This article explains how to set up a double-blind cupping session.
Setting up a double-blind cupping session is available for the following products:
- Lab
- Roast: Professional and higher tiers
- Commerce
The setup of a double-blind cupping session consists of two phases and requires two people - further referred to as Person A and Person B.
Phase 1: Outside of Cropster (Person A)
Before setting up the actual session within Cropster, Person A has to conduct the following steps:
- Select the samples to be cupped and put the samples on the cupping table.
- Label each sample with the related ID-tag (e.g. PR-XXXX, PB-XXXX, SG-XXXX...) only.
The label must show the ID-tag only. - Then Person A must leave the room and Person B takes over.
What is an ID-Tag?
Cropster automatically assigns ID-tags for every green lot, roast lot, sample and blend. ID-tags are required to provide internal traceability across the processes within our system and for this reason, cannot be changed.
Where do I get the lot ID-tag from?
- Ask your roaster for the ID-tag.
- Look it up within the Roasts or Samples overview pages.
Phase 2: Setting up the session in Cropster (Person B)
Now that Person B has taken over, they have to conduct the following steps:
- Login to the online platform C-sar.
- Navigate to Quality > Sessions.
- Click Create Cupping Session.
- Select Double-blind Cupping.
- Enter a name for your session, schedule a time, choose a cupping sheet and the type of the labels.
- Add the samples, by searching for the ID-tag.
In the double-blind cupping mode, Cropster shows only the ID-tag without a lot name.
💡 You need to enter the full ID-tag. - When done, click Save & Next.
- Cropster now shows you which ID-tag is attached to which sample code. Replace the ID-tag labels accordingly with the sample code labels.
- Now, the samples on the cupping table must only be marked with the sample code, e.g. A, B, C,...
