5² is a proprietary blend of food-grade phosphate buffers (similar to brewer’s salts) that will lock in your mash and kettle water at a pH of 5² regardless of the starting pH of your water. 5² is safe for your mash and WILL NOT add any flavors to your beer. 5² will provide consistency of pH in any water conditions, but the most significant gains will be obtained if you are brewing in hard water.


Use 5² at a rate of approx 9g for 5 US gallons of water. Calculate the amount of water based on the total volume in the kettle. Place 5² in the mash tun while you are mashing in. If desired, dissolve in a small amount of water before adding to the mash.
