These are my notes on using various Kaffelogic roasting profiles, specifically targeting nordic style roasts.

J-Roast v7

• In Profile settings, use:
  • 80g for Natural
  • 90g for Washed/anerobics
• With the Chaff collector installed, use Fan preview to make sure there is enough agitation.
  • Agitation should look similar to the video found on this page: https://kaffelogic.atlassian.net/servicedesk/customer/portal/1/article/11730945?src=-2107542245
  • Start at a number that matches the reference load of the profile (120g coffee, 120g boost setting)
  • If there is too much agitation, do ONE of the following:

    • Decrease the boost load setting (120g ⇒ 110g)

                                           OR
      

    • Increase the charge size (120g ⇒ 130g of beans)

  • If there is too little agitation, do ONE of the following:

    • Increase the boost load setting (120g ⇒ 130g)

                                        OR
      

    • Decrease the charge size (120g ⇒ 110g beans)

The goal is to have a power line that starts lower and then steps up, then finally is relatively flat until the end of the roast.

An ideal chart will look similar to the following one:

Troubleshooting

• If your power flatlines during the roast as in the chart below, try adding more beans to the charge (start with 10g).
