Science of Haze: Part 2 | The Craft Equation Podcast

In Part 2 of The Craft Equation, we dive deep into the real science behind hazy IPAs — not just what they look like, but what physically and chemically makes haze form, stay suspended, and remain stable from tank to package. Joined by Chris Baker, Director of Brewing Operations at Mother Earth Brew Co., we break down the technical side of haze formation: protein–polyphenol interactions, wheat and oat percentages, dextrin malts, yeast strain selection, and why heavy dry hopping plays a bigger role than most brewers think. We also talk through the lessons we learned the hard way — early beers that cleared up, the “snow globe” effect, and the process changes that helped us dial in consistent, shelf-stable haze across our Project X Series. You’ll learn about: • Chill haze vs. permanent haze • Protein + polyphenol chemistry • Wheat, oats, and dextrins for mouthfeel and stability • Hot side hopping vs. dry hopping strategy • Fermentation dry hopping + biotransformation • Yeast impact on haze (including Imperial A38 “Juice”) • Finding agents, centrifuging, and packaging consistency • Why some brewers still prefer West Coast IPAs We crack open our latest Project X hazy and walk through the real-world process decisions that shape what ends up in your glass. If you’re brewing hazy IPAs — or just want to understand what’s actually happening inside them — this one’s for you.
