The Science of Acidity: Understanding the pH Scale
To accurately compare English breakfast tea and coffee, one must first understand the pH scale. This scale is a measure of how acidic or alkaline a substance is, ranging from 0 to 14. A pH of 7 is neutral, like pure water. Any value below 7 is considered acidic, with lower numbers indicating higher acidity, while values above 7 are alkaline. Both tea and coffee are naturally acidic beverages, but their specific pH levels and acid compositions differ.
English Breakfast Tea vs. Coffee Acidity: A Direct Comparison
English breakfast is a type of black tea made from oxidized Camellia sinensis leaves. Coffee is made from roasted beans. Most black teas, including English breakfast, have a pH level ranging from 4.9 to 5.5. Typical brewed coffee has a pH between 4.85 and 5.4. Coffee is generally slightly more acidic, a difference that can matter for those with acid reflux or sensitive stomachs.
Comparison of English Breakfast Tea and Coffee
| Feature | English Breakfast Tea | Coffee |
|---|---|---|
| Typical pH Range | 4.9 - 5.5 | 4.85 - 5.4 |
| General Acidity | Mildly acidic | Moderately acidic |
| Primary Acids | Tannic acid, gallic acid, oxalic acid | Chlorogenic acid, quinic acid, citric acid |
| Effect on Stomach | Generally gentler | More likely to cause discomfort for some |
Factors That Influence Your Cup's Acidity
Brewing methods and additives significantly affect a beverage's final acidity. Longer brewing time for tea extracts more tannins, increasing bitterness and lowering pH. Hotter water also extracts more acidic compounds. Cold brewing results in a less acidic drink. Adding milk, which is nearly neutral, helps buffer acidity. Lemon increases acidity, while sugar has a slight effect. For coffee, lighter roasts are more acidic, and darker roasts less so. Green tea is typically less acidic than black tea.
Health Considerations for Acid-Sensitive Individuals
Individuals with acid reflux (GERD) or sensitive stomachs should be mindful of acidic beverages. The combination of acidity and caffeine can trigger symptoms. L-theanine in black tea may help balance caffeine's effects.
Tips for Reducing Acidity in Your Brew
To reduce acidity:
- Shorten Brewing Time: Steep English breakfast tea for 1-2 minutes.
- Add Milk: Milk or dairy alternatives neutralize acidity.
- Try Cold Brew: Cold brewing significantly lowers acidity in tea and coffee.
- Switch Teas: Green or herbal teas are often less acidic than black tea.
- Drink with Food: Consuming acidic beverages with a meal helps buffer the acid.
Conclusion
English breakfast tea is generally less acidic than coffee, though both are acidic. The difference is often small but can be important for sensitive individuals. Adjusting brewing and additives can control acidity and allow enjoyment of these beverages without discomfort.

Frequently Asked Questions
Q: What causes the acidity in tea? A: Acidity in tea primarily comes from tannins and other organic compounds extracted during brewing.
Q: Which is less acidic, green tea or English breakfast tea? A: Green tea is typically less acidic than English breakfast tea due to less oxidation.
Q: Does adding milk reduce the acidity of English breakfast tea? A: Yes, adding milk is effective in reducing acidity. Milk is nearly neutral and helps buffer the tea's tannins.
Q: Can drinking acidic beverages damage tooth enamel? A: Yes, frequent consumption of highly acidic drinks can erode enamel. The risk is lower with moderate intake of mildly acidic drinks like tea and coffee.
Q: Is it okay to drink English breakfast tea on an empty stomach? A: For some sensitive individuals, it can trigger acid reflux. Drinking it with food can help.
Q: Is cold brew English breakfast tea less acidic? A: Yes, cold brewing results in significantly lower acidity compared to hot brewing.
Q: How does the roast of coffee affect its acidity? A: Lighter roasts are generally more acidic, while darker roasts have a higher pH and are less acidic.
Key Takeaways
- English Breakfast vs. Coffee Acidity: English breakfast tea is generally less acidic than coffee, though both are mildly acidic.
- Influencing Factors: Brew time, temperature, and additives like milk affect acidity.
- Brewing for Less Acidity: Shorter steep time for tea or cold brewing for both reduce acidity.
- Buffering with Milk: Adding milk or alternatives neutralizes acidity, making tea gentler.
- Sensitive Stomach Options: Tea is often more tolerable than coffee for those with sensitivity.
- Cold Brew is Milder: Cold brewing creates a less acidic version of both beverages.
