Horizontally cylindrical gas coffee roaster, placed on a metal four-legged stand has a roasting box with a small handwheel on one side. Before gas roasting, people often roast on a charcoal stove. Charcoal roasting is a unique method of roasting coffee beans in a specialty store. With the charcoal, coffee beans are ripened deep inside thanks to a much larger impact than infrared heating, so they become soft, smooth and fragrant. Later, orthodox coffee roasting in Europe used gas burners. Due to the skillfull requirements of roasting and the difficulty of finding a steady source of charcoal, there are very few shops that offer charcoal roasted coffee. Stores in Europe, especially in Germany, are also striving for the ideal flavor and charcoal roasting method. This roaster was bought by the Germans from an exclusive product of Ethiopia in the 1880s. Until 1920, the German country produced roasters almost like this one because this manual roasting helps Arabica coffee beans become stable in color and their taste after brewing is also relatively strong and mild in aroma. Today with modern technology around the world, it is very difficult to find the similar roasters, because there is no place to produce them anymore except that you can see them in Museums.
