What is pH?

pH is the measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a larger concentration of hydrogen ions than water are acid and have a pH value of less than 7. Liquids with a lower concentration of hydrogen ions, on the other hand, are base and have a pH value higher than 7. The pH scale runs from 1 to 14.

What effect does pH have on brewing?

The correct pH will help carry flavour and ensure optimal enzymatic activity, you need the correct temperatures for enzyme activity but it's also equally important to have the correct pH. Testing your pH levels will help you make better quality beer. Our tip for understanding pH is to take regular readings at different stages through the brewing process so you can really understand what's happening.

The maintenance of a pH meter

The pH meter is a precision instrument. Proper use and appropriate maintenance are important to enjoy your pH meter for a long time. Here are some considerations:

- Before the first measurement, the pH meter should be calibrated with the buffer solutions. If the pH meter can only be calibrated at one point, use the buffer solution that is closest to your normal measurements.

- When calibrating be careful that no contamination of the buffer solution occurs. Therefore never insert the electrode directly into the bottle. Instead, pour a small amount into a separate cup, and use this for your measurements. . After calibration throw away the used cups, do not pour the liquid back into the bottle!
