Is apple juice an acidic drink?

Apple juice is a popular beverage, especially among children. But is it an acidic drink? In this article, we’ll examine the pH level of apple juice and compare it to other common beverages to determine just how acidic it is. We’ll also look at whether the acidity has any health effects, both positive and negative. Lastly, we’ll provide some tips on how to reduce the acidity of apple juice if desired.

The pH of Apple Juice

pH is a measure of acidity or alkalinity. The pH scale runs from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most alkaline or basic. Most fruits, including apples, contain organic acids that give them a pH below 7, meaning they are acidic.

Beverage pH Level
Lemon juice 2.0-2.6
Orange juice 3.3-4.2
Apple juice 3.4-4.0
Grapefruit juice 3.0-3.3
Black coffee 4.5-5.0
Milk 6.5-6.7
Pure water 7.0

The pH of apple juice ranges from 3.4 to 4.0, making it more acidic than orange juice but less so than lemon or grapefruit juice. So while apple juice is acidic, it is not as highly acidic as some other common beverages.

Acidity Comparison to Other Drinks

To better understand where apple juice falls on the pH scale, let’s compare its acidity level to some other popular beverages.

Beverage pH Level Acidity Description
Soda (cola) 2.5 Highly acidic
Lemonade 2.4 Highly acidic
Orange juice 3.5 Moderately acidic
Apple juice 3.5 Moderately acidic
Tomato juice 4.2 Mildly acidic
Milk 6.7 Neutral
Water 7.0 Neutral

As you can see, apple juice falls right in the middle, being more acidic than milk or water but less so than many other fruit juices and sodas. With a pH around 3.5, apple juice is moderately acidic.

Effects of Acidity on Health

Now that we’ve established apple juice as a moderately acidic beverage, what does that acidity mean for our health? Here are some potential effects of the acid in apple juice:

Positive Effects

  • Aids digestion – the acids may help break down food
  • Provides vitamin C – apple juice has antioxidant properties
  • Prevents kidney stones – citric acid prevents calcium kidney stones
  • Lowers cholesterol – animal studies show polyphenols may reduce cholesterol

Negative Effects

  • Tooth enamel erosion – acids can wear away tooth enamel over time
  • Irritation – may cause reflux, heartburn, or upset stomach if consumed excessively
  • Decreased calcium absorption – acids impair absorption of calcium in bones
  • Blood sugar spikes – juice lacks fiber and causes blood sugar spikes

The acidity makes apple juice a double-edged sword. While it provides some benefits, drinking too much could lead to dental issues or other problems. Moderation is key.

Tips to Reduce Acidity of Apple Juice

If you or your children drink a lot of apple juice but you’re concerned about the acidity, there are a few simple tricks to reduce its pH level:

  • Dilute with water – Add equal parts water to cut acidity in half.
  • Mix with milk – The proteins in milk neutralize acids.
  • Switch to whole apples – Gets fiber for slower digestion and absorption.
  • Rinse mouth after – Rinse mouth with plain water to wash away acids.
  • Use a straw – Bypass teeth to minimize enamel exposure.

Making these small tweaks when drinking apple juice can go a long way towards reducing tooth erosion and other side effects of acids. Be sure to monitor children’s juice intake and follow serving size recommendations.


Apple juice has a pH around 3.5, making it moderately acidic. While the acidity provides some health benefits, it can also harm teeth and potentially irritate the digestive system when consumed excessively. Diluting, mixing, or rinsing with water are simple ways to reduce the acidic impact of apple juice. Overall, apple juice is fine in moderation as part of a balanced diet. But its acidic nature is worth being aware of, especially for children’s dental health.
