Understanding Tea's pH
Tea, like many beverages, falls somewhere on the pH scale, which measures acidity and alkalinity. A pH of 7 is neutral, anything below is acidic, and anything above is alkaline. The pH of your tea can be influenced by several factors, including the type of tea plant, its processing, and even brewing methods. The oxidation process, for instance, is a major factor: teas that undergo longer oxidation, like black tea, tend to be more acidic, while less oxidized varieties, like green and white tea, are more alkaline.
The Most Alkaline Teas
For those seeking a less acidic brew, herbal teas and certain varieties of true teas are your best bet. Minimally processed teas tend to retain a higher pH, often leaning towards neutral or alkaline. Herbal infusions, or tisanes, are naturally caffeine-free and gentler on the digestive system, though their pH can vary depending on the ingredients.
Green Tea
Green tea is one of the most alkaline true teas, with a pH often ranging from 7 to 10, depending on the variety and brew time. This minimal oxidation process helps preserve its naturally higher pH. Varieties like Kukicha, which is made from the stems and twigs of the tea plant, are particularly noted for their strong alkalizing properties. Sencha is another green tea known for its beneficial properties.
White Tea
Even less processed than green tea, white tea is made from the young buds and leaves of the Camellia sinensis plant, which are simply withered and dried. This minimal processing results in a brew with a high pH, ranging from approximately 6.9 to 9.7, making it a very safe and alkaline choice.
Chamomile Tea
A classic herbal infusion, chamomile is well-regarded for its calming effects and anti-inflammatory properties, making it an excellent choice for a soothing, low-acid beverage. It typically has a pH ranging from 6.8 to 7.5. This caffeine-free option is often recommended for those with acid reflux or sensitive stomachs.
Ginger Tea
Ginger tea is a popular remedy for digestive issues and is naturally alkaline, with a pH between 7.0 and 7.5. Its anti-inflammatory properties can help reduce irritation and aid digestion, although individuals with severe acid reflux should start with a small amount to see how their body reacts.
Licorice Root Tea
This herbal tea has been used for centuries to soothe digestive issues. Licorice root contains compounds that can increase the mucus coating on the esophageal lining, protecting it from stomach acid. It is often available in a deglycyrrhizinated (DGL) form, which is safer for long-term use.
Other Alkaline Herbal Teas
Several other herbs and plants make for naturally alkaline infusions, including:
- Rooibos: A reddish, naturally sweet, and caffeine-free herbal tea from South Africa, with a pH often between 5.5 and 7.
- Fennel Tea: Made from fennel seeds, this tea can help with digestion and reduce bloating.
- Dandelion Tea: Made from the root, dandelion tea supports liver function and can help with overall digestive health.
- Marshmallow Root and Slippery Elm: These herbs contain a gel-like substance called mucilage, which can coat and protect the lining of the esophagus and stomach from acid.
Comparison: Alkaline vs. Acidic Teas
To make an informed choice, it helps to compare the teas on both sides of the pH spectrum. The table below outlines some key differences.
| Feature | Alkaline Teas (e.g., Green, White, Chamomile) | Acidic Teas (e.g., Black, Citrus/Fruit Blends) |
|---|---|---|
| Processing | Minimally or non-oxidized; herbal infusions | Fully oxidized (Camellia sinensis); often blended with acidic fruits |
| Typical pH Range | Neutral to alkaline (7.0–10.0 for true teas; 6.0–7.5 for most herbals) | Mildly to highly acidic (4.9–5.5 for black; 2.0–4.0 for fruit blends) |
| Effect on Stomach | Soothing, gentle, and less likely to cause irritation | Can aggravate sensitive stomachs and acid reflux |
| Ingredients to Avoid | None with pure herbals; be wary of citrus blends | Lemon, hibiscus, rosehips, and other acidic fruit additives |
| Caffeine Content | Typically caffeine-free or very low caffeine (in true teas) | Higher caffeine content, which can trigger symptoms |
Brewing for Optimal Alkalinity
Even with a naturally alkaline tea, your brewing method can influence the final pH. To ensure the most alkaline result, consider these tips:
- Use alkaline water: Brewing with alkaline water can further increase the pH of your tea.
- Control steeping time: Longer steeping times can release more tannins and other acidic compounds, making the tea more acidic. Opt for shorter steep times, typically 2–5 minutes, for a milder, more alkaline brew.
- Use fresh leaves: High-quality loose leaf tea is often less processed and can produce a better-tasting, less acidic brew than lower-grade tea bags.
Conclusion: Finding the Right Alkaline Tea for You
For individuals seeking a gentler beverage, knowing which teas are more alkaline is a valuable tool. Opting for minimally processed true teas like green and white tea, or soothing herbal infusions like chamomile and ginger, can provide a flavorful and comfortable experience. By being mindful of ingredients, brewing methods, and potential additives, you can easily select a tea that is not only delicious but also supportive of your digestive well-being. Always listen to your body and consult a healthcare professional if you experience persistent acid reflux or discomfort from certain teas.

Frequently Asked Questions
What tea has the highest pH level?
The highest pH levels are typically found in minimally oxidized true teas like certain green and white teas, with some varieties having pH values reaching up to 10.
Is green tea acidic or alkaline?
Green tea is generally more alkaline than acidic. Unlike black tea, which is fully oxidized, green tea is only minimally processed, leaving it with a pH that can be neutral or slightly alkaline, often ranging from 7 to 10.
Is ginger tea good for acid reflux?
Yes, ginger tea is often recommended for acid reflux due to its anti-inflammatory properties, which can help soothe an upset stomach. However, as ginger can be a mild irritant in large quantities, it's best to consume it in moderation.
What ingredients should I avoid in tea for acid reflux?
For sensitive stomachs and acid reflux, you should avoid teas containing acidic fruits like lemon, hibiscus, rosehips, and citrus peels. Black tea, due to its higher acidity and caffeine, can also be problematic for some individuals.
Can I make my tea more alkaline?
Yes, you can make your tea more alkaline by using a shorter steeping time, brewing with alkaline water, or adding a dash of milk or a neutral sweetener like honey.
Is peppermint tea good for a sensitive stomach?
While some find peppermint soothing for digestion, it can actually relax the lower esophageal sphincter in some individuals, which can worsen acid reflux symptoms. It's best to test your personal tolerance with this one.
How does processing affect tea's pH?
The level of oxidation during processing is the primary factor. Fully oxidized teas like black tea have a lower, more acidic pH, while unoxidized or minimally oxidized teas like green and white tea have a higher, more alkaline pH.
