    Ill have to give this a try, Ive got some Costa Rica coming. Ive been bringing the heat up slower to FC.
    Note this method may not work with every origin. For example, Brazil, Sumatran,Sulawesi etc.... Beans that needs a good slow ramp up of heat to maximize the body and sweetness. If you do the long preheat method with those, youll actually end up losing lots of flavour.

    But dont just take my word for it, experiment for yourself!

    What temp profile did you use for the roast itself?
    If you meant the Tarrazu Roast, then its as follow,

    Preheat to 250c for 10mins, load bean. Start roast with unrestrained heat (250c), Actual temperature immediately drops to about 200c. got to FC at roughly 10mins, turn down heat to 230c and got first few snaps of SC at about 15mins. Cool immediately.

    I use to do temp profile for the Gene roaster at the beginning, but I found the ambient temperature affect it so much, now I really just roast by sound,smell and feel. Its just a few types of beans I have to watch out for, for example Peaberry where it needs less preheat as a steady ramp up of temp is preferred.

    Genecafe Roaster - Long Preheat, good for Acid

    I have always found the Gene Cafe Roaster good for any Beans that requires a slow roast for Body and Sweetness rather than Acid, so I was never really happy with the Central American Roast until a couple weeks ago.

    What I did was I preheated the roaster to 250c for 10mins, then switched off the power from the main so it doesnt try to cool it down, take out the roasting chamber (use oven mitts as its super HOT) quickly put in the green bean, lock and load and start the roast. The temperature will quickly drop to about 200c due to the introduction of cold green bean, but I managed to get to the First Crack in less than 10mins... something impossible without preheat and got my roast done within 15mins, then emergency eject the beans into custom built cooler and cool it down to room temp in 3mins. The result was spectacular! The Costa Rican Roayl Tarrazu tasted exactly like how Andy described it, like a Green Apple. I am a happy boy!!!
