Chalk (Calcium Carbonate) - 3.5 oz (99 g)

Chalk is not only good for writing on blackboards and sidewalks, but it can also make a huge difference in the quality of your brewing water. Typically used for beers that employ water that is too soft and has a low pH value, Chalk can enhance the enzymatic activity in a mash, increase its pH value, and accentuate the hop and malt flavour character in the final beer.

For best results, consult with your local water report and adjust the addition levels according to the target water profile and beer style you have in mind.
