Profiles for different origins
landon_lion
Got the new B model last week, two roasts so far using Ciel's profile. I've had fantastic results. Really, the yirga cheffe after 48 hours was one of the best cups I've ever had. I'm blown away by this roaster. Coming from a behmor, it's like going from folgers to stumptown. I'm sure I'll eventually put in a bt probe, but I'm happy for now.

So I'm just curious if you all are trying out different profiles for hard/soft beans? Does it make much of a difference in the cup? I usually roast at a city/city+ level, and use various manual methods for brew. Between the Ethiopian and the El Salvador I did last week, the origin flavors coming out are astonishing. I realize there is always room for improvement, though, and I want to keep getting better and understanding more.

Thanks in advance!

Any profile comparisons should only be compared with the same roaster
However one can have differing results ( although close ) as different conditions can affect a roast

That said I love to experiment
So I encourage you to roast away as often as possible and let you taste buds determine your profiles

I believe that we have a spreadsheet of profiles to experiment with in our downloads area

KK, I've consistently gotten very similar results and many times identical from a given profile in totally different drum roaster designs.

From my reading of Landon's post I don't see where he's implying comparing profile results from different roaster types.

High grown beans, Yirgis and El Salvadors are harder more dense than low grown beans. It takes a more aggressive application on heat to get the best flavors. If you roast a low grown bean the same it will burn and be not as good. The low grown beans I run into are Brazil and Kona. Geishas need to be roasted like a soft bean in my opinion. If you look at the crease in the beans you can get a idea of how high it was grown. A open crease would be low and a tight crease would be high.

Thanks, all.

I just finished a 227g batch of Rwanda. I pulled it a bit early, maybe just barely a city roast... barely. 13.5% loss. Oh, well. I hadn't heart that about the low vs high grown opening of the crease either.

I'll check those out in the download section.

The reason I noted close results between same type roasters is due to differing conditions
For example - power fluctuations , ambient temp differences, even at what altitude one lives at can have subtle differences

By all means use any roast profile suggestions as a guide but always trust your taste buds
Happy roasting BBQ grill

Your comments make more sense now.

Using a profile from someone else, even with the same roaster doesn't mean that the profile in your roaster and conditions (humidity, atmospheric pressure etc) is going to necessarily be optimum so be sure and tweak away. Great point! ThumbsUp

I hadn't had any coffee when I read your post which is no-no.
