The official website rounds up the European Challenge Cup pool draw that was made by ERC on Wednesday.
Gloucester will be up against two French sides and a Romanian outfit in this season's European tournament.
The West Country side have been drawn alongside French sides Toulon, Bayonne and Romanian side Bucuresti.
There has been a change in format for the new season's competition, and it will now be run on a pools plus knock-out basis and will be composed of 20 teams. Teams have been drawn into pools of four (five pools of four) and will play home and away matches.
The winners of each pool and the three best runners up will qualify for the quarter-finals. The semi-finals will be one-off matches played at home venues and the Final at a neutral venue.
The new Pool format will replace the previous season's knock-out structure and the European Shield tournament.
Pool 1 - Viadana, Narbonne, Northampton Saints, Bristol
Pool 2 - Agen, London Irish, Parma, Pau
Pool 3 - Gloucester, Bayonne, Bucuresti, Toulon
Pool 4 - Borders, Brive, Newcastle Falcons, l'Aquila
Pool 5 - Connacht, Montpellier, Worcester, Catania
The fixtures and when each home and away tie is being played will be confirmed at a later date.
Speaking straight after the game, skipper Billy Twelvetrees told GRTV that losing at home to Bath, in front of a tremendous home support, was desperately disappointing and that the whole team were hurting in the dressing room.
Speaking to the local media this week, Richard Hibbard expressed his excitement ahead of the West Country derby and that there is an extra spring in the step of the Cherry and Whites ahead of the tough challenge.
With such a short turnaround between the two games, and Gloucester looking to reintegrate several players into the line-up after the Autumn international series, Tom Savage told GRTV that the Cherry and Whites will keep changes to a minimum for the European Rugby Challenge Cup game in Zebre on Saturday.
On a tough evening at Kingsholm, Gloucester could escape neither a suffocating Bath defence, nor the whistle of referee Greg Garner as six penalties and a penalty try paved the way to a 39-16 win for the visitors.
