This 500g pouch enhances water quality, adjusts pH levels, and promotes mycelium growth while preventing contamination, making it an essential ingredient for both brewers and mushroom enthusiasts. ## Description Product description Super Fine Powder - Food Grade Homebrewing - Water Treatment In brewing it is perhaps best known as the main mineral in the well water of Burton Upon Trent, England, and is widely attributed to be the essential component of the water for pale ale and India pale ale brewing; as such it is the main ingredient in the Burtonizing salts for brewing water treatment. It is added by dissolving the gypsum in the mashing and sparging water or directly as a powder into the grist or mash vessels at mashing. Gypsum’s positive effects are to reduce wort pH, improve malt extraction efficiency through enhanced amylolytic activity, give a buffering capacity to the wort, balance the hop flavor for highly hopped beers, improve wort clarity, and remove phosphates and proteins in the wort trub. Mushroom - PH Buffer The main reason is to add calcium carbonate and sulfur, which helps to stabilize PH levels to near neutral so it acts as a PH buffer as well as adding minerals which are vital for fruiting. Powdered gypsum is used to increase the PH in mushroom growing substrates such as grain, sawdust, coffee grounds and straw. It is also a yield enhancer as it supplies minerals and trace elements to the mycelium Various Weights - 250g - 500g - 1kg Directions To use, dissolve the gypsum in the mashing and sparging water or directly add as a powder into the grist or mash vessels at mashing for brewing. For mushroom cultivation, use powdered gypsum to increase the pH in mushroom growing substrates such as grain, sawdust, coffee grounds, and straw. It is also a yield enhancer as it supplies minerals and trace elements to the mycelium. Safety Warning May cause irritation to eyes and skin. Avoid contact with skin and eyes.

Review: Quality - Great product Review: Great product - I use this for mushroom growing and it is great had no problems at all ## Features - Super Fine E516 - Food Grade Gyspum (Calcium Sulphate Powder) In a Food Grade Resealable Pouch With Tamper Proof Seal - Water Modification - Gypsum is commonly used in homebrewing to modify the water profile. It enhances the calcium content in brewing water, which is crucial for various chemical reactions during mashing. - PH Adjustment - It helps in adjusting the pH of the brewing water. Gypsum is often employed to lower the pH of water that is too alkaline, creating a more suitable environment for enzymatic activities during mashing. - Buffering Capacity - Gypsum acts as a buffer, helping to stabilize the pH of the substrate in mushroom cultivation. This is crucial for maintaining optimal conditions for mycelium growth. - Mushroom Cultivation - Gypsum is widely used in mushroom cultivation, especially for species like oyster mushrooms. It provides a source of calcium and sulfur, promoting mycelium growth and overall mushroom development. - Prevents Contamination: The addition of gypsum in mushroom substrates can help prevent contamination by certain competing organisms. It creates an environment that is more favorable for the growth of desired mushroom species. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097374VQ3 | | Brand | Hugster | | Brand Name | Hugster | | Customer Reviews | 4.6 out of 5 stars 223 Reviews | | Item Form | Powder | | Item Weight | 500 Grams | | Item form | Powder | | Item weight | 500 Grams | | Manufacturer | Hugster | | Number of Items | 1 | | Number of items | 1 | | UPC | 746092904740 | | Unit Count | 500 gram | | Unit count | 500 gram | ## Product Details - **Brand:** Hugster - **Item form:** Powder - **Item weight:** 500 Grams - **Manufacturer:** Hugster - **Number of items:** 1 - **UPC:** 746092904740 - **Unit count:** 500 gram ## Images ![Gypsum Powder Food Grade - 500g - (Calcium Sulphate) for Homebrewing - Mushroom Growth - Hugsters (500)) - Image 1](https://m.media-amazon.com/images/I/61lC2VbGeFS.jpg) ## Questions & Answers **Q: If I buy now (March 2023) what will the best before date be?** A: January 2025 **Q: Can this be used to make tofu? e.g you can eat it after** A: If you mean do you add it to soy plants for growing it will almost certainly help their growth.
