What is the primary cause of bacterial contamination in grain jars?

I've had great success with grain jars but recently had two batches go boobs up with bacterial contaminations. What should I be looking out for?

Yourself.

Most bacterial contaminations come from us. Our breath, hands/fingernails, hair, skin are all huge bacterial playgrounds. Have you slacked off on your technique? Switched to a non-surgical mask? Stopped wearing gloves? Check up on stuff like that.

Sterile procedure, hydration level of grains before being loaded into jars for sterilization, and colonization temperatures.  What type of grain are you using?

Wild bird seed...

Sterile technique and pressure cook treatment has been the same... but perhaps the problem lies in the hydration level. I presume that "too dry" is better than "too wet" when it comes to grain jars?

This is correct.  In fact, that is a good motto to follow for colonizing mycelium, no matter what the substrate is.
