Just like when drying herbs, if you have to pull the plants and let them finish maturing/drying that way, be sure to hang them upside down. That way gravity will help move any nutrients/water in the plants down to where the beans are, giving them the most time to mature before the plant is totally dried out.
found some info, too, which may come in handy if frost or lotsa rain show their ugly faces early:
"If fall weather is very wet or if frost threatens the harvest, pull plants early and finish drying under cover, such as in a shed, barn or basement. Beans will continue to mature in the pods even after they are picked, so don’t worry too much if you have to harvest immature beans.
As tender annuals, beans are very sensitive to frost. Plant once you’re sure all danger of frost has passed, and harvest early if needed, as described above, to avoid frost damage in the fall."
What's amazing is that they'll continue to mature in the pods! Ha!
When the pods are nice and yellowed and dry. There should be no softness or green on the pod. You will feel the beans inside them as bumps. You can see the bumps also. Just pick and crunch them apart and store the beans in a jar or ziplock.
