Coffee Science for CoffeePreneurs by CoffeeMind – Détails, épisodes et analyse

Welcome to this episode of Coffee Science for CoffeePreneurs! In today's episode, we delve into an essential concept that has been overlooked in our previous discussions on the theory of science, research design, and statistics— the "Evidence Hierarchy." I’m Morten Münchow, and I’m excited to explore how this model can transform our education systems and collaborations with research institutions in the specialty coffee business.

Highlights
Introduction to Evidence Hierarchy: Understand the relationship between expert experience, observation, and scientific scrutiny. Discover how applying this model correctly can revolutionize our approach to coffee education and research.
 
World of Coffee Seminars:
If you're attending the World of Coffee event in Copenhagen in June 2024, don't miss our free seminars in Room 6, Hall B. Topics include "How to Start a Roastery," "Cupping Form Confusion," "Rate of Rise Irrelevance," and "Improving Sensory Skills." If you can't make it in person, tune in to our live stream or catch the recorded sessions on our YouTube channel.
 
Expert Opinions vs. Scientific Research:
Learn why the current reliance on expert opinions in coffee education is problematic and how transitioning to a more evidence-based approach can benefit the community.

Case Studies and Research:
We discuss our own research, including the controversial topic of organic acids in coffee tasting and the Rate of Rise theory in roasting. Discover the gaps between anecdotal evidence and scientific validation and why it’s crucial to address these issues.

Challenges in Coffee Science:
Explore the barriers to collaboration between the specialty coffee business and universities, and how bureaucracy and politics hinder scientific progress in our community.

Call for Collaboration:
We invite educators and researchers to join us in a critical, open dialogue about the state of scientific methodology in the global coffee education community. Let's push for progress and refine our knowledge and practices.

By recognizing and applying the evidence hierarchy, we can better navigate the complex landscape of expert claims and scientific evidence, ultimately improving our educational systems and collaborative efforts in the coffee community. Join us in this insightful episode to become part of this transformative dialogue.

I metup with Andrew Stordy at their new office in London to see their new factory, plan our upcoming collaboration but primarily to sit down with Andrew and interview him about the IKAWA technology and business history.

Some calculations that shows the fundamental problems of using the SCA Cupping Form as an objective parameter estimate of 'quality'.

The term 'Subjectivity' is actually a bit problem when it comes to describing sensory methodology but it can be solved.

In this episode we will look deeper at Bayesianism which is the direction in research design handling the problem of verification and falsification is a really elegant model using probability theory. I'm explaining it using the example of a green coffee experiment.

In this episode I zoom in on Empiricism and Critical Rationalism which I consider the most useful foundation for the concept 'objectivity'

In this episode Occam's razor is introduced which is an important foundation for a good theory and examples of where this is not applied correctly is explained

In this episode we will go all the way back to Plato to discuss what a good theory looks like if it is to serve a community and not mislead
