And, had Mark Davies brought his goal kicking boots with him, the scoreboard could have been further in the favour of the visitors.
However, Bristol edged back in front in first half injury time through an Ed Barnes penalty and Gloucester were never quite back on terms.
However, the real breaking point came in the opening minutes of the second period when captain Ejike Uzoijwe was sinbinned and Bristol took full advantage of their numerical superiority to run in two tries in his absence.
Bristol then started to turn the screw and were able to introduce international players from the bench in the form of Kevin Maggs and Graeme Beveridge.
The young Gloucester team found the going increasingly tough up front and were shoved back over their own line for the fourth Bristol score from a catch and drive.
Soon afterwards referee Bruce Robertson determined that a fog that had descended during the first half and was steadily growing thicker had rendered conditions unplayable and called an end to proceedings with Bristol ahead 29-8.
