"Turn the glycol down and check back in the morning." 📉

If that’s your entire cold crash protocol, it might be the exact reason your lagers aren't clearing.

In our latest blog post, Slow Crash vs. Fast Crash, we explain why cooling speed matters just as much as how cold you go.

Slamming your glycol down too fast can cause proteins and polyphenols to flash-bind into loose, floating "microgels" that stay suspended indefinitely. Crashing slowly gives those same particles time to form dense, heavy structures that sink quickly (thanks to Stokes' Law).

The best part? The fix is a simple Step-Crash Protocol that costs absolutely nothing to implement.

MASTER THE QUICK SOUR! 🍋

Kettle souring is fast, efficient, and highly profitable—if you know how to dodge the pitfalls. In our newest episode, Richard and Mark drop the ultimate technical guide to Quick Souring with Lactobacillus.

What's on the radar:

✔️ The 3 Steps: Wort production, Lacto fermentation, and the optional second boil.
✔️ Defeating THP: Simple brewhouse steps to avoid "mousy" off-flavors.
✔️ Foam Safeguards: Why pre-acidifying to pH 4.5 saves your head retention.
✔️ The Battle: Pure Lacto cultures vs. primary souring yeasts.

Ever tried a beer that tasted "fine" but left you with a mild feeling of unease?

Your customers feel it too—and it’s probably costing you repeat business, even if they can’t tell you why. In our latest YouTube video, we look at Sub-Recognition Off-Flavours and why the human brain is evolutionarily hardwired to hate ambiguity in a glass.

The Brain Science Breakdown:

1️⃣ Detection vs. Recognition: There is a dangerous sensory gap where your brain registers something is there, but can’t identity it.
2️⃣ Weber’s Law & Contrast: Our brains are fine-tuned to look for contrast. In a delicate lager, even a tiny "invisible" flaw stands out like a scratch on a white wall (Signal-to-Noise Ratio).
3️⃣ Negativity Bias: Humans remember negative sensory experiences much longer than positive ones. An unidentifiable fault creates low-key consumer distrust that quietly drives people away from your brand.

Don't let cognitive noise ruin a perfectly good brew.

🎬 Watch the full video now to learn how to identify and fix the invisible faults hiding in your beer.

Have you ever had a beer that was technically clean, but just felt... "wrong"? You couldn't taste cooked corn, diacetyl, or rotten eggs, but something in you...

We went to the Craft Brewers Conference in Philly, gave a talk with Dr. Glen Fox, and realized one thing: Brewers have a lot of questions about yeast nutrition.

In today’s episode, Richard and Mark are giving a recap on the recent CBC session, giving answers to all those "deep-cut" technical inquiries. We’re moving beyond the basics and into the "nerdy" stuff that actually makes a difference in your cellar:

Inside the episode:
🧪 Zinc Secrets: To sterilize or not? (Plus oxidation risks).
🧬 FAN Fundamentals: Why your test results might be missing the full picture.
🚀 Future-Proofing: How today’s nutrients impact your next 5 generations.
🍺 The NA Strategy: Why non-alc brewing changes all the rules.

No fluff—just the technical "deep cuts" to help you master your cellar.

Ever had a beer that tasted "fine," but just felt wrong?

You can’t put your finger on it. It’s not buttery, it’s not rotten eggs... it’s just off. Today we’re talking about the "Sub-Recognition Zone"—a place where common lager faults hide and trigger a "red flag" in your customer's brain.

We’re breaking down why these "ghost" flavours happen and how a few simple process changes (and proper yeast nutrition) can help you brew with total intentionality.

Check out the blog for the full checklist:

Why does "vaguely off" beer trigger distrust? Learn how sub-recognition faults like DMS and acetaldehyde ruin lagers—and how to fix them with yeast nutrition.

Big flavour starts small. 🧫

Every world-class beer begins as a single colony, like this of Vermont Ale. Much like a brewery that started as a dream on a napkin, these cells are capable of incredible things once they hit the fermentor.

Whether you’re a small or massive powerhouse of a brewery, the power of a healthy culture is what makes the difference between "good beer" and "that beer everyone is talking about."

(Don't worry: this plate is for just for the close up!)

Pushing the limits of your Lager?

High Gravity brewing is the ultimate "cheat code" for brewery efficiency, but it comes with a technical price tag. In Part 9 of our Advanced Lager Techniques series, Nate Ferguson breaks down the science of High Gravity Brewing.

It’s not just about the ABV—it’s about the stress. Nate explains how high-density wort impacts:

Yeast Health: Osmotic stress and ethanol toxicity.
Wort Composition: FAN levels and nutrient availability.
Finished Beer Quality: Why your foam and body might be at risk.

If you’ve ever wondered if you should be diluting in the kettle or the cellar—or if you should be doing it at all—this video is for you.

Ever wanted to be a fly on the wall of R&D sensory at Escarpment Labs?

We’re putting two powerhouse dry strains to the test! In our newest podcast episode, Richard and Mark are joined by Production Manager and veteran brewer, Pat Wynn-Williams, to taste through an R&D APA brewed with some very special hops from Vinnie at Russian River.

It’s LalBrew Pomona vs. WLP079 Suava. Who wins on haze? Who wins on fruit? And how do you tweak your recipe to get the best out of both?

Inside the episode:
✔️ The technical differences between Pomona and Suava.
✔️ Increasing thiol expression (hello, Phantasm!).
✔️ Thinking outside the box: Alternative styles for these strains.
✔️ Minimal slurping noises (we promise).

For over 100 years, brewing has relied on the same narrow group of yeast strains…

…but that’s not the whole story.

This week’s episode explores the “living reservoir” of farmhouse yeast preserved by brewers across Northern and Eastern Europe.

And no—it’s not just kveik.

We dive into:
• The newly identified European Farmhouse yeast group
• What modern brewing has lost (and can regain)
• New research from leading yeast scientists
• The story behind WLP079 Suava Ale Yeast (https://buff.ly/IZwUYuD) with brought to market in collaboration with and

Old yeast. New science. Real implications for brewing today.
