    Having great fun playing with the behmor. Bought another 5kg of beans, 5 different regions I can blend and play with. Iv noticed some of my original Perivian SO roasts are getting considerably better after 3 days of resting and hopefully they should continue to improve over the coming days. Lost much of the sourness they originally had.

    I tried mh first blend today. I pre blended 250g of Peru Ceja De Salva and some Indonesian beans 50/50 mix. Ran them on a P2 cycle and cooled just prior to second crack. Looking forward to the result over the coming days.

    Its safe to say im totally hooked on the roasting.

    Hi to All,
    Awaiting the arrival of my new Behmor 1600 Plus 240V with the Heatsnob. It will come with some Peru AAA. I was hoping for some suggestions on my first roast ever!! I would like to start with 100g batch, then work my way up. Your help is very much appreciated.
    Pressing what button when?

    Thank you in advance

    Regards

    Everything you need to know to get started is in this thread so read it a few times. The manual isn't very well written so I suggest you read that a few times as well as parts of it won't make much sense until you've used the machine a few times. Do the 4 x 100g roasts as they suggest, but pay attention and maybe try using the Rosetta Stone during these trial roasts so you actually learn something from them. After that it's just trial and error. There's already plenty of info online so do plenty of Googling and reading. Good luck.

    bumping this thread, as it's been a great resource to me so far in my behmor roasting, and i'd like to contribute.

    finally achieved my first light roast yesterday, and cupped it today without any signs of smoky or ashy notes - but a little cereal-y. i'm currently roasting yirg kochere. 200g, P1 A, 0% power at R1C for 30s, and then cool. my previous roasts have all ended up on the darker side, and i think this is due to me applying too much heat during first crack. i'm thinking of taking the suggestion in the OP, and doubling the drum speed to get a more vigorous first crack.

    Sounds like a washed Yirg? If I was roasting it I would follow a similar process, but it would be more along the lines of:

    250g batch (I have lots of success with this batch size as the Behmor is very particular when it comes to this variable)

    200-P1-start

    Monitor B temp (and Heatsnob if you have one) and make sure the temp starts to climb again around the 7min mark. If it doesn't I would hit P4 at this point.

    About 1min before first crack hit P5 (unless having already hit P4 earlier is giving it enough heat and a great enough ROR)

    30-60secs before first crack hit D

    Hit P3 and C at first crack.

    Hit D again to slow drum speed about 30secs into rolling first crack

    Adjust heat up or down if necessary, bit usually I find it's not needed.

    Hit cool whenever you're ready once first crack has finished. Could be anywhere from 5-90secs after the end of first crack depending on what you're going for.

    This would be what I'd try first and I'd make adjustments based on the results.

    thanks for that! i don't have any temperature probes or software, and i haven't been monitoring ET so far.

    i've been away, so got a chance to fire up the behmor yesterday. i'm trying to change just one variable per roast at the moment, so i went with:

    200g yirg kochere (washed, as you guessed)
    P1 A Start 0:00 (i'm using a stopwatch)
    P5 and D at 8:30
    (very first crack at 8:50)
    (rolling first crack at 9:15)
    P1 and D at 9:30
    Cool at 10:00

    drinking a v60 of that right now. getting a lot more acidity and less muddled fruit sweetness, but now there's a more roasty and bitter element, and this is at a 17.6% extraction. i'm guessing that i improved the development and the evenness through the increased drum speed causing a more even first crack, but also increased the end roast degree. come to think of it, i think i'll try this through the flair espresso next...it might be a nice third-wave light espresso roast. :P

    now, you say to make sure that the temperature starts climbing again around the 7min mark? what happens to cause a temperature shift at this time? with P1, the temperature should be at maximum.

    so had another couple of cracks at the yirg, dropping earlier and earlier until it just tasted cerealy, and finally decided to go back to the original recommendations (p1 through first crack, then back up to p3 for 30s then drop), where i was getting both fruit and roasty ash. This time, I took the plunge and opened the door partially when I hit cool. Messy, but it’s made the world of difference. Gone are the ashy notes from the v60 - it’s tasting a lot closer to the filter roasts I’ve bought. Now instead of just dropping earlier, I can focus on development.
