    First Roast

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All,

    Just thought Id say gday. Just took the plunge yesterday. Bought my popper last weekend (Magic Popper), and the beans finally arrived on Friday (Kenyan AA). Have read a lot about poppers and their temperature problems, but being new, I thought Id start with a completely unmodified popper and see how it turned out.

    Everyone here was pretty much spot on, the popper roasts very quickly. I dont have a thermometer yet and am too inexperienced to pick the first and second crack. I did hear the first crack about 4 minutes in. I left it another couple of minutes, but didnt hear anything else. The beans were starting to get very dark in colour so I thought Id take it off the heat and transfer to the collander. They looked pretty good. What I considered to be a nice medium roast. I left them in an open paper bag overnight and cupped this morning.

    Coffee was very undeveloped. It had very mild acidity but had not developed any of the body Id come to expect from well roasted beans. Im guessing a) I should have let it roast longer, and b) I should actually modify the popper to allow more air in to slow it down a bit.

    People have suggested a chimney before. I thought it was just to channel the smoke out, but its really to stop all the beans overflowing from the chamber. They get MUCH bigger during the roasting and start to come out the chute during the process.

    So - for next time:
    * Add a chute extension (a-la chopped tin can)
    * Remove the half sealed air intake at the bottom of the popper
    * Elevate the popper so its off the bench a little (to improve airflow)
    * Wait for the second crack!

    Cheers,

    Pete

    Welcome Pete
    I havent used a popper in ages and from memory in really needed to listen carefully for 2nd crack.

    I wouldnt leave the beans in an open paper bag, as soon as they are cooled place them into a one way valve sealable coffee bag to ensure they stay fresh. The valve will let the CO2 gasses out but will not let air into the beans.

    I generally leave my roasts 3 - 4 days before trying, unless of course i have miss judged the qty i am using and nearly run out. I did a roast about an hour ago and only have about 150gm of roasted left from my last batch so i think i will be using a fresh roast tomorrow, if i do another couple of roasts then i can stock up and let them sit a few days be for. One way to see how the flavour develops is to sample a shot at say day 1, 3,5,7,9 etc. and you will see a change over time.

    Chimney is a great idea, i also used to put a piece of wood over the top approx 50% to keep heat into the unit and that would ensure 2nd crack at about 8 mins or so.

    Keep on roasting

    Re: First Roast

    Thanks for your reply Mal. Some good ideas in there - like trying the coffee daily for a few days. Ive read a lot of different opinions about when coffee is supposed to peak after a roast, ranging from 4 hours to 5 days. Ill decide based on what I think taste bests and leave it at that :)

    I also dont have any valve bags, but I believe CoffeeParts sell them so Ill pick up a few.

    I must say its great not to have to work out all of this stuff my myself. Doing stuff like this would have been ten times harder without sites like CS.

    Re: First Roast

    A bean will peak when it is the best for you. I find most beans change their flavour day to day and like Yirg it starts off floral and light with caramel (to me) and 5 to 7 days after roast the cocoa comes through and it fills the mouth, but I roast a local bean I get up here and it is great 2 days after roast.

    So as they say try some each day with the different beans and you will find a wide variety in flavour.

    A temperature measuring device is fine but with a popper sight, sound and smell are more important (to me). I find when the bean is the colour you are aiming for then you pull it and see (Black/Grey is not a good colour :( ). If it didnt work out next roast vary the colour. It is a never ending learning curve. There is another curve around the corner from the one you are on. ;) With practice you will hear the different cracks but when you start out hearing the second crack can be illusive. It is usually accompanied by more smoke but in a popper this can be very little due to the small weight of beans you are roasting.

    Gday grumpygeek,

    Welcome to CoffeeSnobs mate.....

    Re: the 1-Way Valve Bags, Im pretty sure that Andy has them available again from the BeanBay (Buy Green button over on the top L/H corner of the page) at quite comparable pricing. Either source is good though as youll receive excellent service from CoffeeParts too.... :)

    Cheers,
    Mal.

    Good idea Mal. Got to pick up my membership card and a starter pack while I was at it.
