    Session status

    A Session has three stages:

    • Draft: In the draft stage, the session can be edited. You can add/remove samples, change the cupping sheet, etc.
    • Open: When a session is open, it's time to evaluate and submit results via Cropster Cup or directly within the online platform. Open session settings can not be altered. 
    • Closed: Indicates that a session is done and all results have been submitted. However, your results can be edited. If necessary, it is possible to reopen a session.


    Once a session is open, it is available in Cropster Cup. Every user of your account with Cropster Cup permissions can now evaluate the samples individually via the cupping app.
