Kombucha is popular for its alleged health benefits. It contains billions of probiotics (living bacteria), which is the main reason for its popularity.

Still, many people are unsure whether Kombucha is good for acid reflux. So, here is a question about its nature, “is Kombucha acidic?”

Kombucha is acidic which has a pH range less than 4.6, has a tart, tangy, and slightly sour taste. It is a fermented drink and the duration of fermentation determines the acidity of Kombucha. It is nearly as acidic as pop and energy drinks.

The nature of Kombucha is still debatable. So, let’s explore the benefits of the heart.

Kombucha Acidic Or Alkaline?

Kombucha is considered to be highly acidic. The alcohol and acetic acid are synthesized by SCOBY (symbiotic culture of bacteria and yeast), and these products are converted into acidity, giving the Kombucha a tart taste.

To enhance the taste, some companies add ginger, grapes, strawberries, lemon, cranberries, and Synergy’s Maqui Berry Mint, a mojito-inspired drink.

Is Kombucha Tea Alkaline Or Acidic?

The acidic nature of Kombucha is indicated by its pH being less than the neutral range (below 7). When it is consumed, the body becomes acidic, and its normal functions are disrupted.

Is Raw Kombucha Acidic?

Kombucha’s pH is less than 4.6, and it varies depending on the degree of fermentation. The dominant type of bacteria in Kombucha, Acetobacter, Gluconacetobacter, produces acetic acid, one of the most healthy acids and a clue to Kombucha’s low pH. Therefore, foods with a pH of 4.6 or lower have been deemed safe for sale without additional preservatives.


Kombucha is a fermented tea made from sugar, yeast, and black tea that has been fermented for weeks or more. During that time, bacteria and acids, as well as a trace of alcohol, form in the drink. As a result, it contains lactic acid bacteria and a healthy dose of B vitamins.

These bacteria and acids combine to form a film on the liquid’s surface known as SCOBY (symbiotic colony of bacteria and yeast).
