A beverage producing system includes a beverage producing machine and a jug. The machine is provided with a steam nozzle and the jug is provided with a steam duct having a steam inlet end configured to connect to the steam nozzle to establish a connection between the steam nozzle and the steam duct. The steam nozzle is housed in a recess having an entry aperture, a bottom wall and an upper ceiling. The steam nozzle is arranged at the bottom wall of the recess and is oriented towards the upper ceiling. The steam inlet end projects from the jug, where the connection between the steam nozzle and the steam duct is configured to be established by introducing the steam inlet end in the recess and by lowering the jug until a fluid connection is established between the steam nozzle and the steam inlet end of the steam duct.
