Summary of Caravela QC process we witnessed 29/30 Apr

While traveling with Caravela we were fortunate to get an insiders view into the Quality Control assessment they do, for coffees to be selected by them. What follow  is what we witnessed at Gigante, near the home of Edilfonso Yara and Jaimie Casallas. We then did the process ourselves in Pitalito near San Augstin. Farmers bring the bags of parchment it is weighed. Then they take a sample, that silver lance Salome is holding is how they get the sample from the bag. They use a cross section sample.

They then de-partch 300g to calc yield.

  1.  First they measure:
  2. Then they remove parchment.
  3. They then calculate the weight loss from parchment.
    The result of the loss must be less than 20%, otherwise it fails the quality control.
  4. Then they screen sort. Either with a manual sorter or an automatic one. Seperated into screen 15+; Screen 13/14 and reflects which are sorted into group 1, (if only one bean of that group is in a coffee it will affect the cup), and group 2 ( 10 beans will affect the cup. 
  5. Then they manually remove damaged coffee from broca etc. They then weight each component after separating And calc percentage reject if above maximum broca 1.5%, AA as AAA 1% etc The do moisture test, it must be must be 11%.  
  6. Then they test water activity should be about 0.6 which tests the internal humidity. 
  7. Then they roast and cup in the afternoon. Then score and reject or accept. And the form is saved and feedback is given to the farmer / producer. img_0760-1The one above had no cupping score since it was rejected before roasting.
