Join Jo Webster and Caroline Gilmartin for a mind and taste-bud-expanding, hands-on fermenting experience on World Ferment Day.
What is JaJang? It is our take on a traditional KimJang; the longstanding practice of collectively making large quantities of kimchi for their community. It is basically a communal ferment-in. Only instead of making kimchi, we will be making Jo’s signature fermented veg. dish, the inimitable Jerusalem Artichoke ferment! Caroline says it is one of the nicest ferments she has ever tasted (and she has tasted a few). Join the fun fermentologists to make this ferment in an informative and collaborative communal setting, side by side with your fellow JaJang attendees.
We will learn a little about the history of KimJang, as well as gain insight into why you might want to continue to make and eat fermented vegetables on an ongoing basis and how to weave them into your life. Find out what World Ferment Day is all about and why the strapline for World Ferment Day is “have you got the guts?”.
Of course, you will also help make your own JA ferment to take home. And you will have the opportunity to eat fermented food in more ways than you might imagine! By the end of the day, you will be ready to continue your fermenting adventure at home, with your mind brimming with ideas and possibilities.
A delicious meal involving ferments awaits you at the lunch table to ensure you are inspired and energised for this unique event.
Once you've got the bug, there's no going back! This is a delicious and fun way to support your own health.
There is some capacity for concessionary places where they are needed. Please email if you would like further information.

Come appropriately dressed in comfortable clothes and footwear ready to make ferments. Please wear covered toed shoes.

The nearest train station is Bristol Temple Meads and 5 Cliftonwood is a 40 minute walk, a couple of buses or a cab ride from there. There is some parking a 3-4 minute walk away. Allow time to get parked.
If you want to make a weekend of it, Bristol is well worth the visit, as is nearby Bath and Wells.

The venue is Caroline’s delightful Clifton home, and she has just repainted her hallway especially!!
There is one step into the property, a ground floor loo and a pet cat.

Jo is an AFN registered associate nutritionist, a medical herbalist (with a special interest in gut health) and a fermentologist. Fermenting vegetables and fruits is a much-loved part of her fermentation practice. She is currently working on her PhD, the subject-matter of which is kimchi and earlier in the year, she visited South Korea, the home of kimchi. Jo is a proponent of being the change we want to see in the world and she founded World Ferment Day in 2025.
Caroline is a doctor of microbiology and the owner of Every Good Thing; a company that specialises in fermented food cultures and education. She is the author of two books on the subject; Fermented Foods, a Practical Approach and Vinegar (both published by Crowood). Caroline loves kimchi too and is the reason Jo is hooked on kimchi toasties!
They met several years ago when Jo organised a Guinness world record-setting Sauerkrautathon in Wells and Caroline came to help, they have been egging each other on ever since; partners in brine, you might say!

Just wanted to say a massive thank you for Friday. Your passion and contagious enthusiasm truly inspired both the chefs and me. We had an incredibly enjoyable training session and gained a wealth of valuable insights about fermentation and gut health. I can't wait to see what the chefs do going forward with their newfound knowledge and skills within the BM restaurants. - BM Caterers
