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.
