I have been using a corretto for ages and do 625g green batches to give half a kilo roasted. I have always loved drinking the results.
A colleague got a behmor and roasts on auto. When he gives me his beans the taste seems more complex and full. I could definitely notice the difference each time I have tried his beans.
I now have a behmor and am learning to understand it, as Mal said its a different sort of operation and I miss watching the roast profile through the data logger. I look forward to nailing the results.
Also, the behmor is much more of a "clean" operation, much less franken style than the corretto. You load the beans and insert the drum and chuff tray and it stays there until done. Simples.
