Natural processed Yirgacheffe is DaBomb! So much complexity and flavor notes in one cup! There are layers of depth to unravel! The acidity is pure apple vinegar! Chocolate red wine dipped in earl gray tea that is how I describe in my palate! Mellow sweetness! Medium light roasted coffee will achieve such perfection! Even the ground coffee smell good! Floral scent with hint of sweet caramel! The washed process is also good but not as good as the natural process. It’s very clean, lacks the complexity! The fermentation found in the natural processed bean really gave the illusion of alcohol but you know there’s no alcohol in it. The vinegar acidity is giving that effect!

Did exactly that dropped it when I liked the color 40sec-FC @190.5c

[@alittlerandrplus2]

Thank you for your openness and willingness to share with us. We seem to be on the same frustrating and wonderful path... Instead of dropping sooner, as you proposed, keep the time from FC to end the same, but change the temperature in which it ends. Bring it down a few degrees? Anyway, my two cents. Have fun!

[@BLKCITYCOFFEEROASTERS]

Yea definitely it has to be under 400 I think. Way too toasty

[@YLLUMBUSH23]

Hi there, just curious you’re saying you put the air on full setting or high setting for your roaster? I have the same roaster as you (Mill City 1kg??). Full as in 100 or high for you (60-70-80). Thank you!!

[@BLKCITYCOFFEEROASTERS]

Ya high for me would be 80, and full is 100%. But every machine may be a little different. Use the lighter trick to be sure 👍🏽

[@erharddinges8855]

Feel very encouraged- must buy Yirga Cheffe soon! Wouldyou like to share your tasting impressions? What could be a real indication for a soak? Still do not know. Thanks!

[@BLKCITYCOFFEEROASTERS]

Well The only reason I read was to do a soak for smaller machines. I’ll research more and share later.

[@overthetopblues]

Hey BLK!! I know this is an older video, but a question for you, please. I've roasted this one three times today, and I'm not able to get to FC before 400f and my drop temp was 413, 421, and 426f Charging 380f g to y at 5min 300f FC at 8:35 with 406f and drop at 9:55 and 421f If I was to lower my charge weight would that give me more control, or would you raise the charge temp? HELP please!!! haha

[@BLKCITYCOFFEEROASTERS]

Hey! Sure some context tho: what machine are you roasting on, batch size, what kind of green including origin, elevation, and process? Just want to answer how I would actually approach it

[@overthetopblues]

Thank you so much for getting back. I sent you a message on IG as It’s probably easier to explain my set up. I sent the message but forgot to add the pictures. That’s probably because I was up until 3 AM. Roasting seven batches of coffee!😅 ha ha

[@JohnDoe-ss7pi]

Another good one that i refer back to for use. I know by now you've mastered the Yirg. Would yoy mind sending me your up to date roasting profile for this bean? Ive been playing it by sight thus far and I've roasted about 15 batches ad a beginner since 2 weeks ago. I think I've been doing pretty well. Im just starting to tinker with the Artisan software.

[@BLKCITYCOFFEEROASTERS]

Sure thing! I’ll try to update the one on the site. We’re going to run out next month so I’ll plan making everything live forever in a blog post or something.

[@jacobmiller2050]

Nice video! Did you adjust any settings on roast path to smooth the ROR curve out?

[@BLKCITYCOFFEEROASTERS]

I have a minimal amount of smoothing.

[@jacobmiller2050]

Okay So this is very interesting to me. I recently read Rao's 2nd book and the way I took it is that to avoid the ROR crash, a roaster should raise air and lower gas about 1-2min before first crack. I have experimented with this and have gotten better ROR curves after 1st crack but I am struggling to reach a final BT. The Beans will basically stop roasting and I fall short of my desired final BT. You mention in this video that to combat a crashing ROR you raise your gas. This is very interesting to me, I will have to give this a shot. Are you still roasting this way?

[@BLKCITYCOFFEEROASTERS]

Yep pretty much. But remember whatever you do , just make sure it’s works for you and you’re consistent. Rules are just guidelines really.

[@jacobmiller2050]

@@BLKCITYCOFFEEROASTERS Ill try it out and see what I think! Roasting on the same machine you have
