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.

Chris and Doran are joined by Kathie Hilberg and Bronwen Serna from the Totally Dissolved Podcast to discuss the papers that led to the development of the 2016 SCA flavor wheel.
The wheel is basically the artistic manifestation of two peer-reviewed papers, "Development of a “living” lexicon for descriptive sensory analysis of brewed coffee", appearing in J. Sens. Stud., 2016, 31, 465
and
"Using Single Free Sorting and Multivariate Exploratory Methods to Design a New Coffee Taster’s Flavor Wheel", appearing in J. Food Sci., 2016, 81, S2997.
The lexicon developed in the first paper may be accessed through World Coffee Research.
