Two days Fermenting foods and drinks, San Mateo - Costa Rica Fermentation is a natural transformation process in which microorganisms such as bacteria and yeasts convert sugars into beneficial compounds. For thousands of years, cultures around the world have used fermentation not only to preserve food, but to enhance flavor, increase digestibility, and improve nutritional value. Fermented foods play a fundamental role in supporting our microbiota and strengthening overall well-being, reconnecting us with ancestral knowledge and living traditions.During this immersive course, we will explore fermentation processes in depth — understanding how they work, their history across cultures, their nutritional importance, and their impact on gut health.
