Ensure that the bean is fully mature before you store it. They will eventually dry on the vine if you leave them there. You can wait until the end of the season to pick these beans and store them. The pods will turn brown.
Pull the pods from the plant.
Open the pod and remove the seeds.
Place the beans on a plate and let them set for a day.
Put beans into a covered container and store them in a cool, dry and dark area. You can store the beans for three to five years if they are properly sealed from moisture.
