Coffee Roasting Navigated

Therese Brøndsted

A podcast for coffee roasters. This is NOT an introduction to start roasting coffee, but for people who already roast coffee.

It's about all the different ways of doing it. The coffee roasting process is very complex. The taste is affected by so many things. It's difficult to control completely. Different roasters use different ways to control the process: the time, the color, the smell, the bean temperature - and the possibilities are increasing with new technology.

Made by Therese Brøndsted from Denmark. She has a Master degree in Food Science and Sensory evaluation. She has been roasting coffee since 2014.
