Proper selection of the raw materials for brewing has a considerable impact on beer quality, and | Proper selection of the raw materials for brewing has a considerable impact on beer quality, and water is no exception. Brewers have options for sources of brewing water, including RO water and tap water. Some brewers may wish to blend two water sources to achieve a more desirable mineral profile. For example, tap water can be blended with RO water to reduce the alkalinty, perhaps achieving a proper mash pH without needing to further adjust the water minerals or acid/base. Simple blending calculations apply. However, in most cases, it's easier to simply use RO water if you have access to it. | ||
