I canned a mess of beans last fall, too, for the first time, and it's fantastic, isn't it?
I found various directions, ranging from just dump the dried beans (soaked and not) in the jar, fill with water and process (haven't tried that) to cook the beans 30 minutes before filling jars and processing. . .
I went ahead and canned a test batch - I soaked all of the beans overnight then I took 1/3 of the beans, brought the to a boil, then shut them off and filled jars, 1/3 of the beans I cooked for 30 minutes, then filled the jars, and the remaining 1/3 I cooked 15 minutes.
I also used the cooking water for half of the beans and fresh boiling water for the other half.
We were happiest with the beans that had only been brought to a boil, then shut off, and we preferred the beans canned in fresh water, not cooking water. The others, well, they made mighty fine refried beans, which were lovely in burritos!
I am wondering now what would happen if I ONLY soaked the beans before canning them. . .

Next batch, I think I'll try a couple of test jars.
