Subject: Question about grinding Yirgacheffe
 

Hello all,
newbie here with a Gaggia Classic and MDF grinder. I've had the set up for a little over two months. Learning alot from this wonderful site.
Recently took delivery of 1lb of Yirgacheffe from a roaster online; roasted on 7/26/2012.
My question, no matter the setting on the grinder, drip or espresso, I get chaff mixed in with the grounds. Is this normal? I assume that's what the light tan flakes are within the grounds.
I'm not very knowledgeable about roasting, however none of my other beans do this.
When I look at the Yirg beans before grinding, they look good, not oily, but a good portion of them have a light tan color in the crack.
I haven't contacted the roaster yet. I will email them though.
Anyone that can enlighten me would be most helpful.
thanks.... Pete

Pete:

From my experience, the bits of chaff are normal for light roasted coffees.  I see it on mine all the time.  It sounds like you've got a light roasted Yirgacheffe, which is what I think is the typical roast for these types of beans.  :-)

Thank you for the explanation and quick reply.
I guess my concern is/was how those flakes would affect the pull when I switch beans and grind for espresso since some of those flakes remain in the grinder.
I grind a small amount of beans before grinding for espresso to "clean out" the left over grinds, but the flakes still show up in the espresso grind. I haven't pulled a shot with those grinds yet.
Still learning.... :-)

The chaff isn't going to mess you up when it comes to espresso. The chaff is just about unavoidable in a lighter roast, and I've never encountered any issues what so ever when pulling shots with it.

Happy sipping!

Awesome, thanks Dave.
I was hoping that would be the case.
The chaff certainly doesn't affect the taste! Very tasty this morning! :-)

Hi Pete,

Yirgacheffe has a lot of chaff.  I don't think it makes a perceptible difference in taste so I wouldn't worry about it.  On the other hand roasting the stuff can be exciting.  I can almost always count on a chaff fire with it.

Hi Phil,
boy it sure does have alot of chaff. Leaves it behind in the grinder too!
So far, I haven't had any problems brewing though. Good tasting brew too!
Haven't tried grinding for espresso yet, but will very soon
Thanks for the reply...

Pete
