Going darker with a washed Ethiopian coffee I've never roasted before (on the Loring S35 roaster)

This is my approach to taking a washed Ethiopian coffee to a "medium-dark" roast level, end temp of 428+F, which is darker than most of the coffee I normally roast.
It's a 65lb batch on the 35kg Loring roaster.
*NOTE: This video is relatively advanced, assuming previous knowledge of coffee roasting language and concepts. If you're a coffee roaster, I hope this video will be interesting or useful to you. If you are not a coffee roaster, well, I'm sorry if it's confusing or boring.
Questions about this roast or this machine? Adjustments you would have made? Other videos you'd like to see?
Comment below!
Thanks for watching. And happy roasting!

hi Kat, thank you for this first hand experience on Loring. As a Giesen user, it is very interesting to see how precise Loring can do.
Keep it up , i really like this kind of videos. Cheers!!!!

[@roasterkat]

Glad it was helpful! Thanks much

[@meFatuations]

In these videos, I would love to see a shot of what the coffee looks like when it is done roasting. Thanks for the video.

[@roasterkat]

Good idea - thanks for that! I’ll try and add it to future videos.

[@TheDvsdog]

Love these videos.Keep up the good work.i normally like my washed ethiopian medium to light. From a roaster down under 😊

[@roasterkat]

Same - this was for a friend who needed it a bit more “developed” lol

[@MikeTheBlueCow]

You make this look easy!
Awhile back, I was roasting on a FreshRoast SR700 connected to Artisan for logging and controlling the roast. Then my SR700 died 😢. For the short time I had that setup, it was more or less similar for how quickly it could react, just with tiny batches 😅.
When I was taking temps by hand, roasting was so stressful - 8-10 minutes is a very short timeframe to be manually checking temps every 30 seconds and then having to react with changes in fan speed and heat.
I loved watching you work on a much larger, more impressive machine that could be controlled as accurately (and moreso) as my old setup! It's interesting to see how the larger batch really protected the roast from drops in RoR, for my small batches I would have to be so careful not to over adjust - lots of small, frequent adjustments.

[@roasterkat]

For sure - different machines are super different! There are some coffees I have to be more careful with so they don’t either tank or take off, but this one is pretty even-keeled.
I’ve worked on machines where I had to take manual temps too and gosh if that isn’t a pain, and also a panic! Haha. Glad you had the opportunity to experience it. It’s like nothing else

[@roastedbymom]

This was awesome! I was looking at the graph and trying to figure out the charge temp you started with on this batch … I don’t use Artisan or Cropster cause I roast analog 😂

[@roasterkat]

WOOT! Old school - love to hear it. Are you taking temps every 15/30/60 seconds?

[@roastedbymom]

@@roasterkat visually I am 😂 when I roast dark my temps are: charge @ 370 / RoR @ 160 / @ FC 380 / DT @ 425

[@congbaophan9618]

that's awesome, may I know do you adjust airflow or drum speed while you roast or only adjust burner? Thanks and cheers

[@roasterkat]

On the Loring the gas and airflow are both the burner - so I can only adjust that one variable.

[@congbaophan9618]

@@roasterkat oh great, thank you, so that”s the reason why Loring easier to get consistency in roasting

[@keithstehling3586]

Thanks for the vid. What type of Ethiopian coffee were you roasting?

[@roasterkat]

Washed Ethiopian. I didn’t have any more info than that.

[@youhube100]

Did this curve come with a charge temp you followed or did you choose one based on experience with this size batch and roast level?

[@roasterkat]

I used one that was typical for that batch size and desired end temp

[@jeanfxjeanfx]

I’d like asking you how you apply BBP on tht machine 🎉

[@roasterkat]

I hear you. I’ve started that video a few times and never finished it haha. I’m afraid people will take it as the “only way” to do BBP on Lorings rather than one way. Any ideas on how I can preemptively avoid that?

[@youhube100]

​@roasterkat that's the same disclaimer you'd have to make with every roasting video lol just go for it!
