How to Make Nocino (Walnut Liqueur)

Each June 24th is the Feast Day of San Giovanni (St. John the Baptist), the patron saint of Florence, and traditionally it’s also the day when unripe green walnuts (noci) are gathered for making nocino, a complex, nutty, and slightly bitter dark-brown liqueur.

It’s usually served as an after-dinner digestivo, but it can also be used to “correct” a shot of espresso (espresso with a shot of liquor is called a "caffè corretto," or "corrected coffee"), poured over gelato, mixed into...MORE cocktails, or used in place of vanilla extract in baking (biscotti would be a great use for nocino).

Most commercial versions available these days contain artificial caramel color and flavoring and are not true infusions from fresh walnuts, so it's really worth it to make your own. Though it can be tricky to track down the green (sometimes known as "wet") walnuts, once you've got them, the rest is very simple and mostly hands-off—just requiring some patience, as it takes time for the final results.

Green walnuts are only available for a brief span of time every June, so while you don't necessarily need to make them on San Giovanni's feast day, the window of opportunity is limited (besides walnut liqueur, they are also used to make pickled walnuts). If you happen to live in a place where walnuts are grown, you can try buying them directly at a walnut farm. Or you can often order them online for delivery, such as from Haag Farms in California.

Even if you've had a walnut tree and helped with walnuts harvests, you may never have examined a green walnut up close. When sliced in half, the unripe walnut is clear, with a jelly-like texture. It can look like a tiny, translucent brain.

Recipes for nocino vary widely on the spices used. Some add juniper berries, vanilla beans, or orange zest. These instructions are very sparing with them, since a good nocino doesn’t taste strongly of any individual spice. The green walnut flavor should predominate: nutty, slightly bitter, a touch oaky, and a bit vanilla-y and sweet as well. 

Once you've gotten your hands on some green walnuts, let's start.

    Gather Your Ingredients

    You will need:

    • 1 gallon-sized glass jar with a lid
    • 25 green walnuts
    • 1 quart (4 cups) 190-proof Everclear
    • 4 whole cloves
    • 1 cinnamon stick
    • Zest of 1 lemon (you can use a vegetable peeler and make wide swaths of zest, to make it easier to strain the pieces out later. Try to avoid including the bitter white pith.)
    • 1/2 whole nutmeg (grated on all sides)
    • 10 coffee beans
    • Simple syrup: 3 cups sugar dissolved in 4 cups water (Added after the first 30-day infusion period.) 
    • Rubber gloves to wear when slicing the...MORE green walnuts

    Wash and Quarter the Walnuts

    After rinsing and drying the walnuts thoroughly, use a sharp chef's knife to halve the walnuts in half lengthwise, then halve each half again to form quarters.

    Note that they might be a bit difficult to cut, even though the immature shells lining the inside of the green husks should still be quite thin.

    It's a good idea to wear disposable rubber gloves for this part, or the walnut juice will stain your fingers and nails a yellow color that later turns dark brown.

    Place All Ingredients In the Jar, Shake, Then Set It and Forget It.

    1. Place all of your ingredients (except for the simple syrup) in the glass jar and then pour in the Everclear.
    2. Close the lid tightly and give the jar a good shake to distribute the ingredients.
    3. Then let it sit in a cool, dark place for 30 to 40 days.
    4. You can give it a little shake every now and then to redistribute the ingredients.

    Most recipes for nocino instruct you to leave it in a bright, sunny spot to macerate, but that seems counter to all logic about infusing liquor. Light can degrade and...MORE destroy flavor and aroma compounds, It is better to store the jar in a cool, dark cupboard. Just a few hours later, a peek into the jar revealed that the walnuts had already begun to oxidize and turn black (particularly any that were sticking out above the water line).

    Add the Simple Syrup, Then Hurry Up and Wait.

    1. Add simple syrup and shake well.
    2. Return jar to a cool, dark place and let sit for another 30 to 60 days.
    3. Finally, strain out the solids and your nocino is done.

    Most people advise letting it sit for about 40 days before adding simple syrup, then letting it sit for at least another 30 days before straining out the solids. At that point it is, in theory, ready to drink, but common wisdom (and the Order of Modinese Nocino) dictate that to really get something special, you need to then let it age and...MORE mellow for at least a year (better yet, two).
