“How do I know when the flavor of my beer is out of spec?”
I get this question a lot, and it truly is a fundamental question if your goal is to consistently brew great beer. Because of this, breweries need an easy AND objective way to tell if a given batch hits the flavor profile expected. This type of test has many names (e.g. go/no go, true to brand, TTB, etc.) and there are many approaches, all detailed below, but none so easy and powerful as using percent defect charts (p-charts for short).
Here’s what you’ll learn from this post:
- The different approaches of how to measure batch-to-batch variation
- Why we recommend p-charts
- An easy to understand guide with expert tips for using p-charts in your brewery
