The essentials
Learning by doing
Sharing knowledge is central to Fermentierra. We make fermentation easy to understand and give everyone the foundations to experiment.
Our workshops are a journey of doing, tasting and sharing. Laurent blends precision, stories, humour and improvisation into a welcoming, accessible experience.
Beyond technique, they are places to meet and talk about food, microbes, traditions and seasons — and to gain the confidence to continue at home.

A gem worth discovering! A varied range of original, delicious organic ferments and excellent customer service.
Five well-deserved stars! I loved the course and now order regularly. The sea sauerkraut is my favourite.
