Dandelion tea is mildly acidic to near neutral, with a pH that generally falls between 5.5 and 6.5 depending on how it’s prepared. That puts it on the less acidic end of the spectrum compared to most popular beverages, and well below the acidity of coffee or black tea.
Where Dandelion Tea Falls on the pH Scale
The pH scale runs from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral. Pure water sits right at 7. Most brewed teas and coffees land somewhere in the mildly acidic range between 4 and 7. Coffee typically has a pH around 5.35, and black tea ranges from about 4.9 to 5.5. Green tea sits higher, closer to neutral or even slightly alkaline at pH 7 to 10.
Dandelion tea, whether made from the root or the leaves, tends to land in the 5.5 to 6.5 range. That makes it noticeably less acidic than a cup of coffee and gentler than most black teas. It’s closer in acidity to plain water than to your morning espresso. If you’re comparing common beverages, dandelion tea is one of the milder options you can choose.
What Makes It Slightly Acidic
Dandelion plants contain over 50 bioactive compounds, and among the most prominent are phenolic acids. Three in particular, chlorogenic acid, caffeic acid, and chicoric acid, are considered the key active constituents in dandelion. These are the same types of compounds found in coffee and many fruits, and they’re largely responsible for the mild tang you might notice when sipping dandelion tea.
These organic acids aren’t present in high enough concentrations to make the tea strongly acidic. They do, however, contribute to both the flavor and the health properties dandelion tea is known for. Phenolic acids function as antioxidants and have anti-inflammatory effects in the body, so their presence is generally considered a benefit rather than a drawback. The slight acidity they create in your cup is a natural byproduct of those same compounds.
How Steeping Time Changes the Acidity
The longer you steep dandelion tea, the more compounds dissolve into the water, and that includes organic acids. Research examining dandelion tea brewed for periods ranging from 1 hour to 36 hours found that the concentration of organic acids, phenolic compounds, and other metabolites increased significantly over time. The most dramatic changes happened after about 12 hours of steeping, the point where overnight brewing begins.
For a standard 5 to 10 minute steep, you’re extracting a moderate amount of these acids, keeping the tea mild. If you cold-brew dandelion tea overnight or let it sit for extended periods, expect a slightly more acidic and stronger-tasting result. The tea won’t become dramatically sour, but the shift is measurable. A short steep with hot water gives you the gentlest cup.
Dandelion Tea and Acid Reflux
Because dandelion tea sits close to neutral on the pH scale, many people with acid sensitivity find it easier to tolerate than coffee or traditional teas. It’s a common swap for people looking to reduce the acidity in their daily routine without giving up a warm, slightly bitter beverage.
That said, dandelion tea isn’t universally gentle on every stomach. It can cause stomach discomfort, diarrhea, or heartburn in some people, according to WebMD. The heartburn risk isn’t necessarily about the tea’s pH level. Dandelion stimulates bile production and digestive activity, which can sometimes trigger reflux symptoms even when the beverage itself isn’t very acidic. If you have GERD or frequent heartburn, it’s worth starting with a small amount to see how your body responds rather than assuming it will be completely neutral for your digestion.
Acidic in the Cup vs. Acidic in the Body
There’s an important distinction between how a food or drink measures on a pH strip and how your body processes it. Some beverages that are mildly acidic before you drink them have an alkalizing effect once metabolized. Dandelion tea is often placed in this category by practitioners of alkaline diets, because the minerals it contains (potassium, calcium, magnesium) leave an alkaline residue after digestion.
Your body tightly regulates blood pH regardless of what you eat or drink, so the practical impact of any single beverage on your overall acid-base balance is minimal. But if you’re choosing dandelion tea specifically because you want a low-acid alternative to coffee, the numbers support that choice. It’s meaningfully less acidic in the cup, less likely to irritate sensitive tissue in the esophagus, and provides a bitter, earthy flavor profile that many coffee drinkers find satisfying as a substitute.
