pH of Drinks

Written by: Oli Baise
Last updated: April 17, 2023

I bought a pH tester and tested the acidity and alkalinity of common drinks. This includes various types of drinking water, alcoholic drinks, soft drinks, fruit juices and vitamin waters.

Key Findings

  • Still, sugar free flavored waters and vitamin waters tended to be more acidic than fizzy drinks.
  • Sainsburys Strawberry and Kiwi flavoured water was the most acidic drink tested with a pH of 2.8. This is the same as malt vinegar.
  • Sugar free fruit drinks and energy drinks (including squash) are just as acidic as fizzy drinks.

Here is a searchable table of all the tested drinks along with their pH and level of erosiveness:

What are the Health Affects of Drinking Too Many Acidic Drinks?

According to the NHS and The Oral Health Foundation the two main health problems associated with consuming a lot of acidic food and drinks are:

  • Oral health problems: sensitive teeth and tooth decay due to acid erosion.
  • Digestive problems: acid reflux, heartburn and indigestion.

The vast majority of this data was created myself.

I bought a Bluelab pH testing pen (this is considered the most accurate Ph tester on the market) and tested all the products myself following the pen’s manufacturer instructions.
