Subject: What is an even roast?
 

I'm curious what an even roast is supposed to look like. Given different bean sizes in blends, will all end up the same color? I'm attaching a picture of my most recent roast of El Competidor from SW (FC+?) and it looks like many of my roasts recently, with some beans lighter or darker than others. Is this even? If not, what am I doing wrong? I'm roasting on a Behmor on P3 at the 1lb setting (though only roasting half a pound).

I gather that you meant "SM" (Sweet Maria's) rather than SW. I also gather that El Competidor was a blend SM sold. If so, as a blend, you will get some uneven roast colors, as there are beans of varying densities, water content, etc. in the mix.

If you want to see a single origin bean that roasts very unevenly, see this thread at SM's site.

Also see this thread about roasting blends with the Behmor.

I recently acquired some Ethiopia Gr. 1 DP Yirga Cheffe Kochere from Sweet Maria's which has a bit of color through the greens I haven't seen in other varietals from them.  They do color differently on roast too.

By the visual I would say you have a City roast, possibly City+.  But definitely not a Full City+.

Yes and yes. Thanks for the links. They're a great help.

Thanks. The pic makes it look much lighter than it is. Sometimes I'm afraid I'm going to far into second crack, but lately I've wondered if I'm even hitting it. Is 2C much different from 1C in sound? I don't want to burn, and sometimes I go we'll over 3 min after first crack. But maybe what I'm thinking is 2C is actually just more 1C....

Yes 2C is pretty much unmistakable. Sounds like snapping toothpicks. Keep in mind that 2C will look pretty dark and soon after the beans will begin to shine (Vienna roast).  P3-5 on the Behmor are lower heat profiles meaning longer roasts before hitting 2C.  I use P1 and P2 for med to dark roasts and P3-5 for quality lighter roasts.  
As for blending uneven roasts will always happen unless you are blending all hard or soft beans.  If you were to blend and use say P5+D profile you may see a more even roast.

I don't know about the odors a Behmor produces. With my HotTop I've only roasted outside, and have recently given over using the filter assembly they provide as nothing so much as a damper... what I notice when I'm starting strongly into second crack in the exhaust smoke is a more acrid note.  My nose is becoming sensitive to notice when I start leaving the land of smooth caramels and start the driest beans giving up their oils to flash off and cause the odor of the smoke to change.  This can be ahead of when your ear tells you second is occurring - in my case due to the nearness of the drum rolling beans to that early sound of 2C.  Your experience may vary especially with a machine designed to allow in the home environment roasting.  And yes, first crack is a resounding statico pop, while second is definitly the sense of dry wood snapping rapidly, albeit quieter than 1st C.

The Behmor like any roaster has a good deal of odor because the afterburner is only getting rid of most of the smoke.  I use a fan pointing outside which gets rid of the smoke completely as well as 80-90% or the odor.

Tyler,

It is very common for blends to be uneven in color from bean to bean.  Many things affect two different beans from having the same final color when roasted together under the same conditions and to the same drop time/temp.  Things like bean density, variety, sugar content, processing and age to name a few off the top of my head.  

Roast color variation is definitely more noticeable in lighter roast profiles where the woody structure of the bean has yet to carbonize (burn).  I would also say in general wet-hulled process coffees tend towards the most variation even within "Single Origin" lots.  In reality, most "Single Origin" lots are made up of multiple coffee varieties grown on multiple farms on multiple altitudes, so it is not uncommon to find color variation present in them.
