Hi. I requested instructions/recipes on canning pinto beans, I got some
responses, and yesterday I canned them.

Here is my problem. I let them soak in water for 15 hours on the first
batch and 18 hours on the second. I left 1 inch of head space, and thought
I turned the heat down as instructed in the instructions that came with the
pressure canner. When I took out the completed jars, a lot of the juice had
boiled out and was continuing to do so after taking them out of the water.
For this reason two didn't seal.

What caused them to boil over? Did I not tighten the lids tight enough, did
I over fill the jars or what?
I am in the process now, of re-canning the jars that wouldn't seal and a few
pint jars that I filled up with soaked beans that were left over from
yesterday. Any ideas?

Thanks in advance, Dwayne
