Let’s chat about your water!
Step 1: Obtain Your Water Profile
Obtaining your water profile is an essential step in understanding the key characteristics of the water you will use for brewing. There are several methods to acquire this information. One option is to reach out to your local water utility or municipality and inquire about the water quality report for your area. This report typically includes data on mineral content, pH levels, and other relevant parameters. Alternatively, many homebrewers rely on reputable laboratories such as Ward Laboratories for comprehensive water analysis. These specialized facilities offer tailored testing services specifically for brewing purposes. By sending a water sample to Ward Laboratories or a similar establishment, you can receive a detailed water profile report, providing you with the insights necessary to make informed decisions and adjustments in your brewing process.
For the purpose of this article, I’ll be leveraging the detailed water report I received as a PDF file from Ward Laboratories in 2021 which captured essential information about the mineral composition, pH levels, and other relevant parameters of my brewing water at the time.
Step 2: Enable the PDF Plug-in for ChatGPT
