Is Matcha Acidic? A Tea Expert Solves the pH Puzzle

Is matcha acidic? 🤔

This is something a lot of people ask, especially if they are concerned with their health. Eating acidic foods may contribute to acid reflux, erosion of tooth enamel, and increased risk of certain health conditions. So is matcha one of these foods?

In this article, we’ll answer the question is matcha tea acidic once and for all. We’ll also get to the bottom of a lot of the stubborn matcha myths when it comes to acidity, health and more.

Let’s get started! 🍋


Is Matcha Acidic or Basic?

Before we answer the question, it’s important to go through a quick middle school chemistry lesson. Substances are either basic (alkaline) acidic or neutral. This is determined by measuring the substance on the pH scale.

PH scale

The pH scale is a numerical representation of how acidic or alkaline a substance is, ranging from 0 to 14. A pH value of 7 is considered neutral, while values below 7 indicate acidity, and values above 7 indicate alkalinity. The lower the pH value, the more acidic the substance is, and vice versa.

How Acidity is Measured

Acidity in beverages and foods is determined by measuring the concentration of hydrogen ions present in the substance.

A higher concentration of hydrogen ions results in lower pH values, indicating higher acidity. Conversely, a lower concentration of hydrogen ions results in higher pH values, indicating alkalinity.

In the context of matcha, understanding the pH scale is crucial to evaluate whether this green tea variety is acidic or alkaline and how it compares to other beverages and foods. Matcha is generally considered to be slightly acidic or neutral, with a pH level ranging from around 5.5 to 7.0.


Is Matcha Tea Acidic?

Matcha is generally considered to be slightly acidic, with a pH level ranging from around 5.5 to 7.0. This makes it a mildly acidic beverage, similar to regular green tea.

To put it in perspective, the pH of water is neutral, around 7.0, while coffee and fruit juices often have lower pH values, indicating higher acidity.

Is Matcha acidic according to scientists?

Scientific studies and research have been conducted to analyze the pH levels of various teas, including matcha. These studies typically involve measuring the pH of tea infusions and comparing the results to the pH scale.

While specific research on matcha's acidity may vary, the consensus is that matcha falls within the mildly acidic range.


Is Matcha Acidic Compared to Coffee?

Matcha and coffee are often compared to one another when it comes to caffeine, health benefits and flavor so let’s do a quick comparison of the acidic, to determine is matcha acidic when compared to other popular beverages.

Acidity of Coffee

The pH of coffee is between 4.5 and 5, which makes it quite acidic, almost on a similar level to beer. As we mentioned before, matcha is only slightly acidic, and some matcha can be neutral like water.

What’s even more impressive is that matcha actually has an alkalizing effect on the body, so it works for restoring your pH balance.

Air Exposure

When matcha tea is exposed to air, it can undergo oxidation, which may lead to changes in its chemical composition. This oxidation process can cause a slight decrease in pH over time, making the tea slightly more acidic.


Moisture can also affect the pH of matcha tea. When matcha is exposed to moisture, it may absorb water, which can lead to hydrolysis of some compounds present in the tea. Hydrolysis can alter the pH of the tea, making it slightly more acidic.

Light Exposure

Exposure to light, especially direct sunlight, can degrade certain compounds in matcha tea. This degradation can lead to changes in the pH level of the tea.


Fluctuations in temperature during storage can impact the stability of the compounds in matcha tea. Extreme temperatures can accelerate chemical reactions that affect the pH of the tea.


Other Factors that affect the Acidity of Matcha

In addition to storage, there are a few other factors that can complicate the question of is matcha acidic. Let’s go through each one briefly. 

Growing Conditions

The products applied to the tea plants used to make matcha can have an impact on the final product. This means that the ph of the soil, the ph of the water and the ph of the fertilizer can all make matcha more or less acidic. This is something to keep in mind when you are wondering is matcha acidic.

Processing Methods

How the matcha is processed can also affect the pH. For example, if the tea leaves are steamed for a longer time, the pH will be raised slightly, making the matcha closer to neutral. 

Also, blending the tea leaves during the production will influence the pH. Some farmers make teas using multiple tea plant varieties grown on different plots of land, and this will impact the acidity of the finished product.


Of course this biggest factor that can influence the acidity of matcha is the ph of the water you use, as matcha tea is mostly water. Assuming you use perfectly neutral water, you can still influence the acidity of matcha by using a higher brewing temperature.

Using extremely hot water may increase the extraction of certain compounds, which can lead to a more acidic taste. On the other hand, using cooler water (around 160°F or 70°C) may result in a less acidic taste.

Is Matcha Acidic Even Though it is Alkalizing?

When people ask is matcha acidic, it’s important to point out that even though it is slightly acidic, matcha has an alkaline nature when metabolized in the body. 

This means that it can help balance the body's pH levels, promoting a more alkaline environment.

An alkaline state is believed to be beneficial for overall health, as it may support the body's natural detoxification processes and reduce the risk of certain health issues related to acidity, such as acid reflux and digestive discomfort.

Why is matcha acidic but alkalizing?

Catechins and amino acids found abundantly in matcha play a vital role in neutralizing acidity. Catechins are a group of antioxidants that have an alkalizing effect on the body when metabolized. 

One particular catechin in matcha, epigallocatechin gallate (EGCG), has been extensively studied for its potential health benefits, including its ability to counteract oxidative stress and inflammation.

Is Matcha Tea Acidic: Debunking Myths and Misconceptions

Several misconceptions have arisen around matcha's acidity, leading to concerns about its impact on health. Some myths suggest that matcha is excessively acidic and can harm tooth enamel or cause acid-related issues in the stomach.

However, scientific evidence shows that matcha's mildly acidic nature is not a cause for alarm. The pH level of matcha is within a safe range for consumption, and when consumed in moderation, it is unlikely to cause any negative effects on dental health or digestive system.


How to Reduce the Acidity of Matcha

Moderation is Key

As with any beverage, moderation is essential. Enjoying matcha in reasonable amounts as part of a balanced diet is safe for most individuals. Also, make sure not to drink too much matcha on an empty stomach

Pair with Alkaline Foods

Enhance the alkalizing effect of matcha by pairing it with alkaline-rich foods, such as leafy greens, fruits, and vegetables.

Is Matcha Acidic? The Final Verdict

In summary, matcha is mildly acidic in its raw form but has an alkalizing effect on the body when metabolized. 

The presence of catechins and amino acids in matcha plays a role in neutralizing acidity and contributing to potential health benefits. Debunking myths about matcha's acidity reveals that it can be safely enjoyed as part of a healthy diet.

Ultimately, incorporating matcha into one's lifestyle should be based on individual preferences and considerations. With its unique flavors, antioxidants, and alkalizing properties, moderate consumption of matcha can be a delightful addition to a well-balanced diet.
