RDT- Does it make coffee better? (Exploring the Hendon study with Timemore Sculptor 078S)​⁠​⁠​⁠ ​⁠

This video discusses the recent study by Professor Hendon titled “Moisture-controlled triboelectrification during coffee grinding”. I have discussed the most interesting part of the study which is about the effects of RDT on coffee charge and extraction. I have also discussed the surprising results of my experiments with RDT using the 078S grinder. Edit: At 25:51, the visual should read "Less water and leaving the beans soaked till the water is absorbed, both increase the speed of extraction". The study can be found at https://doi.org/10.1016/j.matt.2023.1... 00:00 Introduction 01:05 What is triboelectrification? 03:14 Fractoelectrification 03:36 Introduction to study, what is correlation 05:38 Roast colour and Charge 07:06 Water content and Charge 08:10 Particle size distribution of charged particles 10:46 What happens to charge if you grind finer? 12:16 Effect of RDT on charge and extraction time 15:31 Coffee experiments 16:20 Medium dark roast 18:40 Medium roast 20:52 Light roast 24:52 Conclusions #rdt #espresso #timemore #sculptor 078S #coffee #barista #triboelectrification #ross droplet technique
