How to create a pre-roast blend

This article shows you how to roast a pre-roast blend using Cropster. 

Creating a pre-roast blend consists of two steps: 

Creating a Pre-roast blend profile

  1. Log in to the online platform C-sar
  2. Go to the Profiles overview page by clicking on Roasts > Profiles
  3. To create a new profile, click the + Create Profile button in the upper right corner. 
  4. Choose Pre-roast blend and enter the following information:
    • Profile name*: Give your profile a name
    • Associated profile group**: Select a Profile group to link the new profile.
      Note: This can be done later on from the Profile groups page. 
    • Roast batch naming*: Choose how you want to name the roasted batches
    • Reference roast: Select a reference roast (remember this will be the grey curve in the background of your Roasting Intelligence that guides you through the roast). If there is no reference yet, you can choose one later.
    • Expected weight loss: Enter the expected weight loss. If you leave this field empty, Cropster will take the average weight loss after 10 roasts.

    • Machine: Enter the ideal batch size and restrict your profile to a certain machine (optional)
    • Goals**: Exclude profile from global roasting goals (optional)
    • Add project: Assign your profile to a certain project (optional)
