But this afternoon was all about the Guinness Premiership, the club's bread and butter. And it was an afternoon to remember.
Bryan Redpath's men were two tries to the good at half time and looked well set for the win but scored four more after the break to chalk up their first Premiership try scoring bonus point of the season.
It wasn't easy. Quins are too classy and professional outfit for that. But a superb effort up front paved the way for victory, creating the chances which the backs finished in style.
Gloucester, backed by a lively crowd, started with purpose and the ball was quickly being fizzed along the backline but Quins were organised in defence.
The pack were also evidently fired up and had the Quins eight in trouble on their first put in, forcing a penalty wide out. The angle was no issue for Nicky Robinson and his penalty gave Gloucester a 3-0 lead after four minutes.
The Quins scrum was creaking but it was a penalty for pulling back Eliota Fuimaono-Sapolu as he chipped ahead which gave Gloucester their next chance and Robinson's penalty doubled the lead.
Gloucester were well on top and the first try came on 17 minutes. Clean lineout ball was fired into midfield and Gareth Delve burst through the middle. Fuimaono-Sapolu was in support and gave the scoring pass to Lesley Vainikolo. Robinson converted for 13-0.
Quins had had litle ball to work with but finally got on the scoreboard as they forced a turnover deep in the Gloucester half and Nick Evans stroked the penalty in off the left hand upright.
It sparked a good little spell for Quins with Evans pulling the strings, Gloucester seemingly having lost focus for a minute. Another penalty was the reward and Evans made it 13-6 after 26 minutes.
Gloucester had an immediate chance to respond as a clean catch of the restart by Alex Brown forced Quins to concede a penalty immediately afterwards but Robinson pushed his kick wide left.
Quins were coming into the game more and Gloucester were forced into some serious defence near their own line including defending a 5m line out. Akapusi Qera was forced off with a blood injury but the home side held.
And, with half time approaching, Gloucester pounced. Turnover ball on midfield put Quions on the back foot and Fuimaono-Sapolu's chip over the top created havic. Vainikolo's presence forced the error and Molenaar pounced. 18-6 as Robinson's conversion from out wide stayed left of the posts.
Gloucester finished the half on a high looking for a further score and looked well capable of the task but Quins dug deep in defence to keep the half time score at 18-6.
The momentum had switched between the two sides as the first half had progressed. Gloucester had started well but Quins had bounced back until Gloucester's late surge.
There had been plenty to keep the crowd warm at a freezing Kingsholm and lots to play for in the second half.
Gloucester had an early chance to strike in the second period with a lineout 10 metres from the Quins line. However, the catch and drive was well defended and Quins midfield defence was up to the task as the ball was shipped wide.
The midfield collision was costly for Gloucester as the excellent Fuimaono-Sapolu limped off to be replaced by one of last week's heroes Tom Voyce.
With the rearranged midfield still getting to know one another, Quins' replacement Sam Smith wriggled his way through but Evans long, potentially scoring pass, floated forward.
Gloucester's pack promptly forced a couple of penalties and the Quins front row received a lengthy lecture from referee David Rose.
The pressure finally told. Delve picked up and went blindside and Vainikolo smashed his way inside to keep the ball alive. Swift hands moved the ball across the backline and James Simpson-Daniel dived gleefully over for the third try. Robinson's touchline conversion was superbly struck and on the money. 25-6 after 50 minutes.
Everything was going Gloucester's way. Tom Guest pounced on a turnover and David Strettle's hack ahead seemed certain to result in a score but the ball bounced wickedly and Gloucester got back.
Gloucester were pushing for the bonus try and it came before the hour as Gloucester chased a kick through and Gareth Delve charged down the attempted clearance. The number eight stayed cool and offloaded to Nicky Robinson whose swift transfer to Tom Voyce sent the winger on his way under the posts untouched. Robinson converted and Gloucester were home and hosed at 32-6.
The game went through a scrappy phase as the inevitable host of replacements took place and a couple of timely interceptions saved Quins as did the right upright as Robinson's 68th penalty stayed out.
Quins, to their credit, looked for a consolation but two late tries from Simpson-Daniel, the first after a lung bursting interception and 50m run from Delve, were the final nails in the coffin and take Gloucester to sixth place in the table.
Tough challenges lie ahead, notably the trip to Welford Road next weekend to take on Leicester. However, everyone at Gloucester will enjoy the moment and report for work on Monday in good spirits.
