    In this episode we talk with (soon to be Dr.) Laudia Anokye‑Bempah and Dr. Irwin R. Donis‑González from the UC Davis coffee center about their recent paper on how roast profile impacts available extractable acids in coffee. The paper was published in Sci.

    Ep24. Novel coffee foods in the EU with Dr. Dirk Lachenmeier

    In this episode, we meet with Dr. Dirk Lachenmeier, head of the department of plant-based foods at CVUA Karlsruhe and expert in coffee, weed, and booze. We discuss a paper that reviews which parts of the coffee plant have approval for use as food in the European Union. Everything from the leaves of the plant to the silver skin. Can you really make money off these by-products? The paper is open access: Lachenmeier, Rajcic de Rezende, and Schwarz "An Update on Sustainable Valorization of Coffee By-Products as Novel Foods within the European Union" Biol. Life Sci.

    Ep23. Better pour over with Dr. Arnold Mathijssen (U. Penn.)

    In this episode, we meet with Dr. Arnold Mathijssen, Assistant Professor of Physics at U. Penn., and author of a paper recently published in Physics of Fluids, "Pour-over coffee: Mixing by a water jet impinging on a granular bed with avalanche dynamics". This paper just did the mainstream media rounds, so you may have heard about its findings on some other outlet. In this podcast we break it down and figure out whether physicists at U. Penn. revolutionized pour over. The paper can be found here and is also available in the CLR library (link on instagram, @coffeelitrev). Introduction featuring James Hoffmann.

    Ep22. Chlorogenic acid and end-of-year awards with Dr. Alex Murray and Prof. Carl Brozek

    Chris is joined by Dr. Alex Murray to discuss chlorogenic acid. We talk about how plants make it, what it does, what it tastes like, and how we might make it. We discuss a variety of papers, book chapter, and so forth. Check the library link on instagram for some of them. Then, Alex and Chris spend some time on the year-end awards. End of year awards: 23:52 Libation prize. 28:57 Spurlock award. 32:35 MTG tool of the year. 36:10 Fruit of the year. 39:49 Beast of the year. 45:03 Then, we shift to discussing movies of 2024 with Prof. Carl Brozek. Did anything released this year compete with Prof. Brozek or Chris' top three movies of all time? About Dr. Alex Murray: He is from Hull, UK, and received his PhD from Bath. After a brief postdoc at MIT, followed by a professorship at Kent, he joined a startup Boston-based startup, Daqus. They specialize in creating novel battery materials. Chris and Alex lived together during their PhDs. and have been doing annual awards for a long time, but its the first time we put it on record. About Prof. Carl Brozek: Prof. Brozek leads a materials chemistry research group at the University of Oregon. He is from Chicago, with a PhD at MIT and postdoc at Washington. Chris and Carl collaborate a lot. Introduction preamble: Airplane 2.

    Ep21. The value of latte art with Emilee Bryant

    Chris and Doran are joined by Emilee Bryant to discuss a pair of papers that probe whether latte art a) is perceived as more valuable and b) affects the perceived flavor of the drink. Ordering a cappuccino is delightful. But is it more delightful with a rosetta? Would you be somehow compelled to pay more for it if it had one? Does it taste sweeter? The papers are: J. Sens. Stud., 2015, 30, 305 https://doi.org/10.1111/joss.12159 Br. Food J., 2021, 123⁠, 1931 https://doi.org/10.1108/BFJ-07-2020-0612 About Emilee: Originally from Houston, Emilee moved to live in a hippie tree house before finding her way to Brooklyn where she lives now. She is a latte art champion, YouTube content creator, and film maker. Check her out on instagram (emstagrim), and YouTube (EmileeBryant). Introduction preamble: Lorelai Gilmore and Luke Danes

    12/16/2024

    Ep20. Do light or dark roasts have more caffeine?

    In this episode Chris and Doran discuss the age-old question of whether dark or light roast brewed coffees have more caffeine. The discussion was inspired by a paper published recently in Scientific Reports titled, "Caffeine content in filter coffee brews as a function of degree of roast and extraction yield". So, do light and dark roast coffee extracts have different caffeine concentrations? The paper is open access and available from the publisher: Sci. Rep., 2024, 14, 29126 https://doi.org/10.1038/s41598-024-80385-3 Introduction preamble: Captain Janeway.

    Ep19. Microplastics in coffee with Alex Dainis

    Chris and Doran are joined by Dr. Alex Dainis, a professional science communicator. We first met Alex through her work on "Chemistry Shorts", videos about sub-disciplines of chemistry supported by the Dreyfus foundation. Today's paper is about microplastics. These are microscopic pieces of polymer that show up everywhere. In the case in single-serve coffee preparations. Alex is the perfect guest to discuss this because its a topic that is becoming increasingly studied, but to date we simply don't know all that much about whether they are bad for you. We get into that and much, much more. I hope you enjoy! The paper: Pouring hot water through drip bags releases thousands of microplastics into coffee Food Chem., 2023, 415, 135717 ⁠https://doi.org/10.1016/j.foodchem.2023.135717 The article can be found in coffee literature library: ⁠⁠⁠https://pages.uoregon.edu/chendon/coffee_literature/coffee_lit_rev/⁠⁠⁠ About Dr. Dainis: Blimp lover. She has a PhD in genetics from Stanford but is also trained in film and television. After she finished her PhD she founded Helicase media while also being a professional science communicator. Introduction preamble: Pulp Fiction.
