Black Walnut Harvest

 It's black walnut time.  I haven't improved my process much over what I have discussed before.  It's still a multi-step, somewhat slow process. I have gotten faster: a full 5-gallon bucket can be processed in 30-40 minutes.

The first step is to gather them; shown above are some walnuts that had been on the ground no more than about four days.  They soon start to turn black, as noted previously; the hull rapidly breaks down.  That's what it's designed to do.  The hull contains a hefty dose of juglone to suppress nearby vegetation, thus giving the nut the best chance to sprout and grow.

When the hull is black and soft, it can still be removed, though it gets a little more difficult.  If it dries down around the nut, as sometimes happens, it's extremely hard to remove, as discussed before.

Hammering the hulls off is messy and slow.  I'm still nowhere as fast as Rbeckism.  He spent about 5 seconds per walnut; I average a more (maybe 10 seconds), although speed is improving.

Once the majority of the hulls are knocked off:

 

I swirl them in water a few times to get them something approaching clean.

 

 

 

 

I'm not going for works of art; these are clean enough.  I've noticed over the years that walnuts are vulnerable to mold when the unhulled nuts are stored in buckets and when they are wet (as in the picture above) after hulling.  They need to be dried relatively quickly, and will retain moisture for a time. Shown above are nuts immediately after washing; below are several boxes of nuts, with the middle three boxes nearly dry.

 

One caveat, as noted previously:  the hulls stain.  If there are no husk flies, the juice from the hulls is a dark yellow, but it causes dark brown stains.  The left glove above is the one that holds the hulls while I knock them off with the hammer; it's badly stained.  Somewhere along the way, I got a small leak in my left glove, which led to my hand getting some stain on it.

This isn't entirely surprising.  The ridges on the nuts are very sharp.  One probably nicked a little hole in one of the fingers, even though the gloves are very thick.

 I'm still in the midst of the harvest.  In mid-October, my tree is at peak nut drop (curiously, the other tree didn't produce any nuts this year--which is fine...the one that has a bumper crop is the best tree for nut quality).

 To some degree, hulling is the easy part.  Next comes cracking...
