Today I tried to increase the batch-size of my roasts again. After getting new greens from the Roestbar in Muenster (imported by InterAmerican Coffee, the bags say 'Yirgacheffe' and 'Kenya AA' ). So, I went with 500g green beans, and the cover of my cast iron thingy open.
Everything went really well, roasted a blend of 60% Yirg and 40% Java, until ... well, right as second crack began to get audible I heard a loud, and I mean really loud BEEEEP BEEEEEP BEEEEEP BEEEEEP that scared the hell out of me because I didn knew what it was!
Took me a few seconds to figure out it was the smoke detector in the corridor. I was very lucky to have a friend with me 'cause he stirred on while I tried to disarm that damn loud neighbour waking alarm!
Now I have a very dark roast and my heart is just recovering from the shock. But hey, I can evenly roast 500g batches in 18 minutes
