What does it take to brew award-winning hazy IPAs with half the dry hops most breweries use?

In this episode of The Escarpment Labs Podcast, we sit down with the Head Brewer of Willibald Farm Distillery & Brewery—and former Homebrew Lead at Escarpment Labs—to talk about the process behind their standout hazy beers.

We cover everything from the unique role water plays in their brewing approach to how careful yeast management drives flavour and consistency.

In this episode we discuss:

• How water chemistry shapes the character of Willibald’s beers

• Their strategy for harvesting and repitching yeast in hazy IPA production

• Why they use roughly half the dry hop rate of many breweries—and still achieve huge aroma

• Why New Zealand hops play such a central role in their hop program

• How yeast strains like Foggy London Ale, LalBrew Pomona, and LalBrew House Ale influence flavour expression

• When and why they retire a yeast pitch

• Brewing award-winning hazy IPAs in Copenhagen

• Advice for brewers looking to improve their hazy beers

We also tease an upcoming collaboration brew: EXP-666.

If you’re brewing hazy IPAs—or trying to make them more consistent—this conversation is packed with practical insights.

What does yeast have in common with Olympic athletes?

They don’t just show up and perform. They train.

In this episode of The Escarpment Labs Podcast, we sit down with former Escarpment Labs R&D Lead and current Assistant Professor of Molecular Biology at Carleton University, Dr. Eugene Fletcher, to break down the science of Lab Evolution — and how it’s shaping the future of brewing.

Eugene helped bring strains like KRISPY, Pomona, and TERPS to market. Now, he’s researching how brewer’s yeast can be evolved to break down plastic waste and turn it into biofuels.

In this episode, we cover:

• What lab evolution actually is — and why it’s like Olympic training

• How it differs from simple repitching

• How Pomona evolved from “okay” to a global strain partnership

• Why Saccharomyces is uniquely adaptable

• Lab evolution vs. GMO: advantages and tradeoffs

• The story of a Ghanaian strain sourced from traditional brewing

• What modern brewers — and even the non-alcoholic category — can learn from West African fermentation

If you’ve ever wondered how yeast adapts to hops, malt, pressure, or entirely new environments, this episode pulls back the curtain.

You’ve started repitching. Now let’s make it consistent.

In Part 2 of our Repitching Series, we move beyond the basics and introduce the core science behind repeatable, high-quality repitching: The Healthy Fermentation Formula.

Because pitch rate alone isn’t enough.

In this episode, we break down why traditional “cells per mL per degree Plato” thinking is incomplete — and why Cell Health and Wort Stress are just as critical to fermentation success.

We cover:

• The full formula:
  Healthy Fermentation = (Cells Pitched × Cell Health) ÷ Wort Stress

• What “Cell Health” really means (and how to observe it without a lab)

• The three biggest stressors: gravity, nutrient deficiency, and inhibitors

• Early harvest vs. post-cold-conditioning harvest — and why timing matters

• Why 2–5 PSI of CO₂ head pressure is non-negotiable during harvest

• How to upgrade your brink (and why stainless wins long-term)

• The simplest microscope-free measurement tool: Settled Yeast Volume (SYV)

If Part 1 helped you start repitching, this episode helps you stop guessing.

Hop creep has gone from an academic curiosity to a real, costly problem for brewers — but what’s actually happening inside the tank?

In this episode of The Escarpment Labs Podcast, we sit down with Jessica Young, PhD candidate at UC Davis (Food Science, Brewing) and former Cellar, Quality, and Sensory Manager at Bearded Iris Brewing, to break down hop creep straight from the science.

In recognition of International Day of Women and Girls in Science (Wednesday, February 11), this episode highlights the vital role women scientists play in advancing brewing knowledge and solving real-world industry challenges.

We cover:

• What hop creep actually is (and what it isn’t)

• Why it’s showing up more often now

• How hop variety and hop product type influence risk

• Whether starch from hops can become soluble in beer

• How harvest timing may affect enzymatic potential

• Practical mitigation strategies brewers can use today

• Why yeast cropping and mid-fermentation dry hopping matter more than you think

If you dry hop aggressively, care about stability, or want science-backed answers, this is a must-listen.

As brewers look to cut costs and improve consistency, yeast repitching is one of the highest-ROI process upgrades you can make.

In this beginner-focused episode of The Escarpment Labs Podcast, Mark and Richard break down why repitching works — and more importantly, how to start repitching without a lab, microscope, or complicated equipment.

We cover the non-negotiable fundamentals:

• How to choose a healthy “source batch” (freshness matters more than you think)

• The simplest harvest setup (a sanitized hose + a humble bucket)

• The single most important step to prevent off-flavours and repitch disasters

If you’ve been repitch-curious but unsure where to start, this episode is your green light.

What should a brewer do when seltzers keep going sideways—or when they just want a reliable, no-drama house ale?

In this episode of The Escarpment Labs Podcast, Mark and Richard cut through the noise to talk about the products and technical resources from Escarpment Labs that actually solve real process problems.

We break down how new releases like LalBrew® House Ale, Pink Boots Yeast, Seltzer Lightning, and our Non-Alcoholic Strain (LSB8001) are designed to make brewing more predictable, more consistent, and less stressful—without sacrificing flavour.

We also dive into our newest Yeast Nutrition & Repitching Guides, sharing the two non-negotiable checks every brewer should be making, and preview what’s coming next in our Experimental Strain Program.

If you’re tired of firefighting fermentations and ready to make your process easier, this episode is for you.

What should every brewer’s Brew Year’s Resolution be for 2026?

In this episode of The Escarpment Labs Podcast, Mark and Richard talk about what really moves the needle in fermentation: process refinement over novelty.

We break down the five most impactful resolutions brewers can make this year—from mastering yeast nutrition and controlling pH, to dialling in pitch rate, oxygen, and strain-specific stress limits. These aren’t flashy changes—but they’re the ones that turn inconsistent beers into reliable, repeatable “clone” batches.

If you’re ready to stop chasing fixes and start brewing better beer on purpose, this episode is your new blueprint.

What if the future of beer looks less experimental — but also more thoughtful, more intentional, and more serious — than it has in years?

In this special forecasting episode, Mark and Richard channel “Yeastrodomus” to predict the biggest brewing and culture shifts coming in 2026. From beer trends to consumer behaviour to brewing philosophy, we explore why the next wave of craft isn’t about novelty… but about mastery, experience, balance, and brand coherence.

We dive into:

• Why the industry is shifting from constant reinvention to better-over-new

• How the experience economy’s return will reshape taprooms

• The rise of fruit beers that aren’t sours (finally!)

• Why pasteurization is no longer a dirty word in craft

• The growth of staff-led side brands

• The visual language of animal beers, celeb beers, and semiotics on shelves

• The growing movement toward genre-less beer

• And why English pub vibes and session culture are coming back strong

2026 won’t be boring — but it may be quieter, smarter, and more delicious than the last decade of hype cycles. Let’s look ahead.

If we graded the fermentation decisions made across hundreds of breweries this year… what would land on the nice list, and what would definitely land on the naughty list?

In this special year-end episode, Mark and Richard look back at 2025 through the lens of customer troubleshooting data, industry trends, lab insights, and Escarpment’s own milestones — from our 10th anniversary and new product launches to global podcast stats and community wins.

We break down the practices that led to the cleanest, most consistent beer of the year… and the shortcuts that consistently caused sulfur, haze, stalls, and headaches. From oxygen management and yeast health to propagation pitfalls and pH discipline, this episode is both a celebration and a reality check for brewers heading into 2026.

Whether you’re looking to tighten up your fundamentals or avoid the “naughty list” entirely, this episode will help set you up for a more stable, more successful brewing year ahead.

Why do some lagers smell like rotten eggs, cooked corn, or burnt matches — and how do you actually fix it? In this episode, Mark and Richard walk through one of the most misunderstood (and most feared) parts of lager brewing: sulfur compounds.

Using key insights from Nate’s recent video Advanced Lager Techniques: Navigating Sulfur in Lager, we explore:

• The difference between “good sulfur” and sulfur faults

• The five major sulfur compounds found in beer

• Why yeast makes sulfur in the first place

• How to diagnose sulfur by aroma (your nose is your best instrument!)

• Process levers — oxygenation, FAN, pitch rate, temperature, spunding

• Cleanup strategies that work (and when it’s too late)

Sulfur is a normal part of lager fermentation — the goal isn’t zero sulfur, but controlled sulfur. This episode helps you understand which compounds belong, which don’t, and how to keep your lagers clean, complex, and stable.

Why does a beer that should be brilliantly clear suddenly pour cloudy — even when you swear nothing changed in the process? In this episode, Mark and Richard dig into one of the most common (and frustrating) brewery questions: unexpected haze.

Using key insights from our Knowledge Base article Troubleshooting Haze: Unexpected Hazy Beer, we break down the different types of haze, how to diagnose them quickly, and — most importantly — how to prevent them from happening in the first place.

From yeast that won’t drop out, to protein–polyphenol complexes, to starch haze caused by mash drift, we walk through root causes and practical interventions at every stage of brewing.

This episode gives you the clarity you’re looking for — literally.

Brewing great non-alcoholic beer is not as simple as stopping fermentation early — and doing it safely requires a completely different mindset. In this episode, Mark and Richard walk through what NA beer actually is (legally!), why the category is exploding, and how craft breweries can make high-quality, microbiologically safe NA products using real fermentation.

We break down the risks, the safest production paths, and why maltose-negative yeasts like Hanseniaspora uvarum and LoNa are changing the game. And yes — we explain why you must pasteurize.

This episode follows along with our new Guide to Non-Alcoholic Fermentation — download it and learn step-by-step how to build safe, stable, drinkable NA beer.

What if your taproom’s best-performing new beer next year isn’t a double IPA, but a 3.5% crusher that customers can’t stop ordering?

In this episode, Mark and Richard dive into the rise of mid-strength beer — flavourful, balanced, and built for today’s drinkers. From brewing science to taproom strategy, we break down why these beers are gaining traction and how to make them shine.

You’ll learn:

• What defines a mid-strength beer and why the term matters.

• The brewing challenges at lower ABV (and how to solve them).

• Strategies for yeast, hops, and body to keep flavour big and drinkability high.

• Why moderation and “second pint culture” are the next wave in craft beer.

Whether you’re exploring table saisons, hoppy pub ales, or crushable lagers, this episode will inspire you to think small — and brew big.

Big beers demand big planning. In this episode, Mark and Richard tackle the challenges of high-gravity fermentations — where yeast faces the toughest conditions and even small mistakes can lead to stuck or stalled ferments.

Drawing from real troubleshooting experiences (including a triple IPA gone rogue), we explore why high gravity stresses yeast, what’s happening inside the cell, and how to prevent fermentation collapse before it starts.

You’ll learn:

• Why oxygenation and nutrient balance matter more than ever.

• The role of zinc, magnesium, and sterol reserves in stress tolerance.

• How to prep yeast and choose the right strain for strong wort.

• What to do (and not do) if fermentation stalls.

Whether you’re brewing a 10% barleywine or pushing the limits with an imperial stout, this episode will help you get to full attenuation — without the panic.

Featured in this Episode:

• Effects of magnesium on yeast stress tolerance (Walker, 1994)

• Oxygen and sterol synthesis in brewing yeast (Verbelen et al., 2009)
• Products: Yeast Lightning for beer specific nutrients, our Kveik Strains like Voss or Hornindal for barley wines, LalBrew® House Ale for Imperial Stouts, and West Abbey Ale for High Gravity Belgium beers.

What if the secret to more consistent, stable, and better-tasting beer isn’t a new yeast strain or a fancy sensor — it’s just controlling your pH?

In this episode, Mark and Richard break down why pH is the quiet backbone of brewing, tying together mash performance, fermentation health, hop creep, stability, and even how your dry hop behaves. From mash targets and pH drops during fermentation to how pH changes with dry hopping and packaging, we walk through the key checkpoints brewers should measure and actually act on.

We also tackle the classic homebrew debate: pH strips vs. pH meters — and why stepping up to a proper meter can transform your consistency.

If you’re serious about taking your beer from good to great, this episode will convince you that pH is the number you can’t afford to ignore.

Now that we’ve built the foundation of process and philosophy, it’s time to meet the culture itself — the community of microbes that defines mixed fermentation.

In Part 2 of our Mixed Fermentation Manifesto series, Richard dives deep into the living side of the art: Saccharomyces, Brettanomyces, Lactobacillus, Pediococcus, and the wild microbes that make mixed-culture beer what it is. We explore how these organisms interact, what flavours they bring, and how to feed and guide them toward balance instead of chaos.

You’ll also hear practical insights on water, grains, hops, fruiting, and blending — everything that shapes the long, evolving story of flavour in mixed fermentation.

Because in the end, the goal isn’t acidity or funk — it’s harmony.

Mixed fermentation isn’t a style — it’s a philosophy. In this episode, Richard kicks off our two-part Mixed Fermentation Manifesto series by exploring what it means to brew with multiple microbes working together. From fast-turn mixed cultures to long-aged sours, we look at how balance, not chaos, defines great mixed fermentation.

You’ll hear about process foundations — creating “food for the culture,” managing raw grains, oxygen, time, and patience — and why successful mixed fermentation is more about nurturing an ecosystem than following a recipe.

We’ll also walk through a few practical examples (including the Infinite Improbability Drive method) and talk through vessel choice, blending philosophy, and why time itself might be the most important ingredient.

Next week is Part 2 !

We'll dive deeper into the microbes behind the magic — who’s living in your beer, and how to build the flavours you want.

Brewing lagers at 8°C — just like old-world brewers — is making a comeback. But how do you balance tradition with modern efficiency?

In this episode, Mark and Richard unpack a study testing four lager strains at three different pitch rates to see how fermentation performance and flavour hold up under cold conditions. From the surprising strain-dependent results to practical recommendations for brewers, this is your guide to brewing clean, crisp lagers at low temperatures without sacrificing time or quality.

  Carlsberg: The Pursuit of the Perfect Beer

What if that sluggish fermentation or unexpected haze in your lager isn’t about your yeast strain or your malt, but about two overlooked minerals: zinc and magnesium?

In this episode, we dig into why zinc and magnesium are essential for healthy fermentations, crisp finishes, and consistent flocculation. From their biochemical roles in yeast metabolism to real-world troubleshooting tips, we break down how these overlooked minerals can make or break your lager.

You’ll learn:

• Why zinc is critical for alcohol dehydrogenase, flocculation, and fermentation speed.

• How magnesium stabilizes ATP, enzymes, and cell walls for yeast health.

• Practical dosing strategies — and why more isn’t always better.

• When and how to use balanced nutrients like Yeast Lightning.

Whether you’re brewing with adjuncts, soft water, or pushing lager fermentation under pressure, zinc and magnesium might be the missing keys to dialling in your beer.

Oxygen is essential to great fermentation — but getting it wrong can throw off your entire batch.

In this episode, Mark and Richard explore how oxygen impacts yeast health and performance, why when and how you oxygenate really matters, and what tools brewers can use to dial it in. From shaking a carboy to inline sintered stones and DO meters, this one’s packed with tips for brewers at all levels.

Learn how to avoid sluggish ferments, off-flavours, and repitching issues — and breathe new life into your fermentation process.

What’s the big deal with pitch rate — and why does it confuse so many brewers?

In this episode, Mark and Richard break down what pitch rate really means (beyond the numbers) and why it’s one of the most critical levers in fermentation. From underpitching risks to strain-specific stress tolerance, we’ll help you navigate the numbers, avoid common pitfalls, and dial in your approach whether you're brewing 20 litres or 20 hectolitres.

We also explore how pitch rate can be used intentionally to shape beer character — and what makes strains like Kveik so unique when it comes to pitching flexibility.

In our very first episode, we're diving into a trend that’s gaining momentum in both pro and homebrew circles: pressure fermentation.

What is it? Why are more brewers trying it? And how can it improve your beer?

Mark and Richard unpack the science and strategy behind fermenting under pressure — from the basics (spunding valves, CO₂ buildup) to the real-world benefits (faster turnarounds, cleaner profiles, and natural carbonation). Plus: tech tips, yeast considerations, and why this method might be a game-changer for lagers, NEIPAs, and beyond.

Whether you're pressure-curious or already experimenting, this episode will help you ferment with confidence.
