Ingredients and Tools to Make Black Walnut Bitters

Before you learn how to make black walnut bitters, gather everything you need.
 
The key ingredients are simple, but quality matters.
 

1. Black Walnuts

You’ll need about one cup of black walnuts.
 
You can use wild-harvested black walnuts if you have access to them, or buy them online or at specialty stores.
 
If you can’t find black walnuts, regular walnuts work, but the flavor will be milder when you make black walnut bitters.
 

2. High-Proof Alcohol

Use a neutral spirit like vodka, bourbon, or rye.
 
The alcohol should be at least 100 proof (50% ABV) to extract the flavors properly.
 
Higher-proof alcohol helps you make black walnut bitters that are potent and shelf-stable.
 

3. Flavoring Agents

Optional but recommended additions include cinnamon sticks, whole cloves, star anise, and dried orange peel.
 
These add warmth and complexity when you make black walnut bitters.
 

4. Tools

You’ll need a clean glass jar with a lid, a fine-mesh strainer, cheesecloth, and a dark glass bottle with a dropper for storage.
 
A kitchen scale helps if you want to be precise, but it’s not mandatory.
 

How to Make Black Walnut Bitters Step by Step

Now let’s get into the actual process of how to make black walnut bitters.
 
Follow these steps for a smooth, flavorful result.
 

1. Crack and Toast the Walnuts

Start by cracking the black walnuts and removing the shells.
 
Then spread the nutmeats on a baking sheet and toast them at 350°F for about 8-10 minutes.
 
Toasting enhances the flavor and makes your black walnut bitters taste richer.
 
Let them cool completely before moving on.
 

2. Combine Walnuts and Alcohol

Place the toasted walnuts in your glass jar and pour the high-proof alcohol over them.
 
Make sure the liquid covers the walnuts by at least an inch.
 
Seal the jar and shake it gently.
 
This is the first step when you make black walnut bitters, and it’s called maceration.
 

3. Add Spices and Let It Infuse

Add your cinnamon, cloves, star anise, and orange peel if using.
 
Shake the jar again and store it in a cool, dark place.
 
Let the mixture infuse for two to four weeks.
 
Shake the jar every day or two to help the flavors blend.
 
The longer you let it sit, the deeper the flavor when you make black walnut bitters.
 

4. Strain and Bottle

After infusing, strain the liquid through a fine-mesh strainer lined with cheesecloth.
 
Press the solids to extract as much liquid as possible.
 
Then funnel the finished black walnut bitters into dark glass bottles with droppers.
 
Label them with the date so you know when you make black walnut bitters next time.
 

Tips for the Best Black Walnut Bitters

Here are a few extra pointers to help you make black walnut bitters that taste professional.
 

1. Taste as You Go

Start tasting your infusion after two weeks.
 
If it’s not strong enough, let it sit longer.
 
When you make black walnut bitters, patience is your friend.
 

2. Balance the Bitterness

Black walnuts are naturally bitter, so a little goes a long way.
 
If your batch is too intense, dilute it with a small amount of fresh alcohol or a touch of simple syrup.
 

3. Store Properly

Keep your finished black walnut bitters in a cool, dark place.
 
They’ll last for years if stored correctly, so you can enjoy the batch every time you make black walnut bitters.
