Removing Chlorine From Brewing Water using Campden
Using Campden tablets (Potassium metabisulfite) is a great way to ensure your brewing water is free of chlorine and chloramine.
These two compounds can be detrimental to the flavor of your brew, so it’s important to remove them before you start brewing.
Potassium metabisulfite, also known as potassium pyrosulfite, is a chemical compound with the formula K2S2O5.
When it is added to water that contains chlorine, the potassium metabisulfite will react with the chlorine to form potassium chloride and sulfur dioxide gas (will smell like farts…).
The reaction can be represented by the following equation:
2K2S2O5 + 2Cl2 -> 4KCl + 2SO2 + O2
In this equation, the potassium metabisulfite is represented by K2S2O5, and the chlorine is represented by Cl2. The reaction produces potassium chloride (KCl), sulfur dioxide (SO2), and oxygen gas (O2).
KCL is a harmless salt, just like table salt (NaCl) and effectively has no chlorine taste in water.
As a homebrewer, you can use potassium metabisulfite to remove chlorine from water. This is important because chlorine can have a negative impact on the flavor of your beer.
It’s also recommended that you add Campden as a precautionary measure if you aren’t sure whether or not there are chlorine or chloramine present in your tap water supply already.
To find out more information about what might be in your local tap water, contact the town or city supplier for details on their specific composition levels.
Campden tablets offer an easy way to keep unwanted contaminants out of our beer while still allowing us to enjoy delicious home brewed beverages without worry!
