Just got my Behmor 1600 and 8lb samples with it.

Trying different kinds and this one completely puzzled me. Out of the bag it's not green, but more like yellow-ish. Smells sour even green.
When roasted smells OK I guess but coffee undrinkable. I tried light and dark. And also I'm beginner other beans were OK/good. Those are really bad. Very acid/sour tasting.

Is it coffee kind or bad beans?

I'm talking about Sumatra Mandheling-Aceh Triple Pick

To answer your question: YES. A resounding YES. But the question of whether or not YOUR coffee is bad is another matter entirely. And for that, you will need a palette you can trust, a sample roast, and some cupping equipment.

But really, it's not all that complicated. You're new to the roasting game, so mess around a little with it. If you can't get anything "drinkable," then they're probably pretty rough greens. Where did you get them from?

Probably I wasn't clear. I do get decent results with other coffees. It's only this one that really bad. I just don't know if it's type of coffee or those beans is bad.

I'd go back to the supplier.  It's very likely you got a bad bag of greens, probably slightly fermented.  I've roasted a Sumatra Mandheling and it's definitely not sour.  (My supplier may or may not be yours, but I'd not expect *that* great a difference.)

A good supplier will take care of you.

I am sort of uncomfortable writing this but I am afraid you may have been sent an iffy or perhaps old "green". I would have expected an Aceh triple pick to be a nice looking coffee and not yellow. A well respected company, which I will not name, is doing a promotion to sell their overstocked coffees. I notice as part of their sale is a Sumatran Aceh triple pick but it is NOT listed in their listing of Sumatran coffees. I kinda suspect they may be getting rid of the bottom of an old bag. Certainly if you paid for the coffee and it was not thrown in as a bonus I would inquire if you could send it back and switch to something you like. If it was thrown in as a bonus and not paid for I might suggest just adding the experience to your coffee learning curve.

Happy roasting, Skylar

Yes, this is what it was. Part of a sample from SM when I bought Behmor. I guess it will be part of learning. So, should I "remember" those hints as a bad coffee I guess?
It is definitely not right.

Any reputable bean supplier is going to want to hear about bad beans going out so that they can do a quality check on what they have left -- even if the bag was part of a "free" sampler.  Suppliers don't get repeat business by sending out sub-par goods.

I'd definitely inform SM (nicely!) so that they can take whatever action they feel is appropriate.  They can't fix what they don't know is broken.

I will send them letter. I think it is good lesson for ME so I can tell the difference. Today I roasted 2 other samples and they both taste excellent, so it is definitely beans.

I have no hard feelings, I got 8lb of samples with machine, so it's no biggie. But yes, for future customers I will let them know, also this coffe NA on website.

If lactobacilli gets into the fermentation process, then the beans can definitely go bad. You will probably get a distinct sour taste to the coffee. I had some tanzanian from SM that had the same problem. Nothing to do with the roasting process.

SM's are way above reputable, so I'd just write them a letter, or even an email will do.
Neither Tom nor Maria pack bags, that's done by workers.

I can assure you, at least from MY experience that this was not deliberate.
You can order from them with confidence.
Same with dozens of other guys we all purchase from.
