Using Classifications

This article will provide an overview of Classifications, detailing the process for creating and viewing them within the online platform C-sar.




What are the Classifications?


Classifications serve to categorize coffees based on their quality characteristics, with a particular emphasis on screen size.

This categorization is essential for estimating the expected green weight of coffee before the dry-milling process takes place.

  1. Log in to the online platform C-sar.
  2. Navigate to Quality on the main menu bar and select Classifications
  3. Click +Add new classification to create new Classifications.

  3. Add Notes (optional).
  4. Click the Create classification button to submit. 

Selecting a standard classification from the list 

Standard classifications provide a foundational framework but can be tailored to meet specific needs and preferences.


The standard classifications consist of a curated list of criteria derived from the Classification systems used in various countries.

  1. To create classifications based on these established standards, simply locate and select the country of origin from the provided list.

  2. Enter and/or select the following details:
    * is indicating mandatory fields.
    • *Name
    • Processing method
    • Varieties
    • Estimated yield
      ❗This detail is available only for Origin.  
      • Enabled
        • *Default yield factor (%):  Enter a percentage that you would usually expect to receive for this classification. 
          💡For instance, if you typically obtain 50 kg of green coffee from milling 100 kg of parchment for Colombia Excelso 15, you should input 50% as the default yield factor.
      • Disabled - Recommended for defects.
  3. Activate the toggle by switching it to green to access additional details:
    💡 You have the option to further refine each detail based on various criteria.

    • Add Notes (optional) to further describe the classification.
    • Click the Create classification button to submit. 


      If you do not specify any criteria for the Processing method, this classification will apply to all lots.

      If you define specific criteria, any lot that meets at least one of the selected processing methods or varieties will qualify for this classification.

      Enabling screen size standards

      Activate the "Enable screen size standards" toggle by switching it to green.

      • The range runs from 10 to 20, and you can adjust the slider to define the specific range applicable to this classification.
      • If you choose the option to "Use peaberry screen sizes instead of flat beans" by clicking on the respective checkbox, the screen size range will adjust to between 8 and 13, which corresponds to the dimensions of the oblong-shaped peaberry screens.

      • You can establish a tolerance for the percentage weight of beans that falls outside the target range. By default, the lower limit of this allowed range is designated as "UG" (Under Grade), while the upper limit is set at 20, which represents the largest screen size available.
      • If you choose the option to "Restrict screen size range beyond target" by clicking on the respective checkbox, you can further restrict the Allowed range minimum and maximum.

      • Defects 1 max: Enter the maximum number of primary (Category 1) defects allowed for this classification.
      • Defects 2 max: Enter the minimum number of primary (Category 2) defects allowed for this classification.
      • Total defects max: Enter the maximum number of total defect equivalents (Category 1 + Category 2) allowed for this classification.

      Enabling sensorial standards

      Activate the "Enable sensorial standards" toggle by switching it to green.

      4. In this section, you will find several columns displaying key information:
        • Classification name: Only classifications that meet the specified filter criteria and have the estimation option activated will be displayed.
        • Yield factor (%): At first, the default yield factor will be shown.
          💡This value will be updated if a green grading analysis utilizing advanced screen sizes is conducted.
        • Yield factor (kg/unit): The green weight unit, as specified in the Origin Settings, is divided by the Yield factor (%).
          💡This calculation is particularly prevalent in Colombia and indicates the number of kilograms required to produce a single unit, such as one 70 kg bag.
        • Est. green weight: The estimated green weight for this classification is calculated by multiplying the Yield Factor (%) by the current weight of the lot prior to milling.
