The combination is pretty weird! Black tea, yeast, and sugar, and you got kombucha.

Kombucha lovers say this fermented tea is great for boosting energy, helping in digestion, and removing toxins from your body. But others say they have issues with the versatile taste-sometimes sweet or sometimes tangy.

You must be wondering about the diversity. And trying to figure out if kombucha is acidic or not?

Kombucha is acidic with the pH range between 2.5 to 4.2. When you ferment the kombucha tea, it produces less than 1% acetic acid which has a pH level of 3.0-3.5. This acid is responsible for the tangy nature of kombucha. Surprisingly,  moderate amount kombucha is good for reducing acid reflux too.

However, the actual pH level is dependent on the tea types, tea-sugar-yeast ratio, brew time, room temperature, and the length of fermentation.

Keep reading to learn more about the acidic nature of kombucha and its relationship with acid reflux. 

Kombucha – Acidic Or Alkaline? 

In one line, kombucha is acidic, not alkaline. Let me explain why!

Black tea, green tea, white tea, or oolong tea are used for making kombucha. However, black tea for its oxidized leaves nature is mostly preferable for making a perfect kombucha.

And the pH of black tea is 4.9-5.5 which is a good range to grow yeast perfectly. 

With time, the yeast of SCOBY (symbiotic culture of bacteria and yeast) starts eating the sugar content of the kombucha. That results in producing ethanol and it gradually turns acidic.

What about green tea or white tea kombucha? Well, they are neutral or basic, but with the fermenting process over time, the alkaline nature will vanish and turn into acidic for the yeast. 

pH of Kombucha

The pH of kombucha is directly related to the fermentation time. However, tea types and ratios also take part in the pH level of kombucha. 

And the pH value defines whether kombucha will taste sweet or tart. The pH like 3.5 ensures it will taste sweet. The lower pH like 2.5 makes the kombucha tart.

3 Ways: How To Raise The pH Of Kombucha? 

When you ferment kombucha, acetic and gluconic acid start producing by the fermenting  bacteria. That results in a lower pH level and makes the taste too tart.

Also, lower pH means the kombucha is highly acidic which is not good for you especially if you are struggling with acid reflux. 

Besides, when the taste is too tart, you may want to make it a little sweet. To make kombucha sweet, you have to increase the pH level. Here 3 ways to increase the pH of Kombucha – 

1. Less Ferment Time 

In general, the fermenting process takes from 7 days to 30 days. The more you ferment, the kombucha will be more acidic and vice versa. To make it less acidic, you can brew after the first fermentation which may take 6 to 10 days. 

2. Keep It in Room Temperature 

Kombucha brewing temperature affects the pH value directly. More than 85°F speeds up the culturing, which will result in lower pH.

To increase the pH level, you should keep the kombucha vessel at room temperature in between 68-78°F.

3. Maintain The Tea Leaf Ratio

Using more tea leaves can cause lower pH for the tea leaves’ oxidation nature over time. For each one-gallon batch, keep the ratio 6:1 for the tea leaves.

You can use 6 teaspoons of loose tea or 6 tea bags for each batch. So, keep the ratio perfect to get a higher pH kombucha. 

How Acidic Is Kombucha For The Body? 

Kombucha is acidic, but after drinking, it alkalizes the body. It’s because when you make kombucha using black or green tea, there will be several essential minerals such as manganese, potassium, copper, iron, fluid iron, etc.

The pH of our blood is 7.4 regarded as neutral. When these minerals of kombucha enter our bloodstream, that creates an alkalizing effect and results in a neutral state of our body.

Who Should Not Drink Kombucha? Are You in the 4 Categories?

Kombucha is considered safe and healthy to promote a healthy and smooth digestive system, boost energy and remove body toxins.

However, you are prohibited to drink kombucha under the following health conditions-

1. People With A Weak Immune System 

As bacteria and yeast take an active part in kombucha, that may cause infection for people with weak immune systems. 

2. Diabetics Patient

Kombucha contains a good amount of sugar. So it may increase blood sugar levels. Also, alcohol production during fermentation can cause complications for diabetic patients. 

3. Pregnant, Breastfeeding Women And Kids

For the alcohol and caffeine, pregnant and breastfeeding women should avoid kombucha. Similarly, the bacteria and yeast might be harmful to the developing baby.

Additionally, kids should not drink kombucha. The carbonate effect of kombucha will cause stomach upset.

4. People With Stomach Ulcers 

If you have stomach ulcers, kombucha may make it worse. The bacteria and acidic nature of kombucha can potentially aggravate stomach ulcers.

Is Kombucha Good For Acid Reflux? 

Acid reflux occurs when you eat or drink high acidic or high-fat content food and drinks. if you have a lower esophageal sphincter (LES), your stomach content leaks up back. That causes acid reflux.

Now the question is what about kombucha? Is it good for acid reflux or promotes acid reflux? 

The nature of kombucha is acidic, so you may think it’s not good for acid reflux. But the truth is kombucha is good for people who are suffering from acid reflux. 

Kombucha contains lactic acid which has probiotic properties. That can kill harmful bacteria as well as promote smooth digestion. So far, lactic acid is beneficial to reduce the chances of acid reflux.

The tea drink  is a great source of vitamin B. vitamin B can improve your gut health by controlling the production of stomach acid.

Several essential minerals of kombucha neutralize the acidic properties and make it alkalizing for your body. 

For these activities, kombucha is good for acid reflux. However, you should be concerned about your daily intake. You can drink around 4 ounces per day to avoid health complications. Also, avoid adding high sugar content to it to get the best result.

Is Kombucha Bad For Acid Reflux?

Drinking too much kombucha causes acid reflux. The recommended level is 4 ounces per day for 1 to 3 times.

However, kombucha will be bad for acid reflux under certain health conditions.

First of all, if you already have the symptoms of acid reflux, drinking too much kombucha may make it worse.

Kombucha contains a decent amount of caffeine and alcohol. Both can increase the acid production in your stomach and irritate your digestion which causes heartburn too. 

A lengthy fermentation process makes kombucha carbonated. And the carbonated nature feels your stomach fuller and pressurizes your lower esophageal sphincter. As a result, the acid flow starts moving back into the esophagus which leads to acid reflux directly.

In addition, the acetic acid of kombucha may also be responsible for acid reflux or GERD by disturbing your regular digestive system. 

Various Forms Of Kombucha And Its Acidity 

In the USA, around 14. 1 percent of adults drink kombucha in various forms such as kombucha tea, raw or hard kombucha for several purposes. The pH level and acidity are also different for each type. 

Is Kombucha Tea Alkaline Or Acidic?

Kombucha tea is acidic with a pH range of 2.5 to 3.5. However, using tea bags instead of tea leaves makes kombucha tea more acidic for rapid oxidation.

The type of tea affects the acidity of kombucha. If you use pure black tea, it will make kombucha too acidic as black teas are already acidic in nature.

pH wise oolong tea kombucha will be almost the same as the black tea version. Though green tea and white tea kombucha seem alkaline for their higher pH values. But during the fermentation process, the basic nature will be removed. 

Whether you use either green or white tea, the resulting kombucha tea will be acidic with a pH below 4.6. However, adding fruits or herbs can reduce the acidity of kombucha tea.

Is Hard Kombucha Acidic?

Hard kombucha is more acidic than kombucha tea. It’s the boozier version of the regular or raw kombucha. As hard kombucha fermented at 28°C/82.4°F or higher for 5 to 14 days, it will taste tangy and slightly vinegary.

Warm temperatures and lengthy fermentation, increases the ABV (alcohol by volume) and decreases the pH level to around 2.5.

Is Raw Kombucha Acidic? 

Raw kombucha is not pasteurized though it’s acidic with a pH of less than 4.6. Mostly, the pH level of raw kombucha is 2.5-3.5. During the fermentation period, the yeast starts feeding the sugar content and creates a suitable environment to grow gradually. This process enhances the pH level of the raw kombucha drink.

Fun fact: Do you know when and where the kombucha tea originated? In 220 BC, kombucha originated in China. Then it reaches Russia, USA, Germany and all over the world.
