Prepare your pressure canner for canning based on the manufacturer's instructions. For most canner models, that means putting in the bottom rack and adding a few inches of water. Pre-heat it on the stove to just simmering, around 180 degrees F.
Bring a kettle of water to a boil on the stove (to fill any jars if you don't have quite enough liquid in the bean pot).
Prepare 6 pint jars (or 3 quart jars) per batch. Divide the beans evenly across all the jars using a slotted spoon, leaving 1-inch headspace. Top the jars with the canning sauce from the bean pot, still maintaining 1-inch headspace.
If you're short on liquid, pour in a bit of water from the pre-heated kettle. The beans should be under the liquid line in the jars, but there should still be a 1-inch headspace at the top of each jar.
Wipe rims, apply canning lids and seal to finger tight with canning rings.
Load the jars into your pressure canner.
Put the lid on the canner and bring it up to temperature, but don't seal it yet. Allow the steam to vent for 10 minutes before sealing up the canner and bringing it up to pressure. (See notes for pressures based on altitude.)
Once at pressure, process the jars for 80 minutes for pints and 95 minutes for quarts.
After the canning time is complete, turn off the heat and allow the canner to cool completely before unloading the jars.
Once the jars are unloaded, check seals and store any unsealed jars in the refrigerator for immediate use (within 1 to 2 weeks). Properly canned and sealed jars will maintain their quality on the pantry shelf for 12-18 months.
Refrigerate after opening.
