Help identify beer...

[Apoxbrew]

So the wife and I had this sour beer at a local bar that was awesome, but I can't remember what it was. I'd call them, but they're closed today, so I thought I'd ask here.

Here's what I know:

-It was called "Cuve de J" the "J" being the part I forget.
-Assuming the bartender knew what he was talking about, its made south of France.
-The tap handle was covered in a small blue and white diamond pattern.

Anyone know what beer this was?
