Each type of beer needs a specific water composition and PH. Accurate adjustment of these is essential to produce a truly high quality beer. Each enzyme and yeast also has an optimum PH at which it works effectively. Adjusting the pH improves yield and makes yeast ester production more predictable.
Otherwise, your local water company can give you information on the exact composition of your tap water.
Our recipe kits do not include the tools needed to adjust the pH.
The Ph adjustment procedure:
- After mashing, stir the mash for about 5 minutes and then dip one of the pieces of litmus paper into the mash
- The degree of discoloration indicates the Ph. The aim is to get a Ph between 5.1 and 5.4.
- Using a pipette, measure out 2ml of lactic acid if you are still within the desired pH.
- Mix the lactic acid in the mash and measure again.
- If the pH is not yet correct, another dose of lactic acid is added as the pH approaches the correct pH.
