Posted Sat Jun 15, 2013, 3:08pm Subject: chaff stays in the groove?
just roasted up a cup (volume of greens, pre-roast), of Ethiopia Organic Suke Quto, an SO, from SM.
Anyhow, this time I didn't pay much attention to the cracks, (distracted with 3 year old girl), so I went mostly by looking and time roasting.
Post-roast, the beans are dark and small, darker than the dark rich carmel of a FC+. The thing is, they are _behaving_ as if the are under roasted. The flavor is VERY bright, a 19 gram dose still under-fills the 18g portafilter basket (as you might expect from a very light roast), YET: they _look_ very dark... only not the least bit oily. But worst of all, there remains a thin "rib" of chaff in the groove of almost every bean.
So many things not quite right about this, that I don't know where to start, in diagnosing the problems with the roast. Any help/suggestions?
The roaster is a Cafe Rosto I've been using for years. It's basically like an air popper only way more robust, purpose built for roasting coffee, with a chaff trap and cooldown cycle.

My first thought was that it sounds like the results of a super fast roast. Other than that I don't know, is that you're typical batch size? Anything else that could have happened while watching the little one? One other possibility you probably don't want to hear- maybe your roaster is on the way out. My Freshroast gave me some whacky roasts on the way out- ever consider putting together a SC/TO?
