Recently I was asked by a fellow roaster how do I use colour tracker in the roastery and how important is it to have one to achieve consistency?
❌ If your curves are not perfectly aligned matching colour doesn't mean much. A 9 minute roast will taste different to a 10 minute roast even if they are the same colour.
✔ It is super useful when sample roasting
✔ I find its best use when transferring profiles from in my case 500g Mill City roaster to a production roast on a Giesen. Although worth mentioning curves look quite different in this case.
So in short it is a great tool but definitely not important as matching your profiles day to day 👌
