Roastmaster Brian is seeking ultimate control while roasting coffee for the DoubleShot. After fighting with an improper power burner for well over a year, Joerg Bollgen stepped in to save the day. Joerg is the owner of Intelligent Combustion Control Technology, and previously worked as a factory technician at Weishaupt Corp. in Germany, the manufacturer of the new DoubleShot roaster burner. Joerg talks about the difference between the old and new burner, as well as the seemingly-limitless applications a good modulating burner can be used for.
