Loose leaf green tea stands as one of the world's most favored beverages, especially among health-conscious individuals. Renowned for its manifold benefits for both the body and mind, including metabolism boost, mood enhancement, infection prevention, and inflammation reduction, it holds a significant place in wellness routines. Yet, amidst its virtues, does loose leaf green tea influence the body's pH level? Is it acidic or alkaline? And why does this aspect matter?
In this article, we delve into these queries and beyond. Exploring the intricacies of pH, its impact on well-being, and how various types of loose leaf tea can distinctly influence your body's pH equilibrium. Additionally, we'll furnish invaluable insights on savoring loose leaf green tea without compromising dental or stomach health.
What is pH and Why is It Important?
pH is a measure of how acidic or alkaline a substance is. It ranges from 0 to 14, with 7 being neutral. Anything below 7 is acidic, and anything above 7 is alkaline.
The pH of your body fluids, such as blood, saliva, urine, and stomach acid, is tightly regulated by your body to maintain optimal health. The normal pH range for blood is between 7.35 and 7.45, which means slightly alkaline. If your blood pH falls below or above this range, it can cause serious health problems, such as acidosis or alkalosis.
The pH of your stomach acid is much lower than that of your blood, usually between 1.5 and 3.5. This is necessary to digest food and kill harmful bacteria. However, if your stomach acid becomes too acidic, it can cause acid reflux, heartburn, ulcers, and gastritis.
The pH of your saliva and urine can vary depending on what you eat and drink, as well as other factors such as stress, medication, and exercise. The normal pH range for saliva is between 6.5 and 7.5, while the normal pH range for urine is between 4.5 and 8.
pH Levels of Different Types of Tea
Different teas exhibit diverse pH levels, indicating their acidity or alkalinity:
- Green tea: Features pH levels ranging between 7 and 10
- Black tea: pH ranges between 4.99 and 5.55
- Oolong tea: pH spans from 5.9 to 8.2
- Herbal tea: Typically falls within a pH range of 6 to 7
- White tea: Exhibits pH levels varying from 6.9 to 9.7
- Pu-erh tea: Generally falls within a pH range of 4.5 to 5.5
- Chamomile tea: Shows pH levels averaging between 6.8 and 7.5
- Rooibos tea: Typically ranges from pH 5.5 to 7
According to the preceding list, green tea is more alkaline than acidic.
Dilution with neutral substances such as water or milk is frequently used to balance acidity in tea. Shorter steeping times dramatically lower acidity, with teas releasing more acid after five minutes and climbing significantly after 15 minutes. Optimal taste characteristics in loose leaf tea normally develop after 2 to 5 minutes of steeping.

What Does Green Tea Taste Like?
Green tea of China has a subtle, yet distinctive flavor that sets it apart from other types of tea. On the first sip, you may notice that it tastes slightly bitter or astringent. This is due to the polyphenols naturally present in green tea. However, the bitterness is mild and often balanced by grassy, vegetal notes.
Since green tea has a mild flavor, it is best consumed without any additional ingredients like milk or sugar. This lets the delicate tastes come through. On the palate, you might detect notes of springtime or just cut grass. Occasionally, there are also subtle hints of spiciness that are reminiscent of black pepper. The flavor of the vegetables is light and pleasant, never overbearing. Good Chinese green tea has a far more subtle, nuanced flavor than black tea, which can have a strong, overpowering flavor. Tannins that coat the lips gently provide a clean, although slightly crisp, finish. Green tea is different from other tea varietals in that it has a light, naturally complex flavor profile. This makes it an acquired taste for some people.
How Long to Steep Green Tea?
The steeping time for good Chinese green tea can vary depending on personal preference, the specific type of green tea, and the desired strength of the tea. In general, it is recommended to steep green tea for around 2 to 3 minutes.
Steeping green tea for too long may result in a bitter taste, so it is important to keep an eye on the steeping time. If you prefer a milder flavor, you can start with a shorter steeping time of around 1 to 2 minutes. On the other hand, if you prefer a stronger and more robust flavor, you can extend the steeping time to 3 to 4 minutes.
Frequently Asked Questions
How Does Green Tea Affect Your pH Level?
Green tea is made from the leaves of the Camellia sinensis plant, which are steamed or pan-fried to prevent oxidation. This process preserves the natural antioxidants and polyphenols in the tea leaves, which give loose leaf green tea its distinctive color and flavor.
Green tea contains several organic acids, such as citric acid, malic acid, oxalic acid, and ascorbic acid (vitamin C). These acids contribute to the taste and aroma of green tea, but they also lower its pH level. The average pH of loose leaf green tea is around 7-10, which means slightly acidic.
However, the acidity of green tea can vary depending on several factors, such as:
- The type of green tea: Different varieties of green tea have different levels of acidity. For example, sencha green tea has a pH of around 5.5, while matcha green tea has a pH of around 7.
- The brewing method: The longer you steep the tea leaves in hot water, the more acidic the tea becomes. For example, steeping green tea for 3 minutes can result in a pH of around 6.5, while steeping it for 10 minutes can result in a pH of around 4.5.
- The water quality: The pH of the water you use to brew the tea can also affect the acidity of the tea. For example, using distilled water can result in a more acidic tea than using tap water or mineral water.
- The additives: Adding sugar, honey, lemon juice, milk, or cream to your green tea can also change its pH level. For example, adding lemon juice can lower the pH of green tea by about 0.5 units.
How Can I Reduce the Acidity of My Green Tea?
If you are concerned about the acidity of your green tea and its potential effects on your teeth or stomach, there are some ways you can reduce it or neutralize it.
Here are some tips:
- Choose a less acidic type of green tea: As mentioned above, different varieties of green tea have different levels of acidity. You can opt for matcha green tea or other alkaline teas such as rooibos or herbal teas.
- Brew your green tea for a shorter time: The longer you steep your green tea in hot water, the more acidic it becomes. You can reduce the brewing time to 2 minutes or less to keep the acidity low.
- Use filtered or mineral water: The quality of the water you use to brew your green tea can also affect its acidity. You can use filtered or mineral water.
What Is the Difference Between Green Tea and Matcha?
While both green tea of China and matcha come from the Camellia sinensis plant, there are some key differences in how they are processed and prepared. Green tea is made by pan-frying or steaming fresh tea leaves to prevent oxidation, which halts fermentation. The leaves are then dried, and hot water is poured over steeped leaves to make a beverage. Matcha, on the other hand, is shade-grown tender tea leaves that are then ground into a bright green powder.
The processing of matcha into a powder allows the entire leaf, including the antioxidant-rich cell walls, to be consumed. This results in matcha having up to 10 times the EGCG and antioxidants of regular brewed green tea. Additionally, matcha is prepared by whisking the powder into hot water, as opposed to steeping and removing tea leaves. This means matcha provides a full-body experience of color, texture, flavor and nutrients with each drinking. Due to using the entire leaf, matcha also has a bolder, creamier texture and notably more pronounced savory- Umami flavor than steeped green tea.
Does Green Tea Stain Your Teeth?
Good Chinese green tea often escapes the blame for tooth staining when compared to several daily consumables. Its higher alkalinity suggests that the teeth stains typically witnessed might have roots elsewhere in your dietary choices.
The acids present in items like citrus fruits, candies, fizzy beverages, tomato sauces, wines, and vinegars pose a more substantial risk. They tend to erode tooth enamel, paving the way for potential discoloration. And let's not overlook coffee, a notorious player in altering the mouth's pH balance and amplifying teeth's vulnerability to stains from other foods.
Novel insights hint at potential remedies to mitigate green tea's staining propensity. A dash of milk or cream in your tea might counteract its staining tendencies, as per certain studies. Alternatively, incorporating raw veggies into your routine may build an oral defense against staining. However, if veggies don't align with your cup, a post-tea brushing ritual could serve as your safeguard.
What Is Catechins?
Catechins are a type of antioxidant found in tea leaves. They are polyphenols that belong to a group of natural plant chemicals known as flavanols. Green tea of China, white tea, oolong tea and black tea all contain various amounts of catechins.
The major catechins found in tea are epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC). EGCG is believed to be the most potent catechin and makes up around 50-80% of total catechins in green tea.
Catechins are thought to provide many health benefits due to their powerful antioxidant properties. As antioxidants, they fight free radicals and help prevent oxidative stress-related damage to cells. Catechins have been studied for their potential ability to help reduce risks of heart disease, neurodegenerative conditions, and some cancers. They may also aid weight loss and help control blood sugar levels.
Does Green Tea Make You Poop?
Because good Chinese green tea contains caffeine and catechins, there is some evidence that it may stimulate the intestines and encourage bowel regularity. The well-known stimulant caffeine has the ability to both relax and contract the intestines. Additionally, it causes the gallbladder to contract more, which facilitates the passage of food through the digestive system.
Green tea's catechins, meantime, have been demonstrated to have prebiotic properties that promote the development of beneficial bacteria in the gut microbiota. This promotes better digestion and, by adding volume, may soften stools. According to studies, drinking green tea can help shorten the time waste takes to pass through the bowels.
Individual reactions differ, though. Within an hour of consuming green tea of China, some people may notice a minor loosening of the stool or an increase in the number of bowel movements, while others may not notice any changes at all. Results can be affected by variables such as intestinal health, current diet, and caffeine tolerance. Green tea has modest laxative effects for most people. However, it does provide many people with minor digestive help by encouraging regularity.
Does Green Tea Expire?
Yes, green tea of China does eventually expire, but the expiration timeline depends on several factors. Properly stored high-quality green tea can stay fresh for 1-2 years. Some factors that affect the shelf life include:
●Processing method: Loose leaf tea tends to last longer than tea bags since it's not enclosed. Oolong and white teas expire more quickly than green tea.
●Storage conditions: Tea should be kept in an airtight container in a cool, dark place away from heat, light, and moisture. Refrigeration further extends shelf life.
●Natural oils: The aromatic oils in tea can become rancid over time, changing the flavor. Higher-oil teas like matcha may expire faster.
●Humidity: Too much moisture can cause tea to stale more rapidly. Proper drying after production is important.
●Quality: Fresher, higher-grade tea with fewer broken leaves will maintain freshness longer.
Tea that is past expiration may taste stale, musty, or weak in flavor rather than bright and bold. Color changes are also a sign it's no longer at peak freshness. It's best to drink tea within 1-2 years for optimal taste and benefits.
Is Drinking Green Tea Good or Bad for Your Health?
Drinking green tea of China can have both positive and negative effects on your health, depending on how much you drink and how sensitive you are to its acidity.
On the positive side, drinking green tea can:
- Provide antioxidants and polyphenols that protect your cells from oxidative stress and inflammation.

- Improve your mood and cognitive function by boosting dopamine and serotonin levels in your brain.
- Prevent infections and diseases by inhibiting bacterial growth and viral replication.
- Lower your blood pressure and cholesterol levels by relaxing your blood vessels and reducing inflammation.
- Reduce your risk of cancer by modulating gene expression and inducing apoptosis (cell death) in tumor cells.
On the negative side, drinking too much green tea or drinking it on an empty stomach can conduct to stomach irritation, causing nausea or discomfort due to its relatively high caffeine content. Excessive consumption, especially on an empty stomach, can prompt acid reflux or exacerbate existing gastrointestinal issues.
Finding a balance in green tea consumption is crucial for reaping its benefits while mitigating potential drawbacks. Overindulgence may lead to disrupted sleep patterns, jitteriness, or even increased anxiety in sensitive individuals due to its caffeine levels. Moreover, the acidity in green tea might pose challenges for those with acid reflux or sensitive stomachs, causing discomfort when consumed in large quantities or on an empty stomach.
Moderation is key; consuming moderate amounts of green tea, typically around 3-4 cups a day, allows individuals to harness its health benefits without experiencing adverse effects. Additionally, taking breaks between cups or consuming it alongside meals can help buffer its acidic impact on the stomach.
Does Green Tea Have Caffeine?
Indeed, green tea of China contains caffeine, albeit in milder doses compared to coffee. An 8-ounce cup typically carries around 35 mg of caffeine, offering a gentle pick-me-up without the potent jolt often associated with coffee's higher caffeine levels.
Is Green Tea More Acidic Than Coffee?
In the realm of acidity, green tea stands apart from coffee. Generally boasting lower acidity levels, green tea occasionally tilts towards alkalinity, showcasing pH levels reaching as high as 10. Yet, the precise acidity varies based on brewing techniques and any added elements. It's crucial to note that certain bottled green teas might up their acidity due to added sugars or additives. Furthermore, green tea also contains caffeine, which can aggravate acidity and cause side effects in excess. Aim to consume green tea in moderate amounts if you're an otherwise healthy individual.
How to Brew Green Tea?
Tea utensils:
Unlike other Chinese teas, green tea is better brewed in a glass.
Because the beauty of green tea is not only in the taste, but also in the fact that when green tea is brewed, the tea leaves come down from the sky like a fairy dancing with long sleeves.
Therefore, using glass cups to brew famous teas makes it easier to appreciate the appearance and inner texture of the tea leaves.
Water temperature:
Green tea is usually delicate, usually the water temperature for green tea is between 80℃-90℃.
Of course, different green tea will have different methods, according to the grade of green tea, tenderness and so on, there are three different brewing methods: up-throw method, middle-throw method and down-throw method.

The impact of green tea on fasting can vary based on the type of fast and individual circumstances. Generally, plain green tea without any additives like sugar or milk is considered non-caloric and low in calories, containing minimal to no macronutrients.
During intermittent fasting or certain fasting protocols like water fasting, consuming plain, unsweetened green tea is often permitted without significantly disrupting the fast. Its low-calorie content and potential benefits, like antioxidants, may not trigger an insulin response or substantially interfere with the fasting state for many individuals.
Does Green Tea Help with Bloating?
Yes, green tea is believed to help with bloating for several reasons:
- Natural Diuretic: Green tea acts as a natural diuretic, aiding in reducing water retention in the body. This can help alleviate the feeling of bloating caused by excess water.
- Anti-inflammatory Properties: Green tea contains antioxidants that possess anti-inflammatory properties. Bloating can sometimes be due to inflammation in the digestive system, and these properties may help in reducing that discomfort.
