How To Store Black Walnuts In The Shell

You can store black walnuts in the shell for many months if you dry them properly and keep them in a cool, dry, dark place.
 
If you’ve been wondering how to store black walnuts in the shell without them going rancid or molding, the answer comes down to two things: proper curing and the right storage conditions.
 
Black walnuts are different from regular English walnuts because their shells are incredibly hard and their flavor is much stronger and earthier.
 
That tough shell actually helps protect the nut inside, which is why storing black walnuts in the shell is often easier than storing shelled ones.
 
In this post, we’ll walk through how to store black walnuts in the shell step by step, from curing to long-term storage.
 
Let’s get into it.
 

How to Store Black Walnuts in the Shell: The Basics

 
Storing black walnuts in the shell starts long before you put them in a bag or bucket.
 
The key is to dry them first, because fresh black walnuts have a lot of moisture that will cause mold if you seal them too soon.
 

1. Cure Your Black Walnuts First

 
Before you even think about storing black walnuts in the shell, you need to cure them.
 
Curing means spreading the nuts out in a single layer in a cool, dry, well-ventilated area.
 
Leave them there for about two to four weeks, turning them occasionally so they dry evenly.
 
You’ll know they’re ready for storage when the husks are completely dried and you can hear the nut rattling inside the shell.
 

2. Remove the Husks Completely

 
If you’re storing black walnuts in the shell, the husks need to go.
 
Husks hold moisture and will rot, which can ruin the nuts inside.
 
You can remove them by hand (wear gloves, because black walnut husks stain your skin for weeks) or by tumbling them.
 
Once the husks are off, give the nuts another week or two to dry before storing.
 

3. Choose the Right Container

 
When it comes to storing black walnuts in the shell, airflow matters.
 
You don’t want to seal them in an airtight container right away.
 
Instead, use a mesh bag, a cardboard box, or a burlap sack that lets air circulate.
 
Once they’re fully dry, you can move them to an airtight container for longer storage.
 

Best Conditions for Storing Black Walnuts in the Shell

 
Now that your black walnuts are cured and husked, here’s how to keep them fresh.
 

1. Keep Them Cool

 
The ideal temperature for storing black walnuts in the shell is between 32°F and 45°F.
 
A root cellar, a cool basement, or even the refrigerator works well.
 
If you’re storing black walnuts in the shell for more than a few months, the fridge is your best bet.
 

2. Keep Them Dry

 
Moisture is the enemy of storing black walnuts in the shell.
 
High humidity can cause mold, and mold will destroy your entire stash.
 
So keep them in a dry spot, and if you live in a humid climate, consider adding a desiccant packet to your storage container.
 

3. Keep Them Dark

 
Light exposure can cause the oils in black walnuts to go rancid faster.
 
So when storing black walnuts in the shell, choose a dark pantry, cupboard, or opaque container.
 

4. Protect Them from Pests

 
Mice, squirrels, and pantry moths all love black walnuts.
 
If you’re storing black walnuts in the shell in a garage or shed, use a metal container or a heavy-duty bin with a tight lid.
 

How Long Can You Store Black Walnuts in the Shell?

 
When stored properly, black walnuts in the shell can last for up to a year or even longer.
 
In the fridge, storing black walnuts in the shell can keep them fresh for 12 to 18 months.
 
At room temperature in a cool, dark place, they’ll stay good for about 6 to 12 months.
 
If you freeze them, black walnuts in the shell can last for two years or more.
 
Just make sure they’re completely dry before freezing, and thaw them gradually to avoid condensation.
 

So, How to Store Black Walnuts in the Shell?

 
Storing black walnuts in the shell comes down to curing them properly, keeping them cool, dry, and dark, and protecting them from pests.
 
If you follow these steps, you’ll be able to enjoy your black walnuts for many months, whether you’re baking with them, snacking on them, or giving them as gifts.
 
The hard shell of black walnuts makes storing black walnuts in the shell easier than you might think.
 
So go ahead and stock up.
 
With the right approach, storing black walnuts in the shell is simple, rewarding, and well worth the effort.
