You say 'amateur home chocolate maker' so I think the Intensive Chocolate Workshop is more for you if you plan to keep it mostly as a hobby and want to learn new techniques. I believe the production class is more about shelf life and scaling up as a business, though I haven't taken it.
Is 'that next step' upping your bonbon game with more colors and layers and new toys, or growing a part-time business into full time with a commercial kitchen and wholesale accounts?
