    Colombian *roast pictures

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Fresh off the barbecue roaster, 200 grams of this months coffeeclub Colombian Supremos. I suspect todays strong norherly wind in Melbourne had a cooling effect on the barbecue, because roasting temperatures were several minutes longer than last Saturdays for same beans. This lot took 21 minutes -- about the longest Ive ever done. Normally I can expect 200 grams to be done in about 15 minutes. I find that with most beans weve tried, 2.30 past the very, very, very first crack is the time to stop to get a nice medium-dark brown roast. I have only the middle burner on (high). Oven thermometer fairly near the drum shows 160 degrees C, the one on the lid, on the left side near top, showed 220 degrees C -- and thats about 10 degrees below usual in this weather (25 degrees outside temeprature, with gusty northerly).

    Thanks, Andy. The rotisserie drum roaster (ye olde Milo tin with 600 drilled holes and 3 stirring vanes!) produces very even roasts at some 40 RPM.

    I quickly empty the hot beans into a colander. Then, holding that colander about 450 mm high, slowly tip them into another colander. As the beans fall, a small electric fan held midway between the two colanders blows the lightweight chaff away. The tippng from one colander to the other is repeated a few times until the beans are cool to touch, and theres no chaff left.

    Well we can see your cooling technique works a treat for cleaning the roast too... well done.

    It is ingenuity like yours that is streching the boundries and dispelling the myths of "home roasting".

    I like your work!
