Ethiopian Yirgacheffe Grade 3 Dry Process! Roasted FC. We'll see....described as a bold fruit forward cup! Right up my alley!:)

Give that Ethiopian Yirgacheffe time to de gas
I would say a minimum of about 10 + days or it will kill a few taste buds on the way down Grin

Good lord! 10 days? That would kill me!:)
I've been waiting 4 and 5 days for Ethiopians lately. How is it even possible that gas is still coming out of that tiny bean 10 days later? Would you say 10 days for all Ethiopians? The misty valley I roasted was very nice @4 days, but tasted flat and lifeless @ 10 days....

Hmm... what to roast today? I'll be out of fresh roast in about 3 days, so...

El Salvador - to start drinking in 3 days
*and*
Red Sea Blend - to start drinking in 10 days or so when the El Salvador has been consumed.

10 days seems a bit long to me as well. I find the fruits peak at about 4-5 day in my Ethiopia roasts.

I forget, what are you roasting with, KK?

10 days rest post roast for most African beans is the norm but I normally roast them to just past 2nd crack

Today's Roast
600gr Sumatra Panjang Mandheling

The bean sellers notes for this bean is

Quote

Sumatra Panjang Mandheling. Translucent blue/green in colour with a golden layer of chaff this wet hulled Mandheling produces huge body and liquid chocolate type pours ooze from the group handle. Deep, rich and earthy without the funk sometimes associated to some Sumartran coffees. Great as a single origin at CS9-10 roast depth or add a higher acidity bean to make an excellent espresso blend.

Isn't the beginning of second crack a full city plus roast?

Here's the guide I've been using from Sweet Maria's http://www.sweetm...uideV2.php

Now then, our own home page says the beginning of second is full city.

Which is it? Help me out.

Well, so much for standards, eh? There's inch, there's metric, there's metric tonne... Interesting.

I wonder, KK, if there's a temperature chart to go with the color chart. Is the number system pretty widely accepted throughout the country? or is it more specific to coffeesnobs.com

Now this is fun. And most interesting.

We have a guide
FC between 9 to 12 min depending on the bean @ 195 to 205 deg Celsius + 6 min to SC @ 218 to 222 deg Celsius

Well that's how I understand it to be

As to the number to color system I think its mainly coffee snobs that do it

Do you mean the 7th image from the left is First Crack and the ninth image is Second Crack? Those look dark to me. I would expect First Crack about 5 and Second Crack about 8.

And if I had to put temperatures to these images (viewed on a Dell Lattitude E6400), I'd guess
1-green
2-200F (95C)
3-300F (150C)
4-375F (190C)
5-400F (205C)
6-415F (212C)
7-425F (218C)
8-435F (224C)
9-440F (227C)
10-445F (229C)
11-450F (232C)
12-460F (238C)

All in the eye of the beholder.

The great thing about standards, is that there are so many to choose from! :-)

KK...I gotta give it to you. You were on the money with this coffee! It has been taking taste buds down every couple of days I would sample it. I roasted it on 10/30. This morning...9 days later... it has finally mellowed and no longer has the dry process funk flavor. I'm still not getting potent fruits, but it does have a banana flavor now.

About to roast some India Robusta from SM. Supposed to be a very nice cup. Never roasted a robusta before. SM's says to roast into C2. Anybody got any advice or experience they can lend?

Robusta is easier to roast than Arabica
No change required in technique

You will notice the roast colour to be very even on Robusta

OK...that was weird!
One snap of C1 and I waited for it to "really" start......and waited.....and finally dropped the temp as the color was getting really dark and I figured I must have missed it. Ended @ onset of C2, which was audible and acted normal. Also...chaff did not come off as neatly as most arabicas. Had to pull off a bunch by hand after roast.
Anyways...that's why I got some...to experience something different.
