Tried the Geth in the machine, then tried it again, then again, then a capp, then another capp, then "Oh sh1t it's run out!" Bloody good stuff. No sleep.
Just roasted a 200g batch. Now I hate to sound big headed (!) but I aimed for 1C at 14.00", I hit it at 14.02". This thing is brilliant! Dumped the batch 30 seconds into 2C at 18.30" and it is better looking than the last lot. I think 250g which also happens to be my ideal batch size consumption-wise is going to be even better.
