JC Jacobsen founded his first brewery on a hill in the village of Valby near Copenhagen and he called it Carlsberg after Carl, his five year old son and the Danish word for hill - berg. JC Jacobsen introduced new standards of production to the Danish market and his new beer was an instant success. As Carlsberg became more successful JC Jacobsen ensured that his son was trained to follow in his footsteps and in 1870 he founded an independent brewery adjacent to his own site for Carl. Following a disagreement with his father Carl Jacobsen later established a brewery of his own. In 1881 Ny Carlsberg (New Carlsberg) was inaugurated and Carlsberg is brewed on the same site to this day.
