At the end of the 19th century, with the arrival of Japanese migrants to Peru aboard the Sakura Maru, a young Japanese man left behind not only his land, but also his name. Seeking a new beginning, he settled in Rodríguez de Mendoza, where a family gave him their surname and he became known as Dionisio Portocarrero Arista. There, this entire story began, with coffee as the protagonist of his life.

Dionisio Portocarrero Arista, married to his best friend Clotilde Ocampo Guzmán, leave Rodríguez de Mendoza and migrate to San Martín with their 4 children, carrying coffee seeds and cebollón as a symbol of hope. They pass through Rioja, but hearing of better opportunities they continue to Moyobamba, where they settle, build their home and sow the beginning of their new life; their daughter Enma Portocarrero Ocampo, who arrives at 14, would continue the family coffee legacy.

Dionisio P.(1942) and Clotilde O.(1948) pass away, leaving Enma P.O., who makes coffee the family livelihood by selling it at the central market for 0.5 cents. In 1952 she becomes pregnant, unfortunately becoming a widow. She forms a new family and in 1958 her daughter, Reynalda Domínguez Portocarrero, is born, who would continue the legacy. At 11, Reynalda already sees how coffee sells for 30 cents; and at 14, after losing her father (1969) and mother (1972), she continues in sales, opening a new generation.

Alberto Prada Rodríguez, born in Lluyllucucha (1964), has been dedicated since 1975 to growing coffee, rice and more. He meets María Linarez Domínguez, whom he marries in 1990 and strengthens his work in the field. In 1992 they acquire their first truck to transport their products. Over time, Alberto steps away from coffee due to market volatility and lack of training, and recalls his grandfather Don Ricardo Linarez's phrase: 'To the farm I go, from the farm I come and nothing I have', this phrase inspires the birth of Grain and Grains: to teach, add value and recognize the farmer's effort.
