Different beer styles will call for different levels of minerals to achieve the flavour profile we are targeting. By adjusting the amounts of specific minerals found in your brewing water, beer can be made to taste fuller bodied, sweeter, drier, more bitter, or even sour.
The following minerals found naturally in water are the ones we adjust in brewing:
The salts we use to adjust the mineral content of our water are as follows:
Guide line flavour profiles:
The five minerals that create the flavour profile we care about in brewing are Ca, Mg, Na, Cl, and SO4. Most other minerals and compounds and most definitely all contaminants should be close to zero if the water is to be used for brewing. Have your brewing water tested, or obtain the parameter values for your local water report.
Before we can calculate the amount of salts we need to add to hit our mineral targets, we need to know how much strike and sparge water we will be using.
We now have all the numbers we need to calculate the salt amounts required to hit our mineral targets. There are many tools available to perform these calculations. We like to use the free spreadsheet EZWaterCalculator as it’s one of the most intuitive and easy to use tools we have come across. Downloadable as well so you have something you’ll be able to use for life.
And it is as easy as that. Your water profile is complete!
