Topic: Raimy rocks! (13 msgs / 344 lines)
1) From: Gary Zimmerman
I have a love-hate relationship with Yemen Mokha Raimy:
I love the jammy-raisiny/bourbon-chocolate flavors it imparts.
I hate that I need to carefully go through each cup of beans, before 
roasting, to remove rocks.  I almost always find one or two in there, and 
more as I get near the bottom of my bag.  The rocks not only make roasting 
and grinding difficult, but also can add a dirty flavor to the coffee.
Since I use a stovetop cranking corn popper to roast, it's usually evident 
while I roast if I've missed a rock or two.  If they get through there, 
it's painfully obvious when I hand grind the beans in my Turkish 
grinder.  I've gotten better at picking out the rocks from the green beans, 
so this is rare for me now.
But I was wondering what happens to you folks with expensive electric 
grinders if a rock gets left in your roasted beans.  Are the burrs hard 
enough to chew up the rocks without complaining, or does it damage the 
grinders?  Do you regularly check for rocks before roasting or grinding?
Also: Can anyone give me your opionion on how Tom's other Yemens (Ismaili 
and Mattari) compare to the Raimy?
Thanks!

I just finished a normal 8 minute roast of the Raimy, my 3 minute profiles
do not do it justice. I found a small white stone on dumpout. I usually just
do a preroast "pour check", looking for obvious defects as it goes into the
measuring cup, but missed the stone. I have never been aware of any stones
going through my Antigua grinder. These and the similar Solis grinders have
a clutch that will slip if something prevents the inner burr from turning.
Judging from the reports of quickly dulling burrs, I suspect the metal is
soft or brittle and will be damaged by stones in spite of the clutch. The
replacement cost for the outer burr is too large a percentage of the Antigua
grinder cost, so a damaged burr will "total" the grinder.
In my limited experience, Yemen beans have no more stones than any other
origin.

I'm not sure, but I can't imagine it would be pretty... I've got a cooling 
tray, 8" x 14" and 3/16" thick aluminum, with 1 1/4" raised edges. Several 
pounds of cold aluminum will really suck the life out of anything hot, in a 
hurry. I spread the greens out in it, to check for the occasional stinker, 
and also look through the finished product for odd bits. I've spotted a few 
chunks, rocks, concrete and bark. Mostly ethiopian, but one suprise rock 
from costa rica.

Hi,
First of all, I get the digest, so I wasn't sure how to post a reply--I =
cut and pasted this message and added the >>>'s by hand (pain in the =
neck).  Anyone have a better suggestion?
Anyway,  I have 2 Antiguas (got one on clearance at Target--couldn't =
pass it up!), and have gotten a rock in each of them.  The first time it =
happened, the rock got really wedged in , and I had to use a screwdriver =
to pry it out.  I also broke one of the tiny plastic tabs that holds the =
top burr in the plastic collar, so I just took the top burr from my =
second grinder and used that.  Then it happened again a couple of weeks =
ago.  Same deal to get it out, and again broke the little plastic tab.  =
I called Bodum in New York (number is on their website), and told them =
what happened, and they sent out a replacement burr at no charge!  It =
doesn't appear to be brand new (some gunk in the grooves), but it works =
great. I'm a happy camper!

Maybe I'm grinding rocks right and left, but I rarely find rocks in my
beans.  Maybe once a year or so I find something.  Once in a blue moon I get
a stink bean and a pot of coffee tastes nasty.  Now I'm probably going to
jinx myself by saying that and grind a nail or something.

Since one of my hobbies is grinding rocks, I can speak to this.  The 
first thing is to remember that grinder burrs wear down with nothing 
but coffee going through them.  Anything harder and the  grinder's 
burrs degrade  quicker.  Some soft rocks would do no more damage than 
ten to twenty pounds of coffee.   Some very hard ones would finish off 
even the best set of titanium burrs.

Once saw a roaster in Cedarburg WI pick out a stink bean-what do they look
like-how do u recognize one of these critters.

Au contraire!  I took my Solis Maestro apart because I was getting a lot of
variation in output particle size and found a damaged burr in the outer
(fixed) burr assembly.  Only one "tooth" on the burr was damaged, but it
took me _hours_ to file it down with a tungsten file.  They're not soft,
*or* brittle.  :-)
As it turned out, though, the burr wasn't the bad part.  Something (probably
coffee particles) had gotten between the outer burr and it's seat (it
normally floats a little bit) and after I cleaned it and put it back
together it worked fine.
A few weeks later it acted up again, and this time I simply pulled the
hopper off and reseated the outer burr.  It's worked fine since.  Someone
mentioned using a piece (or was it two?) of business card to stabilize the
outer burr assembly.

I've not had a lot of luck finding them.  Generally, they are darker and
sometimes shriveled up.  Pretty much what you would expect a rotten bean to
look like.
Buying beans from Sweetmarias has minimized it to almost none, but
occasionally I get one still.  I am not one to fuss over each bean.  I pretty
much weigh the beans before roasting, give them a few tosses in a four cup
measuring cup, and if I see something weird, I pick it out.
If a stinkbean gets into your pot of coffee, you'll know it--'no doubt'.
You'll think you are drinking Vietnam Robusta (all stinkbeans ).

I also grind with a whirly blade, but have never found rocks.  I go examine 
a bag (maybe you are just special)
<Snip>
I like Raimy the best.  While the other two are good, I find them not as rich.

There are variations, anything works as long as it's not too vague or 
confusing.

My email client (Outlook) doesn't put the quote characters in when html
email format is used by the sender.  In that case, I put  before
the quote and  after it ... sort of an xml type o thing I guess.
Simple and clear imo.
