    Brrr! Cold weather roasting

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I did a roast of Decaf this morning in Perth.

    As usual I roasted outside under the patio, which has yet to cause me a problem until this morning.

    It was bitterly cold today, with lots of rain and cold wind.... that being said, we were roasting in a reasonably wind proofed area.

    I roasted for 22 mins, and the cracks were very difficult to hear.... The beans look the right colour, and smoked quite a bit.... I think theyll be alright... I guess Ill find out tomorrow.

    Has anyone else had touble with cold/wet weather effecting their roast quality?

    Re: Brrr! Cold weather roasting

    Hi Lovebite,

    Im also from Perth and I roasted yesterday afternoon when it was quite cold, about 12 degrees. I roasted some Ethiopian Harar and Hawaiian Kona. I found that the cool weather also extended my roast times, but in a beneficial sense. The Harar took just under 10 minutes to roast to the very first snaps of 2nd crack. This was using a B&D popper with chimney, roasting 120G of beans. I was agreeably surprised by the more appealing aromas coming from the double espresso that I usually have. It seemed less coarse than the previous batch which roasted to the same spot in just under 8 minutes when the weather was significantly warmer.

    The Kona took about 12 minutes to get to the same stage and has also turned out nicely.

    Interesting to see the very long roasting time for your decaf. My experience with decaf is that 1st and 2nd cracks have not been as noticeable as with full strength beans and I recall during some roasts hardly hearing any first crack, just a snap or two with 2nd crack being similar.

    I guess the cooler weather would be a good thing for us Perth popper roasters (PPRs!) as longer roast times are supposed to mean a better resultant flavour profile according to the experts.

    I havent done enough cold weather roasting to be really sure on this one

    Cheers,

    Louis

    Mmm,

    Yes, up here in Woodvale, Perth. Bloody cold alright.

    Black and Decker is defnitely the right way to do it.

    i havent used a chimney on mine and it has been recommended to me but Im quite happy with my snappy short roasts and I have been very pleased with most of my roasts.

    I did do the Bolivian Carnavi and started a thread on Cupping but didnt like this or the Brazilian too acid/sour.

    I am a fan of the decaf and it comes out perfect every time on the roaster although I havent timed it. I would guess six minutes. I take it to the start of the second crack and so far each roast has been very even and consistent. To my surprise I even like it as a straight espresso. The colour at this point is darker than any of my other roasts.

    I also love the indonesian Java and the PNG Purosa in the starter pack. Both are very tastey coffees that may benefit from blending but are bloody nice on their own.

    I am thinking about the Hearthware I-Roast at the moment. I could be tempted to buy one but my $20 popper has done me three years and hundreds of roasts and is still going strong.

    Hhhmmmm....I wonder how long a popper roast would take up here in the winter time. 2 hours? Maybe 3? :o

    Re: Brrr! Cold weather roasting

    Over here in Perth we dont have anywhere near the cold weather that you have in Melbourne and over in Javaphile territory. A significant problem is how to lengyhen our roast times during the warmer weather. I know that the airpoppers can be modified by fiddling with the electrics as has been pointed out. But I remember reading that you can lengthen the roast time by using an extension lead. I will give it a go but does anyone know if this makes a difference.

    I am definitely not a sparky!

    Re: Brrr! Cold weather roasting

    Yes you can indeed lengthen your roast by using an extension cord due to the voltage drop it will cause. The exact degree of change will be determined by the length and gauge of the cord.

    WARNING!!!!!! Monitor the cord carefully and do this at your own risk as the cord will warm up and even get hot enough to ignite if its long enough or a small enough gauge!! Also take into consideration the age, size, and condition of the wiring in your house. If its old undersized wire, personally Id put a chimney on the popper before using an extension cord. :)

    Its because of the cold winters up here (down to -35C or so) that Ive not gone the BBQ roaster route. :-X

    Re: Brrr! Cold weather roasting

    How cold was it in Perth today?!!..
    My roasts seemed to last for ages (almost long enough to tidy the garage!)
    Im not a sparky either so cant really help but just wanted to say hi to my fellow PPRs
    Seems like there is enough of us to organise some sort of get together one day in the future? (I vote Grants place as he has the Silvia/Rocky combo :))
    Cheers,
    Matt

    Matt:

    Down to 11.5 degrees today. Coldest Perth day in 10 years and coldest June day in 39 years or something.

    I will organise a visit to my place for some serious tasting shootouts.

    I will start a thread when I organise a time. A Saturday afternoon would probably be good. Im in Woodvale south of Joondalup and about 20k or so north of the city.

    If you have any suggestions let me know.

    I was thinking of just bringing along your favourite bean. We could also organise a tasting of just one bean that perhaps most of us have so that we can have a roasting shootout using the same green beans.

    I am open to suggestions.

    Grant (love to see yall Watt)

    Re: Brrr! Cold weather roasting

    Sounds pretty competitive....

    I dont mind the idea of a Perth get together though....

    I live in Joondalup..... but have car will travel.

    Id happy have you all to my humble abode, but Id get booed out of the CS community with my super auto (I like it so leave me alone).

    Im going to try the Decaf tomorrow... 48 hours rest is more than enough in my opinion. Ill be interested to see how it measures up to my other decaf roast given the longer roast times.

    My decaf generall takes around 17-18 minutes, with the trust XU1 heat gun, and a SS saucepan. this batch was 22 (or something...what did I say yesterday?)... fingers crossed, I could be in for a big surprise.

    Hey James,

    Dont think of CSers as being competitive. Id like to think of yours truly as not being so. What counts most in my books, and Im sure I would speak for most of the others and that is PASSION for what you are doing.

    The reason INMH that people like our mate Java phile for example are fun to read is not so much that they have a swag of gear but for the sheer joy that exudes from between the lines that they have written.

    Cheers,

    Louis (PPR)

    Re: Brrr! Cold weather roasting

    Sounds great guys!
    I think its a great idea to get together and compare our roasts.
    And maybe swap some beans.. Beans? Who said beans?..
    Think Id better come clean though... I live in the Gee (Willagee).
    Thats right... Im a southy.
    If we have it down here youll have to car-pool (so you only have the one car stolen ;))
