<p>As I mentioned in the post about the <a href="http://blog.khymos.org/2009/05/13/nocino-walnut-liqueur-part-i/">exciting color chemistry of nocino</a> I picked some unripe walnuts last year in August when visiting family in Germany. These walnuts were in fact a little to ripe to make nocino from. Preferably the walnuts should be picked end of June when you can still push a knitting pin through the center. Mine were stone hard, but <strong>I decided to give it a try anyway, and it shure was worth the bottle of vodka!</strong> I checked a <a href="http://simplyrecipes.com/recipes/nocino/">couple</a> of <a href="http://ilforno.typepad.com/il_forno/2004/07/drink_your_waln.html">recipes</a> and found that many use cinnamon and cloves together with lemon (with peel). I figured I also wanted to try star anise and proceeded with two batches.<br />
<span id="more-1660"></span><br />
<strong>Nocino extracted with 45% ethanol</strong><br />
<em>For extraction (> 3 months)</em><br />
529 g unripe walnuts<br />
385 g 60% ethanol<br />
140 g water</p>
<p><em>Spices and sugar</em><br />
4.0 g cinnamon stick<br />
1.2 g star anis<br />
1.2 g cloves<br />
12 g lemon wedge<br />
100 g sugar</p>
<p><strong>Nocino extracted with 60% ethanol</strong><br />
<em>For extraction (> 3 months)</em><br />
481 g unripe walnuts<br />
436 g 60% ethanol</p>
<p><em>Spices and sugar</em><br />
0.8 g star anis<br />
7.8 g cinnamon<br />
12 g lemon wedge<br />
100 g sugar</p>
<p>I covered the walnuts with alcohol in August last year and let them rest for almost 8 months (you can probably do with less, especially if you quarter the walnuts). I then removed the walnuts and added spices, lemon and sugar. After two days I removed the lemon wedge and approximately one month later I filtered off all the spices. As you can see from the pictures below the filter easily clogged. Using normal coffee filters I had to change them roughtly 4-5 times for each batch. I let the filtered nocino rest for some more weeks and then carefully decanted it into a glass bottle, leaving the newly set residue behind. If desired the nocinos can be diluted with water and/or vodka.</p>

<em>Precipitation in nocino extracted with 60% ethanol shown (upper left), filtering was slow (upper right) due to extensive clogging (lower left). A black film had also formed on the inside of the glass.</em></p>
<p><strong>Nocino tastes marvellous, despite the motor oil like appearance during steeping! </strong>The difference between the two ethanol concentrations was less than I had expected. There was significantly more precipitation of black particles with the higher ethanol concentration. Both were however very drinkable! The only thing I might change the next time I attempt this is the amount of spices. I felt that the spices were perhaps a little too dominant and overpowered the walnut flavor, but the flavor was nice anyhow. Since I used walnuts that were a little too ripe it might be that less flavor was extracted, so I assume that my nocino is weaker compared to nocino made with the proper unripe walnuts. This might as well explain why the spices were a little too pronounced.</p>

<em>Update: Reading Elise&#8217;s comment below I realized that there was one thing I forgot to mention. Since the walnuts were picked late I could neither cut them in half nor pierce them. After extraction I tried to cut a little into the soft shell under which the black walnut shell is barely visible.</em></p>
<p>I&#8217;ve seen a recommendation to try nocino with strong cheese whereas others prefer it over vanilla ice cream. I&#8217;ve also come across <a href="http://www.roastingrambler.com/2009/01/christmas-and-new-years/">two</a> <a href="http://www.oregonlive.com/mix/index.ssf/2009/05/nocino_liqueur_ice_cream.html">recipes</a> for <strong>nocino ice cream</strong> so it&#8217;s a quite versatile liqueur!</p>
