    surface ripples?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    hey all, had an interesting result with some peru today. the coffee roasted to the profile i set, all was great, first crack at 9min second at 15. but after cooling i examined the surface and it was still rippled. had good results with almost all other roasts...
    tried it, tasted right but was and am unsure what caused the rippling to remain, to much heat to quickly? not enough? to long roast? any help with developing a constant even surface would b great. h

    I think I know what you mean. This kind of rippling on the surface is something I associate with the bean not quite fully expanding and I notice it in roasts that we pull around or just before second crack. Havent noticed it in any particular beans over others tho.

    Cheers

    Gday Joe... :)

    This guide from Sweet Marias.... http://www.sweetmarias.com/roasting-VisualGuideV2.php is very helpful with regard to understanding the effects of roast progression on the bean appearance. It is only a guide naturally and some bean types will appear slightly different at similar stages of the roast, nonetheless it is still quite useful... 8-)

    yeah after reading that i guess theres more sense just random that the bean had similar crevasses to the beans of pic 6 but was in early stages of 2nd Crack...
    but yes as you say each bean reacts differently! thanks for the ref.
