Tested.
Coffee is full of claims. Socratic Coffee tests them.
Independent, self-funded research into coffee gear and technique.
We find a falsifiable claim, design a controlled experiment around it, and publish the method and the data, including the times the claim holds up.
2015
The year we set out to find objective truths about coffee.
STUDIES
Objective testing, never subjective assessment. Every study comes with its data, the details of how it was run, and the analysis, all free. How you interpret or use it is up to you. Our goal is simply clean, transparent, objective data.
