The vast use of antibiotics and the chemicals in our food, even tiny traces of Roundup, destroy the balance in our intestine and bad bacteria take hold. The reestablishing of healthy bacteria is very difficult and can take months and even years.

Our microbiome is utterly complex. 70% of our immune system resides in the gut. The microbiome has many functions and even regulate our hormones.
We will discuss our microbiome in detail and show you many ways how to improve it through diet and lifestyle.

A vegetable ferment promotes the growth of healthy flora throughout the intestine. Each participant will prepare a ferment with fresh, organic vegetables on the day to take home.

We will enjoy a light lunch with fermented foods, herbs, fermented dairy and vegetables. The lunch is vegetarian with dairy, eggs and vegetables from KoruKai Herb farm. If you have dietary restrictions or allergies, please get in touch.

We will also learn how to make water kefir, probiotic yoghurt, milk kefir and a simple, fresh cheese brimming with billions of healthy gut bacteria.

Topics:

  • Our complex microbiome
  • Art and science of fermenting vegetables
  • Making a vegetable ferment
  • Water Kefir
  • Milk Kefir
  • Probiotic dairy yoghurt and cream cheese


What you will get:

  • Fermentation Booklet with information and recipes
  • 500g (approx.) of vegetable ferment to take home
  • Up to 10% off fermentation equipment (jars, glass weights, airlocks, wooden pounder)
  • Perpetual probiotic yoghurt starter culture
  • Nutritious and delicious lunch with a selection of handcrafted goodies from the farm including ferments, sourdough bread and probiotic cheese

Fabulous Fermentation Workshop

Wonderful day of learning with the addition of a delicious lunch <br /> Exceeded expectation, leaving with far more skills/knowledge than anticipated and equipment to get started

Amy Linton on  Jul 20, 2025

Again amazing

This is the second course I have done with this amazing family.. the drive over is awesome. The view is beautiful. The lesson itself is friendly relaxed and we laughed alot. You can ask questions when you need too. You can buy products no pressure. Came home with amazing ideas and lunch again was gorgeous. As a whole family they are a beautiful team full of inspiring ideas. Look forward to my next course :)

A great day out

A refreshing and insightful day in the art of fermenting. Cornelia has perfected this craft and made it accessible to a novice like me. My negative perception of fermented foods has taken a U turn - it can be delicious!!

Wonderful holistic learning experience

We got so much new information and learning from the fermentation workshop, in particular about making yoghurt and kefir drinks. Making our vegetable ferments was fun, especially with a small group of like-minded people, and working around the kitchen bench seemed so natural. Kai prepared a most delicious lunch of garden salad greens, freshly made sour dough bread with their home made butter, egg/vege frittata - and a selection of their amazing probiotic cheeses. It was lovely to share this with Nicholas and Julia too (Cornelia and Kai's children) - Nicholas had made one of the delicious cheeses!!! We loved seeing how the family all worked together ❤. Sadly we didn't get to look around the garden since it was very wet. This workshop was a real treat and we highly recommend it.

Excellent workshop

This workshop is a must do for anyone interested in nutrition and how fermented goods can improve your gut’s health. Cornelia will also explain why it is important to activate seeds & grains, and how to make simple and tasty recipes at home. Everything is well organised and I especially enjoyed the hands-on part, when we get to prepare our own sauerkraut. Not to mention the delightful lunch and afternoon tea with a great selection of homemade goods :)

Tina Troup on  Jul 6, 2020

Fermentation workshop

The day was inspiring and a lot of fun, with many good things to learn about making healthy food - everything starting with creating good soil to ways to prepare living and nutritious fermented food! Really enjoyed meeting Cornelia and her family and the other workshop participants - what an interesting bunch of people! The lunch was truly wonderful too.
