Once again for Brive it was the boot of Gaëtan Germain that did the damage to their opposition as the full-back kicked 18 points in victory
His 12 points in the first-half nudged Brive into a 12-7 lead at the turnaround, with wing Xavier Mignot hitting back with a try for Grenoble.
Hooker Arnaud Heguy then brought Grenoble back level with an unconverted try two minutes into the second-half but once again Germain got Brive ticking over, with his fifth penalty of the game on 49 minutes pushing the hosts back into a three-point buffer with plenty of time left.
Grenoble, desperate for a victory, would not go away and when scrum-half Charl McLeod crossed on 54 minutes, they went 19-15 ahead.
Replacement fly-half Jonathan Wisniewski added to his conversion with a penalty goal on 59 minutes but then Brive responded through Fabien Sanconnie's try. However, a missed conversion meant Grenoble remained in front at 22-20. Brive had 17 minutes to try and get the win.
And it was Germain who would have the final say as his penalty five minutes from time proved the match-winning kick as Brive prevailed.

La Rochelle 22-8 Castres
Stade Marcel Deflandre, La Rochelle
La Rochelle continued their impressive season as they beat Castres to go four points clear at the top of the Top 14 standings on Saturday.
Despite being 3-8 adrift with 34 minutes played due to hooker Jody Jenneker going over for Castres, La Rochelle kicked on from then on.
Zack Holmes kicked his second penalty before the break and his third two minutes into the second 40 to put the home side into the lead.
Then came a try from Victor Vito on the hour, which Holmes converted before adding another penalty that made it 19-8 with 14 minutes left.
Castres replacement Yohann Montes was sent-off late on, with Mohamed Boughanmi seeing yellow for La Rochelle, but it was Holmes who had the final say on the match as he sent over his fifth penalty of the night at Stade Marcel Deflandre to put the seal on another fine result.
