There are a few ways to lower the pH of your brewing water:
- Add acid: You can add an acid, such as lactic acid or phosphoric acid, to your brewing water to lower its pH. The amount of acid you need to add will depend on the starting pH of your water and the desired pH for your beer.
- Use acidulated malt: Acidulated malt is malt that has been treated with lactic acid during the malting process. Adding acidulated malt to your mash can lower the pH of your brewing water.
- Dilute with distilled or RO water: If your brewing water has a high pH, you can dilute it with distilled or reverse osmosis (RO) water to lower the pH. This is especially useful if your tap water has a high pH or high mineral content.
- Use a water treatment agent: There are several water treatment agents, such as gypsum or calcium chloride, that can be used to adjust the pH of your brewing water. These agents are typically used to adjust the mineral content of the water but can also affect the pH.
It’s important to note that pH can have a significant impact on the flavour and character of your beer, so it’s worth taking the time to adjust your brewing water to achieve the desired pH for your specific beer style.
