Why would I ever fry and eat my SCOBY? It would be like murder! : Attuning to nonhumans through kombucha fermentation practices

Kombucha fermentation is a multispecies activity guided by human-microbe
interactions. This study investigates kombucha fermentation practices as a platform to recognize relationality with nonhuman microbes. For this, relational theories enable reframing human-microbe relations by focusing on reciprocity and interconnectedness within multispecies relations. The empirical research consists of interviews, a design probing task, and a collective reflection workshop with kombucha brewers. The empirical research delivers insights into the agency of microbes, sensory experiences, and embodied knowledge in kombucha fermentation practices. Findings investigate how humans attune to the needs of microbes, and the role of embeddedness in ethical doings. In this way, the study explores alternative ways of relating to nonhumans beyond prevalent human exceptionalist mindsets in design and sustainability. By interpreting the research findings, the research proposes methodological and theoretical implications for designers to enable recognition of relationality with nonhumans.
