Coffee Lit. Rev.

Chris and Doran are joined by Prof. Nicola Segata from University of Trento. Prof. Segata is a world famous professor of computational metagenomics, and is the senior author on a recently published study that strongly suggests that consuming coffee directly affects the population of some gut bacteria. Metagenomics is far removed from our expertise. Instead of us fumbling around the paper, we decided to have the true world expert come talk to us about it. Production note: The paper came out over the holiday period so we recorded remotely. The sound quality is not what we usually strive for, but the content quality is exceptionally high. We hope you enjoy. The paper: Nat. Microbio., 2024, 9, 3120 https://doi.org/10.1038/s41564-024-01858-9 The article can be found in coffee literature library: ⁠⁠https://pages.uoregon.edu/chendon/coffee_literature/coffee_lit_rev/⁠⁠ About Nicola Segata: Prof. Segata is from Trento, matriculated through Trento, spent a brief period as a postdoc at Harvard, and returned to Trento where he holds a position as Professor of Computational Metagenomics. He is one of the most highly cited scientists in all fields and has a staggering career of papers that merge computational biology with amazing experimental datasets. You can find his other works here. Introduction preamble: Friends.

Chris and Doran are joined by Tonx (Tony Konecny) from YES PLZ from Los Angeles, CA. We discuss a paper from the Yeretzian lab out of ZHAW. The paper aims to address a common question for the home coffee consumer, "How should you store your coffee one the bag is open?". We immediately thought of Tonx and YES PLZ, who have experimented with various packages for their subscription service. We hope you enjoy the episode. The paper: Food Packag. Shelf Life, 2022, 33, 100893. https://doi.org/10.1016/j.fpsl.2022.100893 The article can be found in coffee literature library: ⁠https://pages.uoregon.edu/chendon/coffee_literature/coffee_lit_rev/⁠. About Tonx: Legend of subscription coffee, Tonx started Tonx coffee and later a coffee/restaurant venture called LocoL. Pre-pandemic he rolled out his current subscription service, YES PLZ. Good timing — home coffee consumption exploded during the 2020-2021 years. Introduction preamble: Steve Leighton

Chris and Doran are joined by David Yardley from Moongoat Coffee out of Costa Mesa, CA to discuss a series of papers discussing the emergence of mold in coffee. Mold is bad. Ochratoxin A is bad. But how much of it is there, and how bad does it have to get? The three papers: Food Sci. Biotechnol., 2018, 27, 891. J. Agric. Food Chem., 1998, 46, 673. Food Chem. Toxicol., 1995, 5, 341. The article can be found in coffee literature library: https://pages.uoregon.edu/chendon/coffee_literature/coffee_lit_rev/. About David: Coming up from the entry level job at Starbucks, David is now the leader of Moongoat coffee, a roastery and series of cafes in the southern Californian region. Introduction preamble: Don Pettit

Chris and Doran are joined by Alex Kaplan from Cometeer to discuss an old school paper titled, "An investigation into the relationship between freezing rate and mean ice crystal size for coffee extracts", appearing in Trans. IChemE, 2002, 80, 176. The paper is part of a conference proceeding which was published in the journal Food Bioprod. Process. This paper looks at how freezing rate determines the ice crystal size. The paper itself is really about developing a model that correctly captures how brewed coffee freezes, but we used it as a platform to understand how coffee behaves when cooled. The article can be found here: https://doi.org/10.1205/096030802760309197 About Alex: We couldn't have had a better guest, as Alex is the Head of Coffee Product for Cometeer, a company that manufactures frozen coffee extracts. Alex also has a degree in physics from Princeton, is a Q-grader, and was a pleasure getting nerdy with. Introduction preamble: George Clooney
