The Modern Bar Cart Podcast

In part two of my exploration of flavor and memory with Dr. Kevin Peterson, some of the topics we discuss include:
What the Big 5 personality index (also known as OCEAN) might be able to teach us about how guests think about factors like novelty and comfort in the cocktails they enjoy.

The difference between the highest-rated drink (on average) on most Castalia menus, versus the highest-rated drinks for specific individuals.

How people respond when asked to describe their ideal cocktail - including the aesthetics and memories they tended to focus on, and which qualities they most often left out of the description.

We also explore a somewhat half-baked theory I propose about flavor as an "attractor," which is an explanatory concept taken from complex systems science that deals with nonlinear dynamics.

Along the way, we muse on the complexities of serving baijiu cocktails in the midwest, what kinds of cocktail experiments Dr. Peterson would run if we were all guinea pigs in his flavor lab, the sublime transcendence of cauliflower and pomegranate marinated lamb, and much, much more.


Please head over to sfumatofragrances.com to check out Cocktail Theory and pre-order his upcoming book, Data-Driven Drinks, and I hope you enjoy the thrilling conclusion of my latest interview with Dr. Kevin Peterson.

In this data-driven conversation with Dr. Kevin Peterson, some of the topics we discuss include:
How winding down Castalia and Sfumato after a decade of service provided the impetus for this new project, and why Kevin has set out to address a very different set of questions than in his last book, Cocktail Theory.

Why matching a person with their ideal drink is very different (and much more difficult, it turns out) from trying to make the optimal Old Fashioned or Negroni or Daiquiri.

This leads to a conversation about all the variables that go into cocktail preference: sweetness, acidity, bitterness, booziness, effervescence, egg white, spiciness, and so much more - how does one begin to build such a high-dimensional beverage algorithm in pursuit of aesthetic pleasure?

We also discuss some of the algorithmic tests that good bar programs and bartenders can implement in order to zero in on guest preferences more quickly. These include good menu writing, the classic bartender's choice speed interview, and the possibility for creating a guest profile with likes and dislikes.

Along the way, we explore why spicy drinks are a trap, the sea change I experienced the first time I tasted Green Chartreuse, the idea of perceptual thresholds in cocktails and in life, and much, much more.

In this fascinating conversation with Max Well and Alex Lamb, directors of The Donn of Tiki, some of the topics we discuss include:
How a COVID-era YouTube short on the history of Tiki in LA snowballed into a full-length feature film on one of the most iconic bar entrepreneurs of the 20th century: Ernest Gantt, AKA Donn Beach, AKA "Don the Beachcomber."

The way that stop-motion puppetry and clever era-appropriate animations were used to give Donn an embodied presence in his own story, with audio unearthed from a single set of tapes uncovered at the University of Hawaii.

The interesting ironies that run through Donn's life, including his propensity to build big and lose everything and the very different love interests who came and went, changing his trajectory and altering the arc of tropical drinks history in the process.

We also explore the two seemingly opposed natures operating at the same time in Donn Beach: his unwavering pursuit of authenticity and quality, on the one hand, which was often masked by his flair for showmanship and his trickster-like talent for tall tales and misdirection.

Along the way, we revel in Donn's ability to create freak evening thunderstorms with a hose atop his LA speakeasy, speculate about how he might feel about super juice, and even take the time to appreciate his unexpected role in the revival of authentic Hawaiian culture in the 20th century.


When this episode airs, Alex and Max will still be touring and doing screenings around the country, so head over to TheDonnOfTiki.com to check out their schedule, and be sure to keep your eyes peeled for when this film hits your favorite streaming services in the near future.

Eric kicks off 2026 with an audio essay rant targeted at the ham-fisted "percentage" math that people use to answer the question:
"How much of a whiskey's flavor comes from the barrel?"
In the censored words of George Carlin: "It's all BS, and it's bad for ya." To demonstrate this, we sift through GC-MS whiskey sample results, human neurobiology, and behavioral economics.
In the end, it's a poorly posed question invented to solve a problem that doesn't exist, and it colors our expectations about flavor in harmful ways.

This time around, we'll be taking a look at drinking rituals from around the world.
A few months back, my friend Reece Sims asked me to write an article about drinking rituals for her new publication, The Flavour Report. She has graciously agreed to let me read the article on-air and give you all a bit of a "Director's Cut" version of the article, entitled: Sacred Serves: The Rituals That Make Drinking Human.
For those of you who have the opportunity to enjoy a few drinks with family and friends this holiday season, I hope some of these thoughts about the importance of ritual, hospitality, gratitude, and the sometimes radical act of coming together can help you to appreciate some of those moments even more.
Please remember, as always, to drink responsibly and experiment boldly.
