At Masala y Maíz in Mexico City, no bottle goes to waste once it’s been opened. Join us for Esculent’s third episode with special guest and Director of Beverage and Culture, Sergio del Castillo and co-chef Saqib Keval, as they describe the restaurant’s cocktail program and the ethics that goes into its creation. With knowledgeable descriptions and different processes that go into making each spirit on the menu, guests are invited to taste for themselves, encountering new flavors and ingredients to learn how they’re made, and how those intimate tastes grow in relation to spirits.

When mezcal evokes memories of mom’s kitchen or relatives spritzing the spirit to the earth, it becomes clear that smoke has never been adequate to describe a taste of mezcal. In Esculent’s next episode, we are joined by Mi Oaxaca’s founder, Fabiola Santiago, as we take a look at the different ways people encounter mezcal — either through tasting wheels, aromas, or the memories and relations we ascribe to the beverage. How can we fill in the gaps from tasting wheels that enforce Eurocentric aromas? Together, we think about how one can “taste” mezcal in ways that create relations, rather than orchestrate erasure.

When studying the history of mezcal, why begin with the milky, lightly fermented beverage pulque? In Esculent’s new season, we are joined once again by Professor Daniela Gutiérrez Flores as we navigate the archives detailing the cultural significance of the maguey plant in Mesoamerica. From discussing pulque’s role in sacred ritual to examining the colonial context of mezcal–both from maguey– we begin to center the narrative on Indigenous practices and experiences.

This season welcomes co-host Daniela Gutiérrez Flores as we prepare to travel with Fabiola Santiago and the organization Mi Oaxaca -- we are honored to be thinking, sensing, and traveling with care over the next episodes, all about mezcal.

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.

Tasting: J. Street Chocolate with Shared Cultures’ cacao-nib miso (featuring koji culture)

Host: Professor Elizabeth McQueen & Professor Charlotte Biltekoff

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.

Tasting: TCHO “Napa Noir” dark chocolate with cacao nibs, aged in red wine barrels and infused with cabernet sauvignon sea salt from Clif Family Winery

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.

Tasting: Bouchard Probiotic Dark Belgian Chocolate (72%), infused with Bifidobacterium longum

How do we understand taste as something measurable and communicable? Distinguished Professor Hildegarde Heymann joins Esculent to explore the field of sensory science, a discipline that transforms fleeting sensory impressions into data and descriptive language. From wine and spirits to chocolate and ice cream, Professor Heymann’s work has shaped how sensory researchers structure panels, train tasters, and translate perception into scientific method.

In this episode, we take up the connection between sensory science and esculence: how the languages and systems used to evaluate flavor also participate in producing edibility itself.

What does it mean to taste in context? Professor Julien Delarue joins Esculent to discuss his research on immersive sensory environments and how surroundings—visual, auditory, spatial—shape our perception of flavor. From reproducing a Korean street market in the lab to considering atmosphere in sensory evaluation, Professor Delarue’s work asks us to reconsider context not as background but as a fundamental component of the sensory experience.

Tasting: Dandelion Semuliki Forest 70% chocolate, processed in both San Francisco and Tokyo

What does it mean to study taste, edibility, and food systems through the scientific method? In our season introduction, co-hosts Professor Charlotte Biltekoff (American Studies & Food Science and Technology, UC Davis) and Professor Elizabeth McQueen (College of Fine Arts, FSU) set the stage for a season centered on food scientists — their methods, their imaginaries, and technological and microscopic infrastructures that construct another thread of the esculent.

Together, they reflect on the convergence of cultural inquiry and scientific practice, the recent history of sensory analysis, and how these approaches craft a dominant imaginary, but imagined nonetheless, of taste.
