In this episode we will discuss roasting related topics with Gwilym Davies. We start with our take on dark roasts, and after that Gwilym will reveal some cool insights into how he assesses lighter roasts for espresso by testing the solubility of coffee.

We will also touch on problems with consistency during roasting. Gwilym thinks the problem is caused by the nature of the coffee roasters, which are notoricaly temperature unstable. I take a slightly different approach: I see the problem in the nature of the always-changing ingredient – coffee. We agree that we have to recognize this issue and we have to work with it in mind.
What if a coffee roaster ruins a batch? We’ll give you a few tips on what to do with coffee that is not up to your standards.
