3 oz jar of North Mountain Supply food grade calcium sulfate (gypsum), packaged in a plastic jar with a tamper evident, air tight seal for freshness.

North Mountain Supply food grade calcium sulfate (gypsum) in a 3 oz jar is a versatile mineral additive for brewers, home cooks and gardeners. Packaged in a plastic jar with a tamper evident, air tight seal, it is easy to measure, store and keep fresh between uses.
In brewing, calcium sulfate is widely used to adjust water chemistry, especially when working with soft or distilled water. By increasing calcium and sulfate levels it can:
Add hardness to brewing water
Help lower mash pH toward the desired range
Improve clarity and protein settling during the boil
Support better flavor profiles in certain beer styles
A common starting guideline is about 1 teaspoon of gypsum for 5 gallons of brewing water, but exact additions should be based on your water profile, recipe and target style.
Beyond brewing, this food grade calcium sulfate has several culinary and beverage uses:
Traditionally used for making tofu, where it acts as a coagulant
Helps control tartness and clarity in certain wines
Used as an ingredient in pickling and canning recipes where calcium support is desired
In the garden, gypsum is valued as a soil amendment that can:
Increase calcium and sulfur levels in soil
Help improve soil structure and water retention in some conditions
Be part of treatment strategies for blossom end rot when combined with good watering practices
Support production of mushroom spawn in specialized growing setups
Outside of food and garden uses, calcium sulfate is also employed in building and craft applications to make plasters, molds and casts, although those projects often use different grades and formats tailored to construction or art.
