Thanks Austin. It has been very interesting. I have a student grade colour spectrometer on order to do some roast colour analysis. Looking forward to it arriving

On a personal note I'm glad to see you on.

When you roast coffee, caffeine crystals form on outside parts that the smoke is exposed to.

I wrote an article on 'angel hair' what these crystals are known as.



Here is a picture. In the article on my blog I also have views from a digital microscope.

So that's what I'm addicted huh?

It's good to see it's face.

okay this question may have been answered before but here it goes.. We have recently started a small coffee business. We order green beans and then roast, flavor and grind them. I know you have to degas the roasted beans but iv been told that already ground coffee does not degas. But iv been running into a problem with our ground coffee. The bags do not have 1 way valves on them and they are starting to inflate.. Did i not let our roasted beans degas long enough? Can anybody let me know how to correct the problem.

Ground coffee definitely does degas. If you read my blog at http://coffeetroupe.com/ I did a experiments measuring the degassing. Ground coffee degasses for 24 hours. If you are talking commercially roasted coffee that is high speed roasted in 3 minutes, the will degas almost immediately when ground. Normal roasted ground coffee takes 24 hours.

You could bag, close the top but not seal. The CO2 will be emitted within 24 hours then seal.
