Coffee Roasting, Part 2: Roasting made e...

JAMES HARPER
About this episode
Roasting coffee can be maddening. Just 4° Celsius is enough to make the same green beans taste distinctly different! And there are so many things roasters can play around with: temperature, time, fan speed, drum speed, types of probes…the list goes on and on.

So, if you want to start roasting yourself, where do you start!?

In the first half of this episode, I interview one of the world's leading roasting teachers who takes me through his published scientific research to give a clear answer. It’s as simple as 80%, 15% and 5%.

And then, in the second half, I show you why roasting coffee consistently batch-after-batch is so difficult. But these problems are finally being solved with smart technologies.

I visited the ROEST engineering team in Oslo and cracked open their innovative prototype P3000 roaster to show you the technology that allows anybody to roast coffee consistently and fully automatically.

I am so impressed with these innovations, I believe they’re going to change the coffee industry.

Why one Colombian farmer chose specialty, and the other walked away
I travel to Colombia’s Huila region to answer a question that’s puzzled me for years: if specialty coffee pays more, is better for the environment, and brews tastier cups—why don’t more farmers grow it? I speak with two producers in the same region whose choices couldn’t be more ... Show More
