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! -- garyZ Whirley-drip(paper)-black homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast
<Snip> 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. -- homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast

Do you regularly check for rocks before roasting or grinding?<<<<< 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.

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.

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! Linda
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. Ed Needham ed
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.
Ken wrote: <Snip> 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. -- Rick homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast
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 ).
