We wanted to brew better beer. So we invented the pH scale.

Is brewing probably the best beer in the world an art....

...or science?

We believe it’s a bit of both.

We proved this in 1909 when, in our pursuit of making better beer, we invented the pH scale – now a global scientific standard used to measure the acidity and alkalinity of any given substance.

 

What's just as good?

By giving us a way of measuring the perfect acidity level of water used for brewing, the pH scale allows us to brew consistently great tasting beer.

With the invention of the pH scale, we could ensure consistently great tasting beer every time. And of course, we shared our invention with the world.

We didn't do it for the publicity. After all, it was 1909. We simply believe that just like great beer, great ideas are for sharing.

A colourful breakthrough.

The bright and simple pH scale is now the standard, and a useful device in many fields - including education, medicine, food science, and, of course, brewing.

5 ways the pH scale
changed the world

What exactly is measuring acidity and alkalinity of a given substance good for? As it turns out: Quite a lot. Here are 5 ways the pH scale changed the modern world.

 

Drinking water

Neither acidic or basic but completely neutral, classic tap water has a pH value of approximately 7. The pH scale is used to make sure that this is always the case.

Consistently great tasting beer

The pH scale is used to measure and ensure consistently great tasting beer, every time.

Optimal growing conditions for crops

In agriculture, the pH scale is used to measure and adjust soil to optimise growing conditions for crops such as barley, corn and grass.

Everyday medicine

The pH scale is used as a key component in various types of medicine - specifically to determine what's needed in order for a given drug to work effectively

Large-scale manufacturing

In large-scale manufacturing, the pH scale is used to ensure that ships and aeroplanes are resistant to corrosion by sea-water and air.
