Hi All, I've been experimenting with some devices to roast larger batches (1 lb +). E.g., I rigged up an old bread machine. It managed to get to a good Full City roast level, but took a long time doing it (about 45 minutes). How long is too long for a roast? Is 45-60 minutes for a batch too long? Most profiles I've seen seem to be in the 10-20 minute range. I expect there's a good reason for that. Any thoughts on really long roasts?

<Snip> My longest drum roast was 29 minutes and resulted in very good flavors, but no brightness. Lack of brightness/acidity is the main problem with long roast times. Also, poor control may let the bean temperature fall, and this can result in a significant loss of flavor. It may also create some unpleasant flavors. Most of my roasts are in the 20 minute range, but a lot of this time is spent in heatup and drying. My profile times after the bean temperature rises above 125C (257F) are about 8 to 12 minutes for a city roast. You need to reduce your roast time, either by adding more heat or using less beans. Good mixing is important to prevent scorching and provide a more even roast. --
With a heat gun in my wife's deep Kitchen Aid mixer bowl, 800g was too much for Glorious Orange HG with switch. I was at 15 minutes, just starting to get 1st Crack! 1st was done about 25 minutes in, and I couldn't coax any beans to 2nd. No smoke, so I had a nice origin flavor- just barely a City- on the Panama Berlina. The popper or Fresh Roast could top it off if I wanted to scorch it more on a brew-by-brew basis. I didn't and I won't do that much again. I think excessively long heating drives out the moisture that retards smoke and causes the beans to pop and snap. Popcorn won't pop if it gets too dry.

I wouldn't keep using the mixer bowl since roasting in it will permanently stain the bowl. Your wife may not be too happy with you! Sheila raymanowen wrote: <Snip>
I agree, Ray. In fact, if she isn't aware of your *ahem*, experiment - I'd hide that heat gun pronto (before she decides that it would also serve as a useful weapon!!!! ; > ) Lynne On Nov 19, 2006, at 3:07 PM, Sheila Quinn wrote: <Snip>
