Accurately saved dry beans can stay edible for 25 to 30 years, however will they sprout? The power to develop a brand new crop of dry beans from saved beans would considerably enhance our self-reliance. We determined to conduct an experiment to see which of our previous beans would sprout.
Will previous saved dry beans sprout and produce a brand new crop of beans? The germination price of dry beans decreases considerably with age and is impacted by storage situations. Our analysis research demonstrated that it’s potential for 29-year-old beans to sprout, however the germination price of newer beans is considerably increased.
On this submit, we’ll share the outcomes of our bean sprouting experiment. We took a random sampling of 23 completely different dry beans. Variables embrace selection, age, storage situations, storage container, and sprouting technique. The outcomes proved to be fairly fascinating.
The thought behind this experiment originated from considerations expressed in feedback on our YouTube channel. We performed two analysis research utilizing dry beans from our personal meals storage to find out if previous beans would soften up and develop into edible. You might be all in favour of studying extra in regards to the outcomes of these research.
Ideally, you’ll want to choose the highest quality dry beans which might be accessible. The germination price will considerably enhance with contemporary beans.
That is our process for sprouting beans and legumes in jars:
- Type beans and take away damaged beans or rocks.
- Rinse beans nicely.
- Place beans in a jar and canopy with water just a few inches above the beans. The beans will double or triple in measurement so depart room for enlargement.
- Soak for 8 to 12 hours or in a single day.
- Drain the soaking water and rinse.
- Cowl beans with a sprouting lid, cheesecloth, or materials that may permit for good airflow.
- Invert the jar at an angle that may permit for the liquid to empty out and nonetheless permit for air motion.
- Rinse the beans 2 or 3 instances every day till the sprouts are the specified measurement.
Sprouted beans may be eaten uncooked in a salad, sautéed, or cooked in a soup. They solely final just a few days and needs to be saved within the fridge.
Good beans and legumes for sprouting embrace lentils, chickpeas, white beans, black beans, mung beans, soybeans and adzuki. Pinto beans will sprout, however the success price tends to be decrease.
Kidney, lima, and broad beans have to be cooked earlier than consuming. It’s in all probability finest to not sprout these for consuming.
We designed this experiment with the perfect number of dry bean samples accessible to us. Not all variables may very well be accounted for, however the outcomes are worthwhile.
Dry Bean Samples
For this experiment, we collected 23 random samples of dried beans. They vary in age from newly bought to 29-years-old. Samples included black beans, pinto beans, white beans, lentils, kidney beans, lima beans, pink beans, purple beans, and backyard inexperienced beans.
Storage situations ranged from the kitchen pantry to a basement storeroom to a bucket in a driveway. Optimum storage situations for dry beans are in an hermetic container in a cool, dry, darkish location. A few of our samples met that standards, others didn’t come shut.
Experimental Design
Every of the bean samples have been divided into 3 components. A small bag containing the unique beans was put aside and labeled for reference.
Jar Germination
One portion of every pattern was positioned in a pint mason jar and coated with a mesh cloth. The beans have been rinsed and coated with water. The beans have been soaked in a single day and drained.
The jars of beans have been positioned at an angle to permit for good drainage and airflow. They have been rinsed twice a day for 4 days.

Ziplock Bag Window Germination
Ten beans of every pattern have been positioned in a labeled Ziplock bag together with a moist paper towel. The baggage have been taped to the within of a south going through window and left alone for 4 days.

Outcomes Have been Noticed and Picture Documentation Created
The samples of the beans have been in contrast, and the outcomes documented. Data was positioned on a spreadsheet and the outcomes have been rigorously evaluated.

Profitable Beans Planted
Beans that had demonstrated the flexibility to germinate have been planted in moist potting soil in a heat room underneath develop lights.
In circumstances the place only some beans germinated, the entire beans have been planted. Ten beans from extremely profitable samples have been planted. A double row of 5 seeds every have been planted.

Full outcomes together with photographs may be discovered on this video.
Components Contributing to Profitable Germination
Clear developments emerged as we seemed on the information. The next have been our common observations:
- The age of the bean performs a task in sprouting success. Usually (and as we might count on), the older the bean the decrease the sprouting success.
- Some types of dry beans germinated higher than others. The black beans appeared to have the perfect success price regardless that one of many samples was fairly previous.
- Storage situations over time make a big distinction within the viability of the beans. Beans that had been left uncovered to vital fluctuations in temperature, saved in a heat surroundings, or uncovered to daylight had little to no profitable germination.
- Window sprouting offered higher outcomes than jar sprouting in virtually each case. This is able to point out that the additional mild or warmth was a think about germination.
See the abstract spreadsheet beneath for added particulars.

Failure to Thrive Publish Germination
One fascinating factor to notice is that a number of of the beans confirmed proof of sprouting however then did not thrive as soon as planted. Germination alone shouldn’t be a transparent indication of the flexibility to supply one other era of beans.
We spent a few weeks researching whether or not previous dry beans may be relied on to germinate. I’m not assured that the speed of germination of older beans was excessive sufficient to supply a survival crop. If you wish to have the flexibility to sprout or plant your dried beans, we advocate taking the next steps.
- Rotate your dried beans. Plan to make use of your saved beans usually in your regular weight-reduction plan and substitute them yearly. Good rotation will guarantee that you’ve a contemporary provide of dried beans that may sprout once you want them.
- Package deal the dry beans appropriately to increase the standard shelf life.
- Retailer dry beans in a cool, dry, darkish location.
Greatest Storage Situations for Dry Beans
Dry beans retailer finest in a cool, dry, darkish location in air-tight decreased oxygen packaging. You may be taught extra about learn how to bundle dry beans for the longest shelf life in these articles.
The right way to Use Previous Dry Beans
Will previous storage beans and legumes germinate? Some will, whereas others won’t. You may eat dry beans which might be 25 to 30 years previous if they’ve been saved appropriately. Soak them in a single day in water with a little bit little bit of baking soda and use a pressure cooker. You’ll have success each time.
Another choice for previous dry beans is to grind them into flour. You can also make immediate refried beans, use bean flour to thicken soups or sauces, or substitute as much as 1 / 4 of the flour in your favourite baked items.
Simply just be sure you use a grinder designed to grind beans and corn or you might harm your grain mill. I actually just like the NutriMill as a result of it can grind grains, dry beans, and dry corn.
Add dry beans to your weight-reduction plan and retailer them together with your fundamental meals storage. They’re a dietary powerhouse and could be a nice asset throughout difficult instances.
Thanks for being a part of the answer!
