@_Simon_ , hey, have a coffee roasting question. You ever run into beans that are almost too small for the Behmor roaster? I picked up some Ethiopian beans, and they are teeny-tiny. Roasted okay, but several got stuck in the mesh of the roasting bin and a bunch even fell out.
Ahh yep, I have experienced that. Some Ethiopians are seriously so small... I don't think any ever fell through the mesh itself but some certainly do get stuck in the mesh the whole time, which doesn't give those beans a decent roast...
So after the roast when I've dumped the beans, those stuck ones I either throw out, or just eat them hehe.
There are a few times when smaller beans have fallen through the little gap at the actual lid/clasp area, so every time I try to make sure it's closed as much as possible so that none can get through.
And even though it just doesn't feel right to haha, I've been told it's no drama even bending the lid a bit to get it more closed off.
It's only every now and then that beans get through, but yeah I would just make sure the lid is properly closed (at the actual opening area). As for beans getting through the mesh that's a tricky one, and I don't think any other drums are available with a finer/smaller mesh... I would just either screen out yourself which green beans are too small, or just dump those beans that escape unfortunately. Hopefully it isn't too many that escape!
Or what some people do and gather up all the fallen out ones and try brew them up anyway separately. Can be pleasantly surprising haha.
Hope that's of some help!
