Crack the Code: What a Malt COA Is, Why It Matters, and When to Use It

Do you actually know what's in your malt? In this episode of The Beer Craft Podcast, Ben and Andrew crack open the mysterious (and often ignored) Certificate of Analysis—the COA—and show you how to use it to level up your brew day.

Whether you're designing a recipe, troubleshooting a stuck mash, or just trying to brew the same great beer twice in a row, understanding your malt's COA can save you time, money, and stress. We break down:

What a COA is—and what it's not
When you should actually look at it
What those weird acronyms mean (FAN, DP, SRM, Kolbach…)
Real-world ways to use it in your brewing software and process
How to troubleshoot fermentation and mash issues with confidence

Plus, we've got some killer extras for you:
