Giesen roasters are manufactured in Holland, close to the border with Germany. The company was established in the late 1990’s and Giesen has been producing its own brand of coffee roasters since 2007. The design of Giesen roasters is based on the traditional approach of German roaster manufacturers, using high end materials (like cast iron) and super-efficient burners and sophisticated controls for the benefit of optimizing flavor profiles.
Giesen roasting machines are equipped with powerful precision burners and high velocity, controllable fans which create the unique benefit of rapid response roasting, which puts the roast master under almost any circumstance in total control of the roasting process. Unlike most other machine brands, Giesen roasters allow the operator to manipulate the Rate of Rise (RoR) at any point in the roast cycle.
Giesen machines are designed to apply relatively high levels of convection heat which benefits the sweetness of the acidity and the intensity of aromatics. The roasters are designed to use clean, fresh air, which accentuates the integrity of natural coffee flavors.
