To make black tea less acidic, you can add a pinch of baking soda to neutralize acidity, brew with cooler water, or mix in milk or cream, which can help balance the flavor and reduce the perception of acidity.
Black tea lovers with sensitive stomachs often struggle with its natural acidity. While black tea typically has a pH of 6.37 (less acidic than coffee), some brewing methods and additives can make it gentler on digestion. Here’s how to enjoy your favorite brew without the acid reflux.
Why Black Tea Causes Acidity
The tannins in black tea stimulate stomach acid production. Oxidation during processing also increases acidity compared to green or white teas. Those with GERD or acid reflux may experience discomfort, especially when drinking strong black tea on an empty stomach.
pH Levels of Common Teas
| Tea Type | pH Level |
|---|---|
| Black Tea | 6.37 |
| Green Tea | 7-10 |
| Herbal Tea | 6-7 |
| Coffee | 5.35 |
7 Ways to Reduce Black Tea Acidity
1. Add Milk or Cream
Dairy neutralizes tannic acids. Whole milk works best, but almond or oat milk are great alternatives. The proteins bind to tannins, reducing their irritant effects. This method is particularly effective for those with gastritis.
2. Use Cold Brew Method
Cold brewing extracts fewer tannins over 6-12 hours. This results in a smoother, 67% less acidic tea according to Journal of Food Science studies.
3. Shorten Steeping Time
Limit steeping to 2-3 minutes instead of 5. Longer steeping releases more tannins. Set a timer for precision.
4. Add Baking Soda
A pinch (1/8 tsp per cup) alkalizes the tea without affecting flavor. Stir completely to dissolve.
5. Choose Low-Acid Varieties
Darjeeling and Chinese Keemun teas are naturally lower in acidity than Assam or Ceylon. Aged pu-erh has even less acidity.
6. Use Filtered Water
Hard water increases acidity. Soft or filtered water (pH 7) creates a more neutral brew. Test your water with pH strips.
7. Pair With Food
Eating neutral foods like toast or crackers buffers stomach acid. Avoid citrus fruits which compound acidity.
Teas to Avoid With Acid Reflux
While these methods help with black tea, some may prefer alternatives. Highly acidic options include:
- Fruit-flavored black teas
- Earl Grey (bergamot increases acidity)
- Instant teas
- Over-steeped tea
For sensitive individuals, chamomile tea makes an excellent low-acid alternative with anti-inflammatory benefits.
Expert Tips for Tea Drinkers
Tea researcher Dr. Li Wei recommends:
- Wait 30 minutes after eating to drink tea
- Maintain water temperature at 195°F (90°C)
- Use 1 tsp loose leaf per 8oz water
- Rinse leaves briefly with warm water first
Those with severe GERD may need to limit black tea intake to 1-2 cups daily and monitor individual tolerance. The right preparation makes all the difference in enjoying this antioxidant-rich beverage comfortably.
