Playing as a combined academy/county team, the Gloucester team ran out 45-10 winners over their Cardiff counterparts at a sun bathed Hartpury College.
The side, coached by first team stalwart Peter Buxton, started in traditional Bucko fashion with captain Joe Mullis going over from a catch and drive off a lineout within the first 5 minutes.
Fly half Elliot Creed converted to grab his first points in a personal tally of 20 points on the day.
The Gloucester pack continued to dominate throughout the first half which allowed the Gloucester backs to show what they could do.
Ryan Kline ran a great line from centre to cross under the posts while winger Alesandro Tiraboschi showed his skill and pace to round the wide defence and Elliot Creed powered over from following a searing 30 metre break by outside centre Ollie Thorley.
Openside flanker Mullis rounded off a fine first half performance by running in a great try created by the quick handling and strong running of Kline and Creed.
Creed again added the extras bringing the half time score to 33 - 0.
In the second half Gloucester introduced a number of replacements, but it was Cardiff who started the strongest with their scrum half darting over from close range.
There were some notable performances however from some new faces to the Gloucester squad with Tobin Ronald making a strong impact at blindside flanker, centre Dan Scholey and locks Harry Wilson and Will Greenway all impressing.
Full back Joe Gare and Creed added two further tries in the second half for the home side, before Cardiff had the final word to bring up a final score of 45 - 10.
Junior Academy Manager Billy Clark commented
"These fixtures are not about results, they're about putting our players in testing environments and seeing how they respond.
"We want to play a fast, off loading style of play in keeping with club philosophy. But the test for these guys is not to force things, they have to learn and understand how to control games and exploit chances when they are created. The pleasing thing today is that they did that pretty well.
"Obviously there were errors and examples of taking the wrong option. But it's through these errors that we learn, and it was great to see the lads backing their skills and trying things under pressure against a good Cardiff side."
