Hottop is a high-quality, stable and well-designed roaster for the home. It is a drum roaster, meaning the beans are constantly moved in the drum to roast evenly. You can control the temperature inside the drum and you can regulate the air supply, thus influencing the roasting curve. By inserting the beans at the top of the roaster, you can pre-heat the device very precisely to the starting temperature, giving it a very accurate and consistent roast curve. In addition, the Hottop Roaster has a built-in cooling device, like the big commercial roasting machines. Cooling is essential to complete the roasting process at the time you want and at the exact roast you want. Through the window you can judge the beans very well with the eye, and both the first and the second crack are easy to hear.
