The Gloucester youngsters, ably coached by Peter Buxton, were reasonably comfortable winners in three of their games but were pushed hard in the final match - against local rivals Bath - before emerging triumphant.
The win was based very much on outstanding defence - only two tries in total were conceded in the four matches - with some huge hits being put in and some quality work at the breakdown creating numerous turnovers.
But Gloucester also had someone capable of conjuring up a scoring opportunity no matter who they fielded in the four games, with various players rising to the occasion and inspiring the team.
The first game, against Worcester, was notable for a hat trick from wing Alessandro Tiraboschi and also saw Ryan Kline score twice with Tyler Jerrum also crossing the whitewash.
Exeter had looked a big strong team in their win over Bristol but the Chiefs youngsters were visibly rocked by Gloucester's physicality in defence with wing Harry Howard leading the way.
Howard also scored a well taken try. Kline scored again with Ben Traas, Ollie Thorley and George Key also crossing. Only a late error led to an Exeter consolation.
Bristol, predictably, were well supported but still seemed to be outnumbered by the family members supporting the Gloucester boys!
The host team started brightly but couldn't cope with the pace and power of the Gloucester runners, fell off tackles and the Cherry and Whites took full advantage.
Elliot Creed and Morgan Bottrill both scored twice with Dan Scholey, Gareth Jones, Harry Howard and Toben Ronald completing the rout.
So, it call came down to the final game and Gloucester quickly found themselves in the unusual position of falling behind as Bath scored from distance.
Dogged defence kept Gloucester at bay until a couple of smart chips over the top caught Bath flat footed and Ryan Kline scored twice. A late 5 metre scrum saw Tyler Jerrum pick up and power over to complete a fine afternoon's work.
