'It was very very good': Ötzi the Iceman's body is covered in ancient yeast — and scientists just used it to make a sourdough

A recent study revealed that scientists cultivated four strains of cold-adapted yeasts from Ötzi the Iceman's body, which dates back 5,300 years and was discovered in the Alps. These ancient yeasts were used to successfully bake sourdough bread, showcasing the preservation of biological materials over millennia.

This development is significant as it not only demonstrates the potential of ancient microorganisms in modern culinary practices but also offers insights into the life and culture of prehistoric Europeans, enhancing the understanding of their dietary habits.

The use of ancient yeast in baking highlights a growing interest in the intersection of science and gastronomy, as researchers explore how historical biological materials can inform contemporary food production and cultural heritage, reflecting a broader trend of utilizing ancient resources in modern applications.
