Ferment in the morning. Drum in the afternoon.
A two-part team day in a single venue out in nature: a lacto-fermentation workshop, a lunch built around ferments, then a drum circle. The only jam you'll meet is the kind that goes in a jar.

The idea
Fermentation, lunch and music, all in one place.
One venue, outdoors
Workshop, lunch and music all happen in the same place, outside when the weather allows. One trip there, one trip back, and nothing to organise in between.
Hands first, then the body
In the morning you chop, salt and taste. In the afternoon you move and play together. It's physical, but nobody needs trainers.
Two jars to take home
Everyone leaves with two jars of vegetables they prepared themselves. The souvenir keeps working on the shelf all by itself.
The day
Three parts, in the order you get hungry.
00 · Welcome
First, everyone arrives
A word of welcome, something to drink and an introduction to the day's programme: we take time to welcome everyone before the workshop begins.
01 · Morning
Lacto-fermentation workshop
An introduction to the world of ferments, led by Laurent. A little theory to understand what goes on inside the jar, then you look, smell and try.
02 · Lunch
A meal that puts ferments on the table
A menu built around the techniques from the morning, prepared with a partner caterer. You eat what you've just been talking about, which is rare at a company offsite.
03 · Afternoon
Drum circle
Everyone in a circle, an instrument in hand, and Zdenko in the middle. It works the body and the ears. No musical experience is needed, and the accounting team's sense of rhythm can be a surprise.
Your hosts
A fermenter and a musician. Both make noise, just not at the same time.
We host the day together, from the first hello to the last drumbeat. For us, how people are welcomed matters as much as the programme.
Laurent Cornu
Craft fermenter, founder of Fermentierra
With a background in brewing and wood-fired baking, Laurent has been fermenting organic vegetables in Western Switzerland for more than five years. He runs workshops and works with professional kitchens.
Zdenko Urban
Musician, drum circle facilitator
A Geneva-based musician, Zdenko is also a craft fermenter: he makes his own kimchi and explores Eastern European traditions. He sets the rhythm of the day, literally.
In their words
A warm welcome. A craft shared with care.
"Our company workshop was friendly, instructive and accessible."
"Laurent's course was a wonderful moment of learning and sharing."
"They arrive with jars, spices and passion."

Fermentierra's 5th anniversary
For our anniversary we ran a full day around fermentation: a talk by Sandor Ellix Katz, lunch, parallel workshops and a producers' market. Swiss radio RTS described it as a first fermentation festival for French-speaking Switzerland. That experience continues to shape the way we welcome each group.
