In this talk, gastronomist and founder of The Fermenters Guild UK, Robin Sherriff, will open up the jar to fermentation and explore the science behind the mysterious process. He'll explore the real chemistry and biology behind miso, shoyu, kimchi, cheese, beer, vinegar, kombucha and more: enzymes, acids, alcohols, gases, and the microbial communities that make them. He will also demystify the difference between “alive”, “safe”, and “tasty”, and why those are not always the same thing.
Tracing the journey from raw ingredient to something deeper, safer, and more delicious, Robin will show how temperature, salt, oxygen, time, and cleanliness steer the process. Expect a practical, flavour-led tour of what is happening in the dark, plus a few simple rules of thumb for repeatable results.
Following the lecture, small samples of featured foods will be available to try to engage your gastronomical senses as well as your mind.*
Copies of Robin's book "The Science of Fermentation" will be available to purchase after the talk.
*Food samples are subject to availability. Those with food allergies and intolerances should speak to a member of staff before consuming anything. The Royal Institution accepts no liability for any adverse reaction caused.

About Robin Sherriff
Robin Sherriff is the founder of The Koji Kitchen, a developmental food lab and educational space in Scotland, and he founded The Fermenters Guild UK to support the growing fermentation community through shared learning and practical advocacy.
Robin started out in Chemistry and Biology, then took the long route through kitchens, bars, production sites, and research roles, building a grounded understanding of process, people, and food systems. An MSc in Gastronomy pulled those threads together, with thesis research in Kyoto on Japanese whisky aesthetics opening the door to saké, then koji. Alongside writing and teaching, he co-runs Slow Sauce, a Scottish miso and shoyu brewery working with oats, peas, and oak barrels. He wrote The Science of Fermentation to make fermentation make sense: the microbes, the method, the safety, and the flavour.
