Hi Mal, from the 2.5kg mystery bag, I tested 2 batches of 350g each in the BM, leaving me with 3 x 600g (actually quite a bit more - thanks Andy) batches for final roast, one for each class (tight azz - no room for error). I had guessed that the beans were Ethiopian or similar, from the greens, so sort of already had a profile in mind - got lucky with that I spose. From the results of the more developed sample to the lesser, decided on a profile (from my previously saved prifiles) for each entry type and went for it, roasting 600g at a time as per class. The 350g roasts were only used to guide me, so I could not use the end profiles I got from those, as it was all by senses, I let the bean speak, my first 12 months roasting was with a colander and wooden spoon - sans temperature readings. It seems to have worked. When I soon boot the roasting PC up I'll post the csv and jpeg. My filter profile obviously could do with a tweak. I did no pre-roast bean prep, post roast was about 5 interloping looking types per batch that got ousted. Definatetly will be doing it again and will use the same or very similar method.
I also have the "big loaf" and have been considering whether it would be possible to fabricate a divider between the stirrers for smaller batches. I've been using a behmor, which is wonderful but do miss the flexibility of the corretto.

Something that can do a good job with ~400g batches would be the sweet spot I reckon.
Nothing wrong with the Behmor though...
I used to run 350g batches of each bean and then post blend. Worked out well for me then but using the Behmor just became too difficult for me to manage. With my useless hands, poor coordination and lack of strength, I nearly dropped the Behmor a couple of times on to a concrete floor. Decided it just wasn't safe around me any more, so headed back to the Corretto. Which if I drop something, won't matter so much...
Another CSer bought the Behmor so it is still in the community...

Congratulations Richard, David and Stephen! Particularly the 70 point latte Richard!
As always great competition! Great opportunity to get feed back, and learn more and keep improving.
Thanks heaps once again to Andy for making it happen and for providing the delicious bean! Well done with your medals.
Got my score sheets back already!
Some useful comments thanks again to all involved and Andy for posting them out so quick.
