What does it mean to steward a living archive? Kyria Boundy-Mills, curator of the Phaff Yeast Culture Collection, joins Esculent to discuss the care and preservation of thousands of yeast strains. The collection extends far beyond familiar fermenters like bread and beer yeasts, encompassing species drawn from insect ecologies, plants, soils, and unexpected environments.

In this episode, we explore how yeasts become technologies of esculence, such as how isolating, storing, and characterizing microbial life supports food science research. Boundy-Mills’ work reveals the archival dimensions of microbial collections, and what infrastructure is utilized to maintain those archives.

What happens when the science of winemaking meets the emerging world of cultivated meat? Distinguished Professor David Block joins Esculent to discuss how engineering principles, chemistry, and scale shape technologies of taste. This episode also considers mouthfeel—how the tactile sensation of food and drink becomes central, or is becoming central, to the experience of the esculent in the food industry. Together, we reflect on how scaling, precision, and sensory expectations intersect in both traditional and experimental forms of food production.

Microorganisms structure not only our foods but our bodies. Professor Maria Marco joins Esculent to discuss her research on bacteria, fermentation, probiotics, and the gustatory systems that support microbial life. While microbes often appear in consumer culture as wellness buzzwords, Professor Marco offers a another perspective on how microorganisms function as part of systems of eating.

This episode examines how microbes participate in the making of the esculent, and the questions that linger on the edges of studying nonhuman participants in processes of eating.
