About Us
We are brewers, scientists, and fermentation enthusiasts.
We believe in producing high-quality cultures that you can trust.
Because we learned by doing, we speak with confidence and act with skill to help you grow your craft and brew your best. We start with yeast and end with a thriving community of scientists, entrepreneurs, makers and devoted consumers.
Our products taste of
pride and friendship
Founders Angus Ross, Nate Ferguson and Richard Preiss met while working in a yeast research lab at the University of Guelph.
A collective love for beer and brewing led them to found Escarpment Laboratories, intending to add value to the craft beverage landscape and hang out in breweries for a living.
Our purpose:
Harnessing the science of cultures.
Since 2015, Escarpment Laboratories has helped hundreds of breweries achieve their fermentation targets. We grow our reputation as industry leaders by innovating every single day and teaching as we learn.
Richard Preiss
Richard is a brewing scientist with a MSc. in Molecular Biology and Genetics. At Escarpment, Richard manages our customer service, sales, and R&D. You may encounter him on the road, presenting on various yeast science topics. In his role as CEO, Richard loves to help our team and the brewers we work with to solve problems, overcome challenges, and unlock efficiencies. One day, Richard will write a manifesto on mixed fermentation beers. His favourite beer styles are German Pilsner and Saison, the latter of which is a style he assures everyone is "not quite dead".
Nate Ferguson
Nate Ferguson is a co-founder of Escarpment Labs and a professor in the Brewmaster and Brewery Operations Program at Niagara College, where he bridges the worlds of applied research and hands-on brewing education. At Escarpment Labs, he focuses on yeast science and helping brewers understand the why behind their process — not just the what.
Angus Ross
Cofounder Angus Ross launched the idea for Escarpment Labs, based on the clear need for a domestic Canadian yeast lab for craft brewers. In the early days, Angus did it all: propagation, sales, marketing, cleaning pumps... Today, Angus manages human resources, finances and sales at Escarpment. Angus is a big fan of funky, Bretty beers.
Luisa Muhleisen
As Quality Manager, Luisa brings over 15 years of laboratory experience to Escarpment Labs, including past chapters as an analytical chemist and commercial brewer. Her unique background even features a stint as an ice cream business owner, giving her a deep appreciation for the science of flavor. When she isn't keeping our quality standards world-class, she loves catching live theatre and finding well-crafted pints.
Patrick Wynn-Williams
Patrick joined Escarpment back in 2019 after working in several breweries in Ontario and Quebec, and has held many positions with us over the years. With a background in brewing and a degree in Food Science from the University of Guelph, he's been overseeing Production at Escarpment since January 2025. In his spare time, he's likely engaged in the Sisyphean task of pulling weeds in his garden.
Attilio Consigli
Attilio was a graduate of UoG's Microbiology program when he found his way to Escarpment Labs. He began his career in Fulfillment, but has now discovered his place in the Quality Control Lab. He keeps the lab running smoothly by ensuring all yeast props are healthy, hyper-performing, and entirely contaminant-free. But his impact doesn't stop there — Attilio is also the brains behind many of Escarpment's eco-friendly initiatives, from compostable packaging to product upcycling. When he isn't saving the planet one batch at a time, you'll find him at the gym, playing rec soccer, snowboarding, or volunteering for environmental groups.
Chris Waterton
Chris' passion for craft beer started many years ago. His knowledge was forged and strengthened during his time in the brewing program at Niagara College. That knowledge reflects in his daily responsibilities at Escarpment, ensuring brewers of all types are free of concern.
Nicole Irvine
As our Marketing Lead, she’s the one working behind the scenes on everything you see, from emails and social media to editing podcasts and videos. Armed with a Communications degree from Carleton University and a post-grad in Brand Management from Algonquin College, she puts her skills to work making the wonderful world of yeast look incredibly cool. Off the clock, she’s usually perfecting her homemade pizza skills, hitting the ice with her synchronized figure skating team, or scouting new restaurants and breweries for "market research."
Shelley Beirnes
Shelley is an optimistic and enthusiastic Account Manager on our Sales team with over 25 years spent in the brewing industry, on both the brewing and supply/manufacturing sides. When she's not visiting with our customers and talking fermentation, she's spinning vinyl, camping in her van, or watching Everton FC do Toffee-like things. She appreciates a good campfire spent with friends.
Mark Korczynski
Marky is our big teddy bear, helping brewer's figure out their problems when they may be highly stressed. He is always there to answer questions and make suggestions to the brewers. His calmness under pressure and positive attitude translates from his work life to his hobbies as he can be seen performing in his band Wreckless Harbour all around the GTA area.
Emily Storey
Emily is Escarpment Labs' data fixer, automation designer, and all-around computer wiz. Since a lot of the lab's data and software needs are a square-peg-round-hole fit for off-the-shelf programs, her job is to bridge that gap and design custom tools that help the team grow your yeast, keep quality top-notch, and anticipate what you need before you do. Just don't ask her to fix the printer—she doesn't know why it's making that noise either.
Camille Regimbal
Camille's main focus at work is making sure the team successfully gets the yeast out of the tanks and into your beers. She and the harvest team also handle critical quality control work before any product leaves the facility. In her free time, you can find her enjoying the outdoors on a hike, or settling in with a cross-stitch or crochet project.
Medea Romani
Medea is our Production Lead. She graduated from the Brewmaster program at Niagara College in 2023 and has been working in breweries ever since, joining our team in 2025. With a passion for all things brewing, she's especially fond of stouts, and is always eager to explore new flavours. When it comes to producing yeast, she’s fast as lightning (pun intended).
Emily Tomkinson
Emily is our Production and Harvest Specialist, aka, Escarpment jack of all trades, master of none. She studied microbiology at the University of Guelph and before Escarpment worked mainly in the research side of science to develop her brain muscles. Her off-hours are ideally spent enjoying nature through backcountry camping, biking or reading in a park.
Zachary Harlaar
Zachary is our Accounting Technician. He looks after the daily finances for Escarpment Labs, making sure everything is accounted for. Zachary comes at the beer industry strictly from a numbers perspective. At home he likes to hang out with his wife and kids, go on long walks, and crunch numbers late into the night.
Cole Raiskums
Cole oversees laboratory operations, managing everything from yeast growth to quality control, while leading a dedicated team of three to produce top-tier yeast. He also manages Escarpment's external QC program, drawing on his experience setting up QC programs at three previous breweries to help customers brew safe, high-quality beer. He’s learned a lot along the way, so if you ever want to talk beer quality control, he is always down to chat!
Christine L.
At Escarpment Labs, Christine supports the sales team and helps navigate the intricate logic of production operations. Her role involves balancing customer demand with tank capacity to ensure core strains are consistently in stock and ready to ship at a moment's notice. She’s a self-proclaimed logistics nerd who loves the puzzle of a perfect schedule, but outside the lab, she happily trades the spreadsheets for fiber arts like knitting and weaving.
