Louisville Water Reports

Water is one of the main ingredients in brewing and can make or break your beer. Water pH is important for efficient mashing and to fine-tune the flavor of your beer. You can read more on the importance of adjusting your water profile, tools to help you, and more on what these numbers mean here. LAGERS members have given presentations on water chemistry, which are available free of charge. If you have any more questions about water chemistry or the information provided here, feel free to contact us.

As the city does not provide up-to-date water reports, we rely on laboratory testing in order to determine the water profile of Louisville’s tap water. Louisville has two water treatment plants, and they blend and treat the water output in order to get a consistent profile. This means that your water will not change much throughout the seasons.

Laboratory testing in two locations on opposite sides of Louisville gave similar results. The average of the two results are below, and you can also see the reports themselves.

Ca: 33 ppm | Mg: 12 ppm| Na: 21 ppm| SO4: 21 ppm| CL: 23 ppm| HCO3: 78 ppm | pH: 8.3

If you have performed a water report, please contact us so we can continue to provide up-to-date information.
