's a green tea worth discovering.

Join the Tea ClubHow much caffeine is in green tea?
A typical 8-ounce cup of green tea contains roughly 25 to 35 mg of caffeine, less than half the amount you get from the same amount of coffee, which usually contains 95 mg. For most healthy adults, enjoying two to three cups of green tea each day fits comfortably within the amount commonly examined in research. Individual caffeine tolerance varies, so the amount that's right for you may be different.
Matcha has a higher concentration, closer to 60 to 70 mg per serving, because you drink the whole ground leaf rather than an infusion. Hotter water and longer steeps pull out more caffeine, so your brewing choices matter as much as the leaf. For a full breakdown across every tea type, see our guide to the caffeine content of tea.
How to steep green tea so it never tastes bitter
If green tea has ever tasted harsh or astringent to you, the leaf was almost never the problem. The water was too hot. Green tea is delicate, and boiling water scorches the leaves and draws out bitter tannins. Dial the temperature down, and the same tea turns sweet, smooth, and forgiving.
Aim for about 175°F and a steep of one to three minutes. No thermometer? Boil your kettle, let it sit for two minutes before pouring, or splash in a little cold water. Most green teas re-steep two or three times, and the second infusion is often the sweetest. Our list of recommended steep times is a handy reference to keep near the kettle.
| Green tea style | Water temp | Steep time | What to expect |
|---|---|---|---|
| Steamed (Sencha style) | 160 to 175°F | 1 to 2 min | Bright, grassy, crisp |
| Pan-fired (Dragonwell style) | 175 to 185°F | 2 to 3 min | Nutty, mellow, sweet |
| Fruit-blended green | 175°F | 2 to 3 min | Juicy, aromatic, smooth |
| Matcha (whisked) | 175°F | Whisk, no steep | Rich, creamy, umami |
How much green tea should you drink a day?
For most healthy adults, two to three cups a day is a comfortable amount that lines up with much of the research on green tea's benefits. That range gives you a steady supply of catechins and L-theanine without piling on caffeine.
A few sensible caveats. If you are caffeine-sensitive, pregnant, or nursing, check with your doctor about the right amount for you. Green tea can also be rough on an empty stomach, so pairing it with food helps. The sweet spot is moderation, not chugging a pot before noon.
Where to start: green teas worth trying
If you're not sure where to begin, here are a few favorites we'd recommend. For a classic Japanese green tea, Sencha offers a bright, grassy profile with a clean finish. Prefer something softer? Our pan-fired Dragonwell is smooth, mellow, and gently nutty, making it an easy everyday cup.

Frequently asked questions
Is it better to drink green tea in the morning or at night?
Morning or early afternoon works well for most people since green tea naturally contains caffeine. Many people enjoy the balanced character created by green tea's naturally occurring caffeine and L-theanine.
Does green tea actually help with weight loss?
Green tea is not a weight-loss cure, but the combination of caffeine and EGCG is known to give your metabolism a small, temporary lift. It is best used as a low-calorie alternative to sugary drinks as part of a balanced diet, not as a standalone diet plan.
Why does my green tea taste bitter?
The most common cause is water that is too hot, which scorches the leaves and pulls out bitter tannins. Steep green tea at around 175°F for one to three minutes instead of using boiling water. Over-steeping and stale leaves can also cause bitterness.
Is matcha healthier than regular green tea?
Matcha and traditional green tea both come from the same plant. Because matcha is made by whisking finely ground tea leaves into water, you consume the entire leaf, resulting in higher amounts of naturally occurring catechins, L-theanine, and caffeine per serving. Both can be enjoyed as part of a balanced diet.
How much green tea is safe to drink each day?
For most healthy adults, two to three cups per day is common. If you're pregnant, nursing, caffeine-sensitive, or have questions about caffeine intake, consult your healthcare provider.
