Roasted my first sample of the Rwanda this morning in the popper, as a test, and wanted to report results. I like the way this particular Poppery II roasts, a little slower than some of the others. It took 6:30 to the start first crack, and first crack ended about 7:00, and I stopped the roast at 7:30. City roast was my goal, and this is pretty close.
Ground and brewed right away (because we were out of roasted coffee!!!)
Grounds did not have the usual hint of 'this coffee needs more rest' kind of green-ness, rather gave a sharp, lovely, apricot or apple kind of aroma. In the cup I'm sipping kind of a pineapple caramel sweetness, lots of florals, and maybe a little butterscotch. As it cools, some mandarin tart orange shows up just a little bit. It has a solid body and a lingering lightly sweet, dark caramelized sugar.
Now, when you read this, what I'm really thinking is, "this coffee tastes really good, especially with no rest at all." Then I sip and slurp and close my eyes and try to figure out what those good flavors are, or what they remind me of. Your experience will vary. It was supposed to have orange, vanilla and raspberry, and I definitely get vanilla, and perhaps the pineapple is a combo of orange and raspberry? Who knows. It tastes good though!

Don't put the cart before the horse. Put the horse in the cart and listen to him say "weeeee" all the way down the hill.

Chad,
Just finished the first roast and if I can go by color, to about the same degree as shown in your post. I've been reading the Willem Boot articles so first I grabbed a handful to assess moisture content, guessed about 13%
On that assumption and Willem's advice I gave it a little bit of a slower drying phase to yellow, then pushed at about 30F RoR to 1C, dropped to 5F RoR for 3M and dumped at 12M. The roasting aromas were very fruity with no "wood" type smell. I will wait 2 days if I can. I think the Rwandan is even more aromatic than your Ethiopian A1 Harrar if that's possible. Outstanding!
Thanks,
Mark

IMHO, don't wait!
I roasted another test batch, this time to 8:30 in the popper. After first crack I sniffed aromas constantly until I discerned a hint of change, then stopped the roast. This time approaching Full City (but with no signs of second crack). I will say it has lost much of those aromas!
Keep this one light as practical for your roaster.

I roasted 2 pounds of it yesterday. It dries very quickly,I was using my data from a Peru SHG, I pulled the first first pound at 12 minutes, and it looks like Starbucks. I stopped the second batch at 10 minutes and its a a nice full-city.
I plan to dry at 900 watts instead of 1200 watts next time.
.
I sampled a taste this AM:
I'm NOT a cupper, but...sorgummmm....

So got my stash on Wednesday roasted yesterday.
If I did not know the origin looking at the beans and the way they roast, I would have guessed a Kenya?
12 hour rest and about the same as you Chad maybe a little darker?
This was a slow roast 6 min to dry, 6 to change color, 3+ for the 1st crack.
Not a very strong aroma from the grounds just earth and chocolate.
Cup smells like a Yemen somewhat, dark chocolate, caramel and slightly floral.
Taste is very complex up front a sort of caramel-date sweetness.
In the middle earthy and dark chocolate flavors.
Big juicy body on this one. The end haunts your palate coating and lingering like a Yemen. There some other light fruit flavor but I just can't describe it? Yum think I'll have another.
Thanks Chad I look forward to playing with this one!
Glad I got 10lbs.
Well now........ that's not suppose to happen!

I roasted a couple batches yesterday. Today I drank one taken to full city with a single audible second crack before a 1 minute cool.
And it's different. Chewed, warm, beans were really I tense and roasty. Definitely bittersweet is the predominant note I picked up. I got no fresh fruit or berries and I was just a bit dissatisfied. However, in the cup after a 16 hour rest, the FC roast (EDIT : juat realized this report is for the C+ roast. Derp.) is worlds better than I imagined yesterday. It honestly reminds me of a Sumatran on steroids. There's more body and acidity but the same earthiness and toasted flavors are present. These are not flavors my roaster highlights, so to find so much of them tells me it's it's the bean. FYI, I love Sumatrans and I love body so this is a big win for me. i definitely need to work on the profiling more to coax out any nuanced flavors present but I think all in all I'm going to really enjoy this lot. I did fond a lot of beans with one end crusty and eroded which I find in a lot of Sumatran. I did not pre-roast cull these. I had zero quakers out of five ounces I roasted. The beans have a pretty uniform appearance after roasting, much more than Kenyans I've had, and there is significant size differences between beans. Post-roast, I measured beans ranging from 5-16mm and everything in between. I wonder if the small beans roasting faster accounts for the I tense roasted flavors in the cup. I will grade one pound into three sizes and roast to similar levels and see.
I'll brew up the one taken at city+ and see how it compares. I didn't fond any of the fruit Chad found but also see his note to go light as possible. maybe I'll fond it in that cup.
My profiles were
city+ : preheat to 375, drop load, temp sank to 230, 4 minutes to 305, 5 to 380, first crack at 9:02, ends at 10:15 temp of 396, ROR 6/min to finish at 12:35 with no second cracks, dump and cool quickly.
FC : preheat to 360, drop load, temp sank to 220, 4:25 to 320, 4:35 to 381, first crack at 8:59, ended 11:08 temp of 390, ROR 7/min to 408, ROR 3/min to 417, second crack, dump and cool quickly.
Note all temps from a ss probe which only sees bean contact after first crack when expansion sets in.
Thanks Chad so far I like this lot.

Ok now I had to brew up the FC 
I like it better . It is syrupy and thick and the taste lasts forever. Their is simply a ton of sugars in these beans. And a great balance of acidity on this roast. This is not a flat coffee at all. I'm getting true cinnamon, bergamot, unripe plum and apricot jam, grape skin,and blackstrap molasses. The flavor opened up considerably after cooling to a temperature around 115. Im still finding more similarities to the Indian and Sumatran coffees I've roasted than the NE Africans, but I'm pretty inexperienced for what it's worth. J |

Roasted two pounds last night in the regular air roaster. I tried real hard to keep it fast like my first popper roast. 9:20 to 423F. Something is different though. Florals are there. Butterscotch is there. Aahh, the difference: the pineapple has been roasted on the BBQ. Maybe temps too high and slightly scorched? Dunno, but it's dang good as it is, just not quite as snappy.

I did a Rwanda roast today on the Turbo Crazy and new control of the heater with a SSR and Cataui. Went about 2 /12 minutes after 1C with a steady RoR. Warmer today in the garage 50F. Looks good will see tomorrow how it tastes. Click on the image for a larger view.

This bean appears to roast very quickly, at least in my roaster, thought I messed it up trying to slow down as it went far faster than my three prior roasts (did a marathon roast, started with columbian, then sumatran, yirg,and ended with rwandan). 8'30" to FC, pulled at 9'30". Per recommendations here, I didn't wait and made myself a cup about an hour later, and wow, it was very different: someone above wrote "a lot of sugars". I agree! It's dark, too, is that "earthy" ? |

Roasted 3 - 1/2 lb batches yesterday. City+, full City and light vienna. Cupped them this morning, though I was a bit hurried in my effort, was VERY happy with the results. The rest was about 15 hours or so. The City roast was the most developed of the three, though none were bad roasts. Definitely caramel, maybe light molasses flavor in the background, even for the city+. Definitely floral in the aroma with what I thought was some citrus notes.
The FC and Vienna need another day of rest, maybe 2. Once I think they have hit their peak, I will try and remember to post some notes.
Here is my profile for the City Roast in Celsius.
Pre-heat: 150
1:00 - 120
2:00 - 160
3:00 - 176
4:00 - 184
5:00 - 192
6:00 - 205
7:00 - 214 1C Start
8:00 - 220 1C ended 8:05
9:00 - 224
10:00 - 229
Dropped |

I never tasted coffee with such residual sweetness. I didn't get a lot of fruitiness at City+ but maybe the best lingering flavor I've had. Thanks Chad |

Interesting article from Sweet Marias about stretching the roast and they use a Rwanda coffee for the test. http://www.sweetm.../node/2934
To me, this coffee is very similar to Burundi. I am getting a strong cocoa flavor after 2 days rest. I am not very good at picking out the flavors, but I thought the molasses was stronger after the first day, then seemed to turn to a more dark cocoa.

Drinking some this morning after ~15 hours rest and it is good. I'm sure it will be even better tomorrow. Still trying to wrap my arms around roasting these small beans. I thought I had really over roasted this batch, but apparently not. Gonna try a different profile next batch and try to slow things down.

OK, here's my effort. I'm new to all of this and very used to overly roasted coffee. I'm not sure if my taste buds understand lighter roasted fruity coffee. I'm roasting using my newly converted BM/HG roaster (which i really like BTW), but without any temp monitoring in place yet.
Here's what I came up with:
Both batches were 540grams and the temp in my garage was in the low 40's.
I went full HG until middle of FC and then dropped back to low for the remainder of the roast.
Both were cooled in about 1.5 minutes. The picture is of batch #2, but they both look about the same. I think I hit about a City + if I'm getting it right.
Batch #1:
8:20 - FC
9:50 - FC Ends
12:30 - Drop (no 2nd crack sounds)
Batch #2:
9:30 - FC
11:00 - FC Ends
13:30 - Drop (no 2nd crack sounds)
After about 15 hours rest, I made a cup of each this morning.
Batch #1 is very bright, but definitely has an orange/citrus quality to it. The body is light and the finish is long with a tartness to it that wasn't foul but not sure I liked it. Overall not bad, but I'm not sur this flavor is what I like.
Batch #2 The same bright notes were present but mellowed a bit. Overall, the cup seemed more balanced and had a bit more cocoa/caramel flavor going on which helped with the brightness. Finish is similart to #1 but the tartness was more subdued. Much better to my tastes, but not sure if I'm just used to more roast in the cup.

Interesting how most of us are hitting first crack between 8'30" and 9'30". For those of you letting a light roast rest.. next batch, try brewing a cup within a few hours of the roast without rest as suggested by Chad.. it's unbelievable. :) Those new roast flavors seem to mute with rest. |

Great discussion all! I believe this illustrates the 'art' of roasting coffee. Now, when I say 'art' some of us read 'correct way'. But, no! When I say 'art' I mean it like Picasso or Hendrix or Hawthorne.
