How To Make Walnut Stain Out Of Walnuts

You can make walnut stain out of walnuts by boiling the husks, shells, or even the whole nuts to extract their natural tannins, which create a rich, brown dye.
 
This is one of the oldest natural wood stains around, and it’s surprisingly easy to make at home with just a few simple supplies.
 
If you’ve ever wondered how to make walnut stain out of walnuts, you’re in the right place.
 
In this post, we’ll walk through exactly how to make walnut stain out of walnuts, what parts of the walnut work best, and how to apply it for beautiful results.
 
Let’s dive in.
 

Why You Can Make Walnut Stain Out of Walnuts

You can make walnut stain out of walnuts because the entire nut is packed with tannins, the same natural compounds that give tea and red wine their color.
 
Here’s why walnuts work so well for this:
 

1. Walnut Husks Are Loaded With Juglone

The green outer husks of black walnuts contain a compound called juglone, which is a powerful natural dye.
 
Juglone is what stains your hands when you handle black walnuts, and it’s the same compound that makes walnut stain out of walnuts so effective.
 
This is why the husks are the most concentrated part of the nut for making stain.
 

2. Tannins in the Shells and Kernels Add Depth

The hard shells and the nut meat also contain tannins that deepen the color of your stain.
 
When you make walnut stain out of walnuts using the whole nut, you get a richer, warmer brown than you would from husks alone.
 
These tannins bond with wood fibers, which helps the stain last.
 

3. It’s a Natural, Non-Toxic Option

Unlike many commercial stains that contain harsh chemicals, walnut stain made from walnuts is all-natural.
 
That makes it a great choice for furniture, toys, and projects where you want a safe, eco-friendly finish.
 
So when you make walnut stain out of walnuts, you’re getting a beautiful color without the chemical smell.
 

How to Make Walnut Stain Out of Walnuts

Learning how to make walnut stain out of walnuts takes just a few steps and a little patience.
 
Here’s the process:
 

1. Gather Your Walnuts

Start with black walnuts if you can find them, since they have the highest tannin content.
 
You can use the husks, the shells, or the whole nuts, though husks give the strongest color.
 
If you’re using whole walnuts, roughly chop or crush them to expose more surface area.
 

2. Soak the Walnuts in Water

Place your walnuts in a pot and cover them with water, using about two parts water to one part nuts.
 
Let them soak overnight to start releasing the tannins before you even turn on the stove.
 
This soaking step is key when you make walnut stain out of walnuts because it draws out more color.
 

3. Boil and Simmer

Bring the pot to a boil, then reduce the heat and let it simmer for one to two hours.
 
The longer you simmer, the darker your stain will become.
 
Stir occasionally and add more water if it evaporates too much, since you want to keep the liquid concentrated.
 

4. Strain the Liquid

Once you’re happy with the color, strain out the nuts and husks using a fine mesh strainer or cheesecloth.
 
What’s left is your homemade walnut stain, ready to use.
 
You can compost the leftover solids, so nothing goes to waste when you make walnut stain out of walnuts.
 

Tips for Using Walnut Stain Out of Walnuts

Once you’ve learned how to make walnut stain out of walnuts, a few tips will help you get the best results.
 

1. Test on Scrap Wood First

Always test your walnut stain on a scrap piece of the same wood before applying it to your project.
 
Different woods absorb stain differently, so this helps you avoid surprises.
 

2. Apply With a Brush or Cloth

Brush or wipe the stain on in thin, even coats, letting each layer dry before deciding if you want more color.
 
You can build up the shade gradually, which is one of the best things about walnut stain made from walnuts.
 

3. Seal the Wood After Staining

Because walnut stain out of walnuts is water-based, it needs a topcoat to protect it.
 
Apply a polyurethane or oil-based finish once the stain is completely dry.
 
This locks in the color and gives your project a durable, professional look.
