Topic: Totally chaff-less coffee (8 msgs / 159 lines)
1) From: J. Paul Sheridan, III
Ok...you're all going to think I'm certified looney after this post, but
here goes anyway:
Is there anyone else out there that has pondered the quandary of internal
bean chaff, and how to remove it?  You know...it's the little bit of chaff
that is actually inside of the bean...the stuff you can see through the
little crack.
Well, I've always pondered what a completely chaff-less cup of coffee would
taste like.  I experimented with cracking open each bean, and removing the
chaff by hand.  Every time I attempted this, I got bored after 4-5 beans,
and just went ahead and brewed myself a "regular" cup.
But today, I had a revelation.  As I was grinding my beans in my
whirlyblade, I noticed all of the chaff was sticking to the side of the
grinder.  I had just cleaned it out, and I guess I created a little bit of
static electricity on the lid.  I opened the grinder to blow the chaff away
from the lid.  As I did, all of the loose chaff in the receptacle, also blew
away!  Note that the beans were hardly ground at all...they were more broken
than ground at this time.
So I gently shook the grinder, while blowing on the "broken beans" and in a
couple of seconds, had removed all the "inner-chaff" from that batch.
(Forget the fact that I blew the chaff all over the floor  :)
Anyway, the result: I'm sitting here sipping the smoothest cup of Panama
Lerida I've ever had.  Now I can't be sure if that's the result of the lack
of chaff, or I just caught these beans at the perfect "post-roast moment".
Has anyone out there ever warped their mind this far, and tried something

Another, more severe approach would be to go
through the decaf process, but just leave out
the part where the caffeine is removed. Then
you'd have chafless coffee.
If enough of the decaf steps were taken out,
so that all that was left was enough to
"dechaff", then you'd have beans that were
less modified than their decaf siblings yet
had no chaff but still had caff.
Of course this is industrial chemistry stuff,
so I don't think anyone of us is seriously
ready to try this. But it is significant to
note that decaf beans have no chaff.

You got my vote.
Never occured to me until now.
It is a good healthy sign that you got bored after 4-5 beans but I started
wondering why it took more than once to learn this.
Now I'm joining you.  I think I will use a whirlyblade to crack a few beans,
clean them up and put them in the Solis grinder to see what happens.

Wow, neat experiment.  Thanks for trying this and posting the 
results.  Yeah, it may have nothing to do with the chaff, but then again, 
it might.  Perhaps someone will try to reproduce it and we'll see.  For me, 
every day's brew is different, so I wouldn't be a really good candidate to 
try it, and I use a Turkish hand grinder.  But chaffless, smooth coffee may 
be a wave of the future.

Matter of fact, yes, and I've wondered about using one of those tiny
sandblasting things, kind of like an airbush.
Has anyone tried to collect a bunch of chaff and see if anything
can be brewed from it?
BTW I got the rock out and the grinder still works.

brewed from it?
An interesting article on Ethiopia by Michelle Williams, in Aprils Fresh Cup
Mag, writes that 'Hoja' is a tea made from coffee husks, served wtih milk
and salt.

I did something similar for a few weeks. The air was very dry and chaff 
would stick to the plastic cap of the whirly. I would bump the switch a few
times then shake out the chaff and resume grinding. I did not notice a
significant difference in flavors. I presume those with more educated
palates may taste a difference.
I will try collecting chaff and make a tea from it.

I just roasted some Sumatra M. and dumped the chaff from the trap into my 
french press. I brewed all of the chaff from the 2 ounce roast in 7 ounces
of near boiling water for 5 minutes. The result was a very weak (not enough
chaff, too much water) almost colorless tea. The taste was good, like a
cheap green tea with hints of green coffee. Yes, I tried the green coffee
brew mentioned in alt.coffee a few weeks ago and it had some terribly
unpleasant flavors.
The chaff from most coffees comes off very early in the roast and sits in
the bottom of the Aromaroast trap. The trap has a screen in the top and
bottom so the chaff is kept hot but below roasting temperature. The chaff
had a light brown color showing that some roasting had occurred.
This experiment has indicated that the chaff remaining on the roasted coffee
may contribute an extremely weak green or grassy taste. A lot of chaff
remains on some light roasted coffees. There may be a taste advantage to
post-roast chaff removal for those coffees.
