    1. ALL of the information you are asking for is available on this forum.
    2. Watch ALL Mill City Roaster video classes on roasting.
    Q: How did you get a 15k roaster and NOT know how to roast???
    Option: If you offer to cover expenses I'm sure someone would be willing teach you the fine art of roasting.
