That could be a “curb-cut effect” result for the initial purpose - used to ensure volume, but doubles as a good way to align a label.

I thought it was to have a place for the label. If dimple wouldn’t it be easier to push it up from the bottom where there’s a simple already?

The labels go on the flat sides, and the dimples would get in the way. The bottoms of the jugs are usually a thicker plastic, but I can’t say for sure that this is why they don’t put the dimple there.

Labels that are the same shape as the dimples.

I was going to speculate that the dimensions of the bottom could be important for structural reasons, so if that was the case, a volume-adjustment dimple wouldn’t be a good idea there.

The arch in the bottom serves a structural purpose, but the tolerances are definitely large enough to accommodate volume calibration.
