How To Make Walnut Liqueur

You can make walnut liqueur at home by soaking green walnuts in alcohol and sugar until the flavors meld into a rich, dark, nutty spirit.
 
It’s a traditional drink in many European countries, often called nocino in Italy and orahovac in Croatia.
 
The good news is that making walnut liqueur is surprisingly simple, though it does require patience.
 
If you’ve been wondering how to make walnut liqueur without any fancy equipment, you’re in the right place.
 
In this post, we’ll walk through how to make walnut liqueur step by step, from harvesting the walnuts to bottling the finished drink.
 
Let’s dive in.
 

How to Make Walnut Liqueur: The Basics

Learning how to make walnut liqueur starts with understanding the three core ingredients and the timing involved.
 
Here’s what you need to know before you begin the process of making walnut liqueur.
 

1. You Need Green Walnuts, Not Ripe Ones

The most important part of how to make walnut liqueur is using green, unripe walnuts.
 
These are walnuts harvested in early summer, usually around late June or early July, while the shell inside is still soft and the outer husk is bright green.
 
If you use mature brown walnuts, your walnut liqueur won’t develop that signature deep, bitter-sweet flavor.
 
You’ll know green walnuts are ready when you can easily pierce them with a knife.
 

2. The Three Simple Ingredients

To make walnut liqueur, you only need a few things: green walnuts, a neutral high-proof alcohol like vodka or grain alcohol, and sugar.
 
Many people also add spices such as cinnamon sticks, cloves, and lemon zest to enhance the walnut liqueur.
 
These extras aren’t mandatory, but they give your homemade walnut liqueur a warmer, more complex character.
 

3. Patience Is Everything

When you make walnut liqueur, the actual hands-on time is short.
 
What takes long is the infusion and aging process.
 
Your walnut liqueur needs at least six weeks to steep and often several months to mellow into something really smooth.
 
That’s the trade-off for how easy it is to make walnut liqueur at home.
 

Step-by-Step Guide to Making Walnut Liqueur

Now let’s get into the actual process of how to make walnut liqueur from scratch.
 

1. Prepare the Green Walnuts

Start by washing your green walnuts and cutting them into quarters or halves.
 
Wear gloves because green walnut husks stain your hands badly and leave a brown mark that lasts for days.
 
As you cut them, discard any that are brown or rotten inside.
 

2. Combine Everything in a Jar

Place the chopped green walnuts into a large glass jar with a tight-fitting lid.
 
Pour your alcohol over them until they’re fully submerged, then add your sugar and any spices you’re using.
 
Give the jar a good shake to help the sugar start dissolving.
 

3. Let It Steep in the Sun

This is the traditional method for how to make walnut liqueur the old-fashioned way.
 
Set your jar in a sunny spot, like a windowsill or porch, for about forty days.
 
Shake the jar every day or two to keep everything mixed.
 
The liquid will slowly turn from clear to a dark amber, then nearly black.
 

4. Strain and Bottle Your Walnut Liqueur

After six weeks or so, strain the liquid through a fine mesh sieve lined with cheesecloth.
 
Squeeze the solids to get every last drop of your walnut liqueur out.
 
Pour the strained walnut liqueur into clean bottles and seal them tightly.
 

5. Age It for the Best Flavor

Your walnut liqueur is technically ready to drink now, but it will taste harsh.
 
Let it age in a cool, dark place for at least three months, ideally a full year.
 
The wait transforms your walnut liqueur into a smooth, syrupy drink with deep caramel and spice notes.
 

Tips for the Best Homemade Walnut Liqueur

A few small tweaks make a big difference when you make walnut liqueur.
 

1. Adjust Sweetness to Taste

Some people like their walnut liqueur sweeter, others prefer it more bitter.
 
You can always add a little simple syrup after straining if it’s too strong.
 

2. Use Quality Alcohol

Since your walnut liqueur is mostly alcohol and walnuts, don’t use the cheapest stuff you can find.
 
A decent vodka or everclear works well for extracting flavor cleanly.
 

3. Store It Properly

Keep your walnut liqueur in a dark, cool cabinet away from heat and light.
 
Stored well, a homemade walnut liqueur can last for years and only gets better with time.
 

So, How Do You Make Walnut Liqueur?

You make walnut liqueur by soaking chopped green walnuts in alcohol with sugar and spices, then straining and aging the mixture for several months.
 
It’s a slow process, but the payoff is a rich, homemade walnut liqueur that beats anything store-bought.
 
Once you learn how to make walnut liqueur, you’ll want to make a batch every summer.
 
Grab those green walnuts while they’re in season and get started.
