The Escarpment Labs Podcast

The draft is over, the rosters are locked, and now it’s time to actually build the business.

In Part 2 of our Ultimate Yeast Fantasy Draft, Mark and Richard take their 5-strain yeast lineups from last week and put them to work. The challenge is strict: design a competitive, 10-to-12-beer mainstay taproom menu where every single strain must be featured at least twice.

Things get wildly creative as the hosts reveal their complete...

If you could start a brand new brewery tomorrow with a blank slate, which yeast strains would you stake your business on?

Over 90% of breweries in North America operate as small, nimble taproom models. In this environment, your yeast isn't just a fermentation agent—it's your most flexible employee. It needs to turn tanks fast, adapt to multiple styles, and deliver standout flavour profiles without creating absolute chaos in th...

We spend all our time choosing the perfect hops and dialing in our water profile—but are we treating our yeast like an afterthought?

A few weeks ago, we did a massive, deep-dive Q&A on yeast nutrition. But after our joint presentation with Dr. Glen Fox at the Craft Brewers Conference, a lot of brewers reached out asking for a quick, "high-level" breakdown of the fundamentals. On this short and sweet episode, Richard takes ...

Kettle souring doesn't have to be a gamble. If you’ve ever been haunted by a "mousy" off-flavour or a stuck fermentation, this episode is your roadmap to safety.

In this complete guide, Mark and Richard break down the fast, controlled method of quick souring using pure Lactobacillus cultures. We demystify the entire process, walking through the three essential pillars—wort production, bacterial fermentation, and the opti...

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 this episode, Mark and Richard recap their recent CBC session on Yeast Nutrition, Zinc, and FAN. Because the live Q&A was so packed with "deep-cut" technical inquiries, we decided to bring those questions back to the lab for a dedicated Yeast Nutrition Lightning Round...

Ever wonder what happens when Vinnie from Russian River sends you a care package of hops? You brew a side-by-side trial, obviously.

In this episode, Richard and Mark are joined by Escarpment’s own Production Manager and brewing veteran, Pat Wynn-Williams, for a deep dive into the glass. We’re tasting through an R&D American Pale Ale split between two heavy-hitters that we developed in the dry yeast world: LalBrew Pom...

For over a century, brewing has relied on a narrow band of industrial yeast monocultures.

But outside the lab, a different story has been quietly unfolding.

In this episode of The Escarpment Labs Podcast, we explore the “living reservoir” of yeast diversity preserved by farmhouse brewers across Northern and Eastern Europe—and why it matters more than ever.

We cover:

• What defines the newly identified “Europea...

Dry yeast has come a long way—but not all strains (or packs) are created equal.

In this solo episode of The Escarpment Labs Podcast, Richard answers some of the most common questions brewers have about dry yeast—what it does well, where it falls short, and how it compares to liquid cultures in modern brewing.

We cover:

• The relationship between ...

You’ve started repitching. You understand cell health. Now it’s time to eliminate the last 5%: troubleshooting and buy in from ownership and finance.

In the final episode of our Repitching Series, we move into advanced troubleshooting, optimization, and financial modelling — because repitching isn’t just a technical decision. It’s an operational one.

We cover:

• How to identify and eliminate the final 5...
