    My First Gene Roast

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I just purchased a second-hand Gene Cafe for an absolutely great price (thanks again, Luca!), put a new cog in (thanks for the tips from Chris at Talk Coffee and Ronald from Avacuppa who is the nicest and most helpful man!) and away I went...

    What an absolute beauty and 100% easier than wok roasting - I feel guilty for saying it, because I do love wok roasting, but its starting to feel like a bit of chore, especially now that its getting hotter.

    Pictures below of my first roast, using 300g of my Herbie in celebration (the last of my first bag *:( )

    Its probably a bit darker than I would have liked it, but I now know what 245oC / 16 minutes looks like and can adjust a bit accordingly next time. *How nice and even are they, in comparison to wok roasting, though!!!

    Cooled down via the Gene to 100oC then pulled and cooled the rest of the way in my colanders. Once again, an experiment and next time Ill do the emergency stop and see what the difference in taste is like.

    A huge stack of chaff tipped on to the lawn afterwards, but the Herbie is a huge chaff producer, Ive found.

    Yee-hah, this is fun! *:D

    Cheers
    Di

    Re: My First Gene Roast

    Hiya Hoyks,

    That sounds a bit hot for my money.

    My (almost) standard these days is to set it to 230C and 20 minutes.
    This usually gets me to 1st crack about 12 minutes in, when I reduce the set temperature to 220 over a minute or so.
    2nd crack usually starts about 18 minutes in and I am pulling most beans either just before or just after that time for a roast level of CS 9 to CS 10.

    All this of course can vary with the bean.

    Very chaffy beans usually mean a roast quantity of 250 gm rather than 300, and Monsoon Malabar is measured by volume not weight.

    BTW the Emergency Stop is just that, and can be hard on the equipment.

    I know its a bit slow but I just cool in the machine.

    Greg

    Re: My First Gene Roast

    Thanks Greg - just did a second batch, this time the Sulawesi Tana Taraja Kolosi and, after seeing some threads in a slightly older Gene thread, rang this one at 230oC for about 18 minutes, which seemed to be just on second crack. This is usually when I pull it on the wok (ie; just on 2nd crack) because I prefer my roast at CS8 - CS9.

    Worked much better at 230oC, I have to say - beans arent anywhere near as dark as they were the first time around...different bean, though, I suppose.

    Still did the cool down to 100oC and then pulled and hand cooled again.

    Do you let yours cool all the way down to 60oC, Greg, or pull at 100oC also? Whilst this is still letting cool for the most part, I just found that pulling it off then and doing it manually seemed to take it down to room temperature a lot quicker (says me, oh one with a HUGE amount of experience...not!!!) and I figured this mustnt do the machine any harm, otherwise it wouldnt have it built in.

    Cheers
    Di

    Re: My First Gene Roast

    I tried a number of versions--cool to 60, cool to 100, Emergency Stop, and couldnt tell the difference in taste. Now that was before the Macap (I had a Rocky then) so the info is a bit out of date.

    I suspect the dump at 100 is OK. I did read that the manufacturer or distributor (cant remember exactly) said to use the Emergency Stop for emergencies only as the machine was not designed to use it as a regular feature.

    I do appreciate the ease of cooling to 60 in the machine. Everything is cool enough to handle without gloves or extra implements so I just dump the beans in a freezer bag, put all into a zip-lock bag, and try and restrain myself for at least a couple of days.

    Sometimes I actually manage.

    Greg

    BTW--you need to update your sig. lines! ;D

    Thanks MP - no, thank goodness! 8-)

    Well, tasted the Herbazu today and its delicious! Has a slightly different tang when done in the Gene, but that could be down to the fact that its nice and evenly roasted, rather than mottled from the wok.

    I thought I was down to my last 2.5kg bag of Herbie, but pleasingly found a site sponsor that has a stash of it to buy - not as cheap and only in 1kg lots, but I love this bean so much, Im willing to spend the extra to get some stocks! So, away I go to buy up big on the secret stash! ;)

    I might have to buy the large chaff collector from him also, though, to allow for all the chaff this bean puts out!

    :)
