Highly acidic beverages can contribute to digestive difficulties, such as heartburn and acid reflux. So which is more acidic, coffee or tea?
What Is Acidity?
Acids are sour and corrosive. They become more neutral when mixed with a base (alkaline). The pH scale describes chemicals ranging from extremely acidic (0), neutral (7.0), and extremely alkaline (14.0).
Coffee's Acidity
Coffee beans grown in very high altitudes and mineral-rich soil often produce more acidity. The acid content also depends on the type and length of bean roasting and brewing method. Coffee's pH averages about 5.0,
Tea's Acidity
Tea contains tannic acid, which becomes bitterer as the tea is steeped. Depending on the type, tea has a pH ranging from 4.0 to 6.0. Ginger tea and green tea are lowest in acidity.
Where to Find Low-Acid Products
Many coffee manufacturers, like Puroast and Hevla, offer low acid coffee. Yunnan tea has a low acid level, as do ginger and green teas. All these products are available at grocery stores and online.
How to Make Low Acid Coffee
Add cold water to ground coffee and let it sit for at least 12 hours. Then use the concentrate to make less acidic coffee.
How to Make Low Acid Tea
Select caffeine-free or low-caffeine tea. Brew only for a few minutes.
