Topic: Yemen Too Dark (15 msgs / 403 lines)
1) From: Jamie Dolan
HI;
I guess this question is going to have an obvious answer, roast for
less time, (perhaps there will be other suggestions as well) but I
just wanted to get a little feed back on this.
I am roasting in the RK drum.  I have roasted the Yemen sanani and
sarashi several times now.  The roasts were all too dark, except for
one that was under roasted.  I am having a lot of trouble finding that
sweet spot with these beans.
I wait until I hear a good rolling first crack going, within about 30
seconds of getting into a rolling first crack, I turn the tempature
all the way down, and open the lid part way.  I then allow it to roast
for about another 1.5 minutes.  For a total of about 2 minutes into
second crack.  I pull it and start cooking it quickly with a fan
setup.
When I follow this procedure for other coffees, like the Mexican OP,
they look wonderful.  I have tried getting into fist, then pulling the
yemen, just once I got into rolling crack, but then it looked
under-roasted to me.  I took a video of my roasting setup and showed
what the roasted beans look like, I am uploading the video right now,
and I will reply with a link to it once it is uploaded and available
online.
The next thing I am going to try is to go 60 seconds into rolling
first and see if that looks better.  I've been doing 2 pound batches
to keep the results consistent, with the cost of the Yemens, it is
getting a bit frustrating that they are not turning out well.
Thanks in advance for any suggestions.

Yemen is turning out.
Thanks

Jamie,
How did the "too light" batch taste?  Yemens tend to roast up unevenly.
They're never going to look nice and even like the XO.  The proof of the
pudding is in the eating, however, so grind it up and let us know.

Sorry, when I said, "XO", I was referring to the Mexican.

My last one turned out very similar (to the light roast, not the dark!);
One thing I use to gauge the EOR is the expansion of the beans - one  
thing I can do in the iRoast since the level is easy to watch through  
the glass. I may try to go a little further next time; I think I was  
going based on temperature on the last roast, watching it climb, then  
start climbing really quick, when I terminated the roast.
Still, it's quite nice, and that's what matters :)
Try it as an SO shot. Mmmm.

Jamie. Maybe I misunderstand, but you say you are roasting 2 minutes into 2nd crack and it is too dark. Now you are thinking of roasting 1 minute into 1st crack for a lighter roast. That is a huge bracket! The whole range of viable roasts fits within that span, with room to spare. Is there a typo in there somewhere?

Typo...  Sorry.  2 minutes into 1st Crack.   So once I hear the
rolling 1st crack, I go 2 more minutes.
As far as I can tell / can understand, I am not normally going into
second crack with most of the beans.
However, perhaps with the yemens I am coasting right through 1st into
second without knowing it?
With my yemen being so dark, I would almost think that they have to
have hit second crack?

8) From: Andy Thomas
I've never used a RK Drum, so it's hard for me to guess what might be happening. I roast Yemens to the very beginning of 2nd crack -- in a popper -- and they do not taste over-roasted to me. How does your roast of Yemens compare to other dry processed coffee? Are you sure the roast is the problem? Maybe there is something about the Yemen that you don't care for. Dunno...just thinking out loud ...

I am not sure if you saw the little video I made.  This is the Mexican
that I roasted today:http://www.sweetmarias.com/coffee.central.mexico.htmlIt is a DP and it is excellent, it turns out very well.
When I roast the Mexican listed above in the same manner as the yemen
(2 minutes into 1st) it is wonderful.  Looks wonderful to me and
tastes wonderful, same story with the Sweet Yellow from Daterra farms
http://www.sweetmarias.com/coffee.southamr.brasil.html#Daterra_Yellow_Bourbon).It is just the Yemen coffees that I can't seem to get quite right.
I will have to do some more sampling tomorrow of the yemen roasts and
see how the darker one tastes compared to the lighter one.
Thanks

10) From: Bill
I'm curious about Kris's question: how did the beans taste?  You said that
the lighter roast looked too light... how'd it taste?  I am drinking some
ugly colombian cerulean warbler that is patchy, mottled, and very light
brown.  But, as Tom says, I don't put the beans on my eyes.  In the cup it's
great!  So tell us how the lighter roasted yemens tasted.
Second, how much rest are we talking about with those yemens?  One thing
about the DPs is that rest is a real factor.
let's keep working on this one.

I will do some more taste tests in the morning.  This afternoon I was
roasting the yemen to send to my aunt for her birthday, and I was kind
of hung up on the way the beans were looking.  I didn't want it to
look that dark at all, because she really like the "light" roasts that
I do.  So perhaps even thought it looks really dark, it isn't. ?
I've been drinking the Daterra Farms YB the last 5 days or so, it is
really a nice coffee.  Time to switch back to yemen.
<Snip>
I have both some light and some what I consider dark roasted yemens on
my counter, that have both been roasted about 10 days ago.  I think
that is more than enough rest time, hopefully not too much.
I will report back tomorrow after 3 or 4 double shots of the yemen.

12) From: Tom Ulmer
I roast in a solid drum so I probably compensate for a little more heat
retention...
If I understand you correctly, my first suggestion would be to try and stall
the temperature rise just before first for a bit and ease your way into it
then stretch the time to second to 4-5 minutes. At a solid indication that
second is beginning pull the roast and quickly cool.

13) From: Tom & Maria - Sweet Maria's Coffee
this is a good technique in order to keep 1st crack under control, 
and to avoid racing from 1st crack to 2nd crack. You are correct that 
Yemeni coffees are especially susceptible to passing from 1st to 2nd 
crack with little pause, unless you manipulate the heat a bit. The 
danger is of you drop the heat too muc. you never want to stall the 
roast - you need it tom continuously move forward, just at a slower 
pace at certian times in the roast...

14) From: Jamie Dolan
Thank you to both Toms for the suggestions.
Yesterday I had the Yemen roast that was on the light side, and it was
really pretty good, I still think after drinking it that it was a
little under roasted, but not bad.  Today I started on the dark Yemen,
well I can describe it in one word: StarBucks (or is that two words).
It is really way too done, I am going to have to dump it out of my
grinder and will have to donate it.  Luckily my dad is willing to
drink my roasting mistakes, he just makes watered down coffee, LOL!
Thanks again, I am looking forward to trying another roast with the
suggestions provided to see if I can hit a roast level that is
somewhere in between what I have been getting.

I just noticed the grammatical quandary-
"...I can describe it in one word: StarBucks (or is that two words)."
The appropriate contraction would be: "S'ucks." One correct 5 letter word.
