In this class, we'll explore sources of wild yeast and bacteria and the best ways to shepherd them in your ferments. We will make delicious beverages that offer both complexity of flavors and the health benefits of a diverse microbiome. Drawing on traditions from Mexico, Europe and the Caribbean, we will explore foundational recipes and experimental variations.

This class is led by Karen Wang Diggs, a classically trained chef and nutrition consultant specializing in gluten-free baking and fermented foods. She is also the inventor of Kraut Source, a device that makes small batch lacto-fermentation super easy using mason jars.
