In the Russian Empire, confectionery products were first produced using steam machines. In 1900, the construction of a three-story building adjacent to the southern side of the Ramon sugar factory was completed. Here was located the "Ramon Steam Candy and Chocolate Factory of Her Imperial Highness Princess Evgenia Maximilianovna of Oldenburg." Experienced confectioners in pristine white uniforms arrived from the capitals to work at the factory. The auxiliary staff consisted of local peasants and teenagers, as well as residents of nearby villages.

Production quickly expanded, and the factory's assortment included chocolate "Sport," "Children's," "Rowan," "Health," marmalade "Imperial," candies with names like "Grenadine," "Guava," "Mango," "Russian Heroes," and other sweets. According to the 1908 price list, the assortment included over 400 items.

Fruits from the Bunin estate and those purchased from local residents were used to make marmalade and fillings. Anna Yefimovna Puchkova, who worked at the factory as a child, recounted that one of the fillings was made from watermelon rinds. The watermelon flesh was not used, and local residents awaited its distribution, while the rinds were turned into candied fruits.

The factory's products were beautifully packaged. The wrappers and foils were bright and glossy, created to a high artistic standard. Labels depicted charming ladies or the factory building. Some residents mistakenly took them for images of Catherine I, Catherine II, or Princess Evgenia herself.

The wrappers were likely developed in the artistic-industrial workshops of Princess Oldenburg. For local peasants, they were a novelty, and many kept them, decorating their chests.

The products were shipped to Moscow and St. Petersburg. On plywood boxes, it was marked: "Ramon. Voronezh Province. Dept. St. Petersburg, Main warehouse, Moscow." Metal boxes were used for packaging bonbons. Local residents could buy candies and gingerbread in shops.

Ramon sweets quickly gained recognition in Russia and abroad. In 1903, they received a gold medal at an exhibition in London, and in 1904, silver and bronze medals in Brussels and Paris. The factory also received the Grand Prix.

However, the factory did not last long. The revolutionary events of 1905 and 1907 destabilized its operations. Workers began strikes, and a fire in 1905 destroyed the finished goods warehouse. In 1908, the Oldenburgs left Ramon, and the estate passed to the Department of Estates. A struggle for ownership of the factory began, involving companies such as Eidem and Abrikosov. In 1911, the factory was closed and sold in Voronezh along with its equipment. For some time, candies were produced in the wrappers of the Ramon factory.
