When discussing beverages, acidity refers to their pH level, which measures how acidic or alkaline they are. Tea, one of the most consumed drinks worldwide, sparks curiosity about its acidity and how it affects health.
This is particularly relevant for individuals with sensitive stomachs or acid reflux issues. The pH levels in tea vary widely, influenced by the type of tea and brewing process. Understanding tea’s acidity is essential for making informed choices about what you drink.
The Science Behind Tea’s Acidity
What Makes Tea Acidic?
The pH scale ranges from 0 to 14, with values below 7 being acidic and above 7 being alkaline. Most teas fall between 5 and 7 on the pH scale, making them mildly acidic to neutral.
Tea contains natural compounds like tannins and polyphenols, which contribute to its acidity. These compounds give tea its unique flavor and health benefits but can also affect its pH. For example, black tea tends to have more tannins, making it slightly more acidic than green tea.
The brewing process also plays a role. Longer brewing times and higher temperatures can extract more acidic compounds, increasing the tea’s acidity. Additionally, additives like lemon or sugar can further alter the pH, making it more acidic.
Comparing Tea to Other Beverages
Is Tea More Acidic Than Coffee?
When comparing tea and coffee, coffee is often perceived as the more acidic option. Coffee typically has a pH range of 4.5 to 5.5, while most teas range from 5 to 7, depending on the type.
However, coffee’s acidity feels stronger due to its higher concentration of chlorogenic acids, which can irritate the stomach. On the other hand, tea has a more balanced acidity, making it gentler on digestion.
For example:
- Green tea has a pH of about 6 to 7.
- Black tea ranges from 5 to 6.
- Herbal teas, like chamomile, are often closer to neutral.
This makes tea a preferred option for those who are acidity-sensitive.
Types of Tea and Their Acidity Levels
Exploring Different Teas: Which Are Acidic and Which Are Alkaline?

Alkaline teas have pH levels above 7. Examples include rooibos and some blends of herbal teas. These teas not only help balance your body’s pH but are also gentle on the digestive system.
Is Tea with Milk Acidic?
Adding milk to tea can alter its acidity. When milk is added, the pH of tea generally increases, making it less acidic. For instance, black tea has a pH of around 5 to 6, but when milk is added, it can shift closer to neutral. This is because milk contains calcium and proteins, which help buffer acidity.
For individuals with acid reflux, tea with milk can be a gentler option. The milk helps coat the stomach lining, potentially reducing irritation caused by acidic beverages. However, full-fat milk may sometimes aggravate symptoms in those sensitive to fatty foods. In such cases, low-fat or plant-based milk, like almond or oat milk, may be better alternatives.
Tea and Acid Reflux
Is Tea Acidic for Acid Reflux?
Tea’s acidity can affect individuals with acid reflux differently. For some, acidic teas like black or citrus-flavored teas might worsen symptoms. The caffeine in tea can also relax the lower esophageal sphincter, allowing stomach acid to rise into the esophagus.
To minimize discomfort:
- Opt for low-acid teas like chamomile, rooibos, or peppermint.
- Avoid adding lemon or sugar, as they can increase acidity.
- Brew tea lightly to extract fewer acidic compounds.
Drinking tea with food can also help buffer its acidity. Each individual reacts differently, so monitoring symptoms after drinking tea is key.
