Is Green Tea Alkaline Or Acidic? What You Should Know
Let’s settle the debate, is green tea alkaline or acidic?
Green tea is one of the most enjoyable beverages and has many health benefits. Some people believe it has an alkalizing effect on the body, while others argue it is acidic.
Whether green tea is alkaline or acidic is important because it can help you make healthier choices.
Green tea has a pH of around 7 to 10, making it slightly alkaline. Since green tea is slightly alkaline, it can help restore the body’s pH balance and improve overall health.
In this blog post, I’ll explore the science behind whether green tea is acidic or alkaline and what that means for our health. You’ll learn about how green tea affects your body and different teas that are more alkaline.
What Is The pH Scale?
The pH scale measures how acidic or alkaline a substance or solution is. It’s a scale ranging from 0 to 14, with 7 considered neutral.
Foods and beverages with a pH lower than 7 are considered acidic, and solutions with a pH higher than 7 are considered alkaline.
A solution can be classified as weakly acidic, weakly basic, or strongly acidic/basic, depending on how close its pH is to the neutral value of 7.
Knowing the acidity of different beverages can help you make better nutritional decisions. Certain nutrients and minerals can be impacted by an overly acidic or alkaline environment in the body.
What Is The Difference Between Alkaline And Acidic?
Knowing the difference between alkaline and acidic foods is important to help with proper digestion and keep your body balanced.
It’s commonly known that acids and bases, or alkalis, are both important diet components. A healthy diet should have a balance between these two components.
Alkaline refers to a pH level between 7.36 and 14. Acidic refers to a pH level below 7. Anything above 7 is considered alkalizing, while anything below is considered acidifying.
When reading the pH scale, remember that the difference in numbers represents a tenfold difference in acidity. For example, a pH of 4 is 10 times more acidic than a pH of 5. This means lemon juice with a pH between 2 and 3 is 10,000 to 100,000 times more acidic than water.
Is Green Tea Alkaline or Acidic?
When it comes to whether green tea is acidic or alkaline, it’s worth noting that it falls into both categories, depending on your brewing method.
Green tea is considered to be slightly alkaline because of its pH value between 7 to 10. However, it does have some acidic properties because it contains tannins which is the reason for the bitter and astringent flavor.
If you’re sensitive to acidity, here’s what you can do to reduce the pH level:
- Use filtered water rather than tap water because tap water may contain minerals that could affect green tea’s flavor.
- Steep for the appropriate time and avoid steeping for too long, which can increase acidity and create a stronger taste.
One way to tell if tea is acidic or alkaline is by taste. Typically teas with a tart or sour taste will be more acidic.
What Is The pH Level Of Green Tea?
Green tea has a moderate pH of 7 to 10. This is considered slightly alkaline but also leaning towards more neutral. The acidity of your cup of green tea will depend on several factors, such as the type of green tea and how it was prepared and brewed.
Factors That Affect the Acidity of Green Tea
Here are several factors that can affect the acidity level of green tea. Although you can mostly control the water temperature and brewing method, the growing and process conditions are much more difficult to influence.
Growing Conditions
The acidity of green tea begins with the growing conditions. The pH of the soil plays a crucial role, as it affects the tea plant’s nutrient uptake.
Properly balanced soil pH enhances tea quality. Additionally, the water used for irrigation and the type of fertilizer applied can also influence acidity levels.
Processing Methods
The way green tea leaves are processed impacts their acidity. Oxidation levels, for example, affect tea’s acidity – the less oxidized, the less acidic.
Green tea undergoes minimal oxidation due to its unique steaming process, preventing the leaves from becoming overly acidic.
Preparation Methods
The way you prepare green tea can alter its acidity. The key factors are:
- Water temperature: Lower water temperatures (around 70-80°C) provide a smoother, less acidic taste.
- Steeping time: A shorter steeping time (1-3 minutes) prevents excessive acidity and keeps green tea’s fresh flavor.
Brewing a balanced green tea depends on perfecting each step, from soil to cup.
The Average pH Level of Different Types of Teas
Different types of teas have a variety of pH levels. Each type has different chemical components, and varying amounts of these components cause the pH level to differ.
To give you a clearer picture, we’ve compiled a comparison table of the top ten most popular teas and their respective pH levels.
| Tea Type | pH Level |
| Green Tea | 7 – 10 |
| Black Tea | 4.9 – 5.5 |
| Oolong Tea | 5.3 – 6 |
| White Tea | 6 – 7 |
| Herbal Tea | Varies (5.5 – 10) |
| Rooibos Tea | 4.5 – 5.5 |
| Chai Tea | 5 – 6.5 |
| Mate Tea | 5 – 6.5 |
| Yellow Tea | 6 – 7 |
| Pu-erh Tea | 4.5 – 6 |
These pH levels are approximate values as they may vary depending on the specific blend, tea processing, and brewing techniques.
Generally, green and white teas are considered to be more alkaline, whereas black and oolong teas tend to be more acidic. This is due to the lower oxidation levels of both green and white teas compared to their black and oolong counterparts.
Additionally, herbal teas can have a wide range of pH levels, depending on the ingredients used in the blend. For example, hibiscus tea leans more acidic, while peppermint tea is more alkaline.
Is Green Tea More Acidic Compared to Coffee?
When it comes to acidity, green tea is generally less acidic than coffee. To put this into perspective, let’s look at the pH scale, which ranges from 0 (extremely acidic) to 14 (extremely alkaline), with 7 being neutral:
| Beverage | pH Range |
| Green Tea | 7 to 10 |
| Coffee | 4.85 to 5.10 |
As you can see, green tea falls on the alkaline side of the pH scale. This is beneficial, as alkaline foods and beverages can help to offset the acidic effects of other drinks or foods. Whereas coffee is more acidic so moderation is key.
Is Green Tea More Acidic Compared to Black Tea?
When comparing green tea and black tea, there are some distinctions. Although both teas come from the same plant, Camellia sinensis, their processing methods differ, which impacts their acidity levels.
Green tea is steamed or pan-fired, retaining its natural color. In contrast, black tea undergoes fermentation and oxidation, which turns the leaves a darker shade. Now, let’s have a look at the pH scale:
| Type of Tea | pH Level |
| Green Tea | 7-10 |
| Black Tea | 4.9 – 5.5 |
As seen in the table above, green tea has a slightly alkaline pH level, while black tea is notably more acidic. If you’re sensitive to acidic beverages, green tea might be your ideal choice for a soothing and subtle cup of tea.
Does Green Tea Stain Your Teeth?
Yes, green tea can stain teeth because it contains an antioxidant called tannins. Tannins are the source of the bitter and astringent taste. They are natural plant compounds that can cause discoloration.
However, the extent of staining depends on several factors, such as the brewing method and water temperature. Hot water or longer steeping times will cause a higher chance of teeth stains.
