    matching roast style to particular beans

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Im a newbie, about to get a Genecafe and can hardly wait. I just got the coffeesnobs starter pack. I understand I need to experiment with different roast darknesses for different beans, but Im wondering if there are guidelines I can look up about what roast style seems to suit particular types of beans? (I make great espresso with my Rocket Giotto, now Ive become obsessed with finding great beans, so thought I better roast my own.)

    Hi Hobart, if you check the cupping section CS roasters usualy compare notes on beans there, usually ones purchased from beanbay, you should be able to get some good pointers from there.
    I tend to roast my beans to just around the second crack mark, I dont like dark roasts, I find if I roast to just on or after second crack the beans natural characteristics come through in the espresso.
    Good luck with your new roasts, Im sure you will get heaps of support from CS roasters.

    Re: matching roast style to particular beans

    The three common ways of using the Gene seem to be:

    1. start at 150 for 5 minutes to dry the bean; 250 until first crack; then back of to 230/235 until rolling crack stops and hold to degree of doneness is there (Second crack or colour)

    2. 250 from start then as above ...

    3. 235 from start until done.

    There are litterally thousands of other combinations, but these seem to be common. As to which suits which depends on the bean and the size of load. Some beans need to be dried, some dont. Best do 100gm of each.

    Keep a note of start and finish weights which is also a measure of doneness

    As a matter of practice, I allways warm the machine up by running it to 100 degrees then cooling before loading any beans, just so all roasts can be compared in profile, and you can re-do the ones that work for you.

    Thank you Greenman!-- I followed your suggestion and got the info I wanted. I also see info in the cupping section on how long people have found best to wait before using particular beans after roasting. Im wondering though if there is any visible or olfactory cue other than just trying the beans to see if they are ready?

    Not really, its all to your taste. Most people end up preferring the coffee between 3 and 14 days, with some (like the Monsooned Malabar or the Yemen) maturing a bit later.

    For temperature, as I have just reported elsewhere, I tried a Gene roast of Malawi beans with a set temp of only 220 and it is now drinking fabulously, 4 days later. It was a slow roast--22 minutes to turn off.
