Before roasting green beans at home, read some useful tips to make it perfect:
1.Look - the appearance of the bean will change through the roasting process. Its color, size and texture should be watched carefully.
2.Listen - two distinct popping sessions are heard during coffee roasting. These are known as the first and second 'crack'.
3.Smell - the beans will smell differently at each stage of the roasting process. The aroma should be used in conjunction with appearance of the bean to evaluate the stage of the roast.

Funny enough I was just reading a blog where the writer said you can start home roasting with the minimum of equipment. I am interested in giving this a try but need to read more. The changing smells idea is intriguing - perhaps best not to attempt this when you have a cold!

I consider that it is not ewarding work! As if you grow up at house lemon tree. It is a lot of efforts, and the result is not considerable.

Thanks for sharing these tips, jesse! Very useful. I never heard of first and second 'crack'! Must check it myself

Yeah, lol! You should avoid any different flavors when you trying to roast your coffee at home though I don't quite understand how is it possible - when you have full house of living organisms who smell themselves
