- Explanation of the three roast phases
- Why does air flow and load affect the temperature of the phase changes
- How does energy at the start affect development at the end
Our schedule has been disrupted during the week 25-29 May. During this week we have been concentrating on coaching participants with profiles they are creating. We have also had some technical issues with recording sessions, so we have moved this week's topics into next week to ensure they are captured. Here is a recording of Wednesday's tutorial https://vimeo.com/423364483 and Thursday's https://vimeo.com/426070112
