    Unhappy What am I doing wrong?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hey guys!

    Just got started on my Behmor, and am very fresh to roasting but very keen
    I've been roasting the India Elephant Hills AA

    Post-roast, my beans still seem to have a strip of greenish colour through the centre. This is the same whether I do a lighter or darker roast

    What am I doing wrong?
    (P.s. tried to upload photo but wouldn't let me)

    Any help would be greatly appreciated!

    Welcome. Pretty hard to help if you don't describe your roasting method (weight of beans green, which profile settings or manual settings did you use, when did you hit first crack, how long afterwards did you stop the roast)?

    Hey guys!

    I'm using around 100g of green beans, preheating for 90sec, using the auto P1 profile, First Crack happened after 7mins - I stopped it about a minute later
    Then did the same, but stopped it just as Second Crack started

    Are you talking about the line on the outside of the bean or are you cutting it and referring to what’s inside?

    Can be seen on the outside - but also when I cut in

    Can you take some photos of the beans? Although you might need to post 5 times before you can add them here…
    Sounds like they're under-roasted - and 100g is a pretty small batch.
    Doesn't Andy suggest 400g & P2? If so, P2 would make for a pretty quick roast for 100g, and potentially under-roasted inside… although I'm not a Behmor roaster I'm afraid – so I'll leave the clarification to the pros!

    A p1 100gr load of elephants hills will run from fc,rfc,2nd crack,rolling second crack straight after each other in my experience.

    in my 7 roast and week and a half experience in roasting I have found the yummiest cup of eh so far is a p3 setting with no preheat

    How do the beans taste?

    From my own experience and some assistance from Andy I’ve found this will get pretty consistent results.

    Use 200g or 400g batches. 200g best while practicing.
    No preheat.
    Select P2 and B
    At FC (after several cracks) hit C and P3 for 50% power

    You can let it run the full time to get a decent roast. Alternatively hit the + once for slightly darker or stop it 20sec early for a bit lighter.

    Ambient temp will have an impact though so pay attention. Also take notes while experimenting. repeat what works best.

    I've been using a Pop Corn pump for many years. I have 2 types. Circular air motion and vertical air motion. They both do a fantastic job and can be purchased for approximately $5 at thrift stores. The time to 1st crack is approximately 3-4 minutes. 2nd crack approximately 7-8 minutes. I discard the top part of the pump and insert a makeshift cloths dryer metal pipe for the expansion. I use a "long" wooden dowel with a small tasting spoon attached at one end for viewing samples. The other end is used to stir the beans if required. I've found that periodic stirring helps with the process.

    Any chance of a link to a photo?

    On the issue of the vertical air motion poppers, Kenneth Davids - in his book "Home Coffee Roasting", cautions against use of this type of popper because of the propensity for chaff to "settle into the base of the popper, collect around the heating elements, and eventually cause the device to ignite". He recommends only the circular air motion popper which is the more familiar one in Australia.

    Hi

    I've been roasting with the Behmor 1600 for six years and what I have noticed is that the machine has too many settings for what is a simple process of applying sufficient heat to deliver a high quality roasted bean

    Also the thermostat on the Behmor is highly sensitive to variations in external temperatures and will, on a hot day (over 30c) frequently cut-out before the roast has been done adequately.

    So what I now do is measure out around 10 oz of green coffee beans (that lasts us about a week) hit the 1 lb button and hit start : that will give 18 minutes roasting time and I find that gives a good dark roast which is to our taste. I don't worry about first and second cracks, just the appearance and colour of the roast.

    To overcome the erratic thermostat I usually roast first thing in the morning when the air temperature is stable and I stay with the roaster checking periodically. On a wet morning when the humidity is higher I usually add an extra minute or two (+ button) and the same on a cooler morning.

    I don't use any other settings and consider that Behmor could do themselves a favour with just a simple on/off roaster and leave it to the consumer to visually judge thw type of roast they want.

    All the Best

    Wantok Hi, ... sounds like your onto a winner , bring one onto market;. should be easy competition against the Behmor. Production will be far cheaper with only on/off switch and perhaps a built in roast colour chart.

    Hmmmm. I'm not sure that Behmor are going after the 'same profile for every bean, just cook 'em to the same colour' market. Toaster ovens are much cheaper, and subject to more competition.

    What am I doing wrong?

    Behmor Coffee Roaster
    There’s already plenty of on/off style roasters as well for people who want a simpler experience. A few examples include the Gene Cafe (not quite on/off, but certainly more basic than the Behmor), the iCoffee, the SR500 etc. Also the 220v version of the Behmor doesn’t suffer from the same issues mentioned above by WANTOK.
