Lower grown coffee, identifying a roast profile

We woke up to snow

When we woke up this morning it had been snowing, we took a quick drive to get a view of the lake before going back to Diedrich to work on perfecting roasting profiles for the new coffee Java Kopi, from Sumatra, which is a lower grown coffee, and hence requires a different profile, which we needed to identify.

Frog Quaffer was happier with the profiles that we were able to produce. There was a lot of coffee roasted during the day, all collected and Frog Quaffer posed with it:

Even though these where just sample roasts there was quite a lot of chaff that collected in the 5kg IR coffee roaster.

It over filled a bucket as seen here with Steve and Mzukisi

We essentially created 4 profiles:
  1. Where there is a quick elevation in temperature initially, then a gentle increase
  2. Where there is a slow elevation in temperature initially and a gentle increase
  3. Where the elevation is consistent
  4. Where there is a quick elevation in temperature, then a gentle and then a quick increase.
Tomorrow we will cup the results, and work with airflow, something that Diedrich inovated in coffee roasting.
