The Truth About Brewing Water Chemistry: Why pH Matters | QFPB E043
If you want the 10 minute check, comment “10 minute check” below and I’ll send it over.
For hundreds of years, brewing was a gamble. Same recipe, same ingredients… completely different results.
What changed everything wasn’t better ingredients or better brewers.
It was a single number: pH.
In this episode, we break down how the invention of the pH scale transformed brewing from guesswork into a precise, repeatable process—and how you can use it to dramatically improve your beer.
From mash efficiency to fermentation health, bitterness quality to final flavor—pH is the master control dial.
If you’re not measuring and controlling it, you’re brewing blind.
Here’s what you’ll learn:
- Why brewers struggled with inconsistency before pH
- The origin of the pH scale and why it matters
- Why pH is NOT a linear scale (and why that matters)
- The ideal mash pH range for enzyme performance
- How pH impacts boil performance and hop bitterness
- Why fermentation pH is your earliest warning signal
- The role of pH in final beer flavor and stability
- How to measure and adjust pH properly
- The most common mistakes brewers make with pH
