What are you going to learn?

  • An understanding of wild ferments and their benefits

  • The propperties and benefits of the wild herbs we will use to prepare our recipes.

  • You will make vinegar, yogurt, vegetable milk, curd, wild kombucha and slow cheese using fruits and leaves from the forest.

  • To know and solve the most common problems in fermentation: molds, yeasts, excessive curdling, oxidation, etc.


  • I do not have experience in fermentation, is this course for me?

    Yes, specially because is a “basic” course, an initiation into fermentation to those who does not have the knowledge about this culinary technique.

  • I do not have knowledge in Wild Medicinal Herbs.

    Although in this course we are going to collect certain plants in situ and none of them can be confused with a similar herb that is toxic, it is highly recommended that you get a good book on identification of wild plants or at least know how to distinguish well the herbs we are going to use in the recipes.

  • Which plants are we going to use?

    1. Nettles (Urtica dioica L.) 2. Blackberry (Rubus ulmifolius Schott.) 3. Wild Rose (Rosa canina L.) 4. Chestnut (Castanea sativa Mill.) *Blacbkerry could be replaced by Raspberry (Rubus idaeus) or Wild Straberry(Fragaria vesca L.). If you have these herbs in your area, then you can do the course!

  • What happens if during fermentation mold appears or I have any problem?

    Fermentation is generally a totally safe and easy process to carry out. At any rate, in each of the recipes there will always be a "File" where it will be an explanation of the most common problems and how to solve them.
