question on half roasted
« on: February 01, 2012, 08:59:47 AM »
just a quick question for the roasting guru's  :question:
a few days ago i was halfway through a 500gm roast of my kjm style roast , roasting in my breadmaker heat gun setup , i was just at the stage where the beans are starting to go from yellow to a very slight tan tint when my heat gun took an early retirement and threw the towel in ( it was the fourth roast of five for the day , maybe i should give the gun a bit of a break between batches ) anyway now a few days later ( took me a few days to get another heat gun ) can i still roast those half done beans , ? or would it be better just to chuck em out , as in they would not be drinkable , or roast them and then blend them with another 500gm of fresh roast ?
i dont mind if i have to throw them out , would rather do that than roast a batch of rubbish coffee.

Yes you can
You will however need to do a complete or full roast again because the beans will react in the same way as un-roasted beans

The beans will need to be consumed quicker than normal as they loose flavour at a faster rate

I'd finish them off Texx, cant do any harm and you may just be pleasantly surprised, maybe your onto something, guess you could refer to it as roastus interruptus. ;D

I have done something similar with a PNG bean on a Hottop. The beans dumped at the 180deg alarm due to me not being attentive. I allowed them to cool totally then re-roasted them from scratch. I took it a bit a slower in the ramp up to where it was dumped the 1st time, but it then went on pretty much to schedule, looked suprisingly good, and tasted surpisingly good as well. Used in a blend, so not sure if there was any quicker loss of flavour as per KKs observations.
