  • Advice on roasting Jamaican Blue in Behmor

    Anyone got any tips on doing this before I accidently burn $96/kg of beans to a crisp?

    I would suggest that you be very familiar with the Behmor before placing JBM init. I am assuming that you have at least 20 to 30 roasts under your belt? I am nudging over 60 roasts and if it were me I would be watching it like a hawk!

    Good luck but I would be doing a small roast of say 250g and 1IbP4C setting. Will be interested to see how this pans out

      Re: Advice on roasting Jamaican Blue in Behmor

      I have been roasting JBM for 2 years in the Behmor. I have had best results with lower size roasts and roasting at P3 (1 pound setting). I now roast 240g batches, but did 285g last year.

      Here are my recent notes:

      "First outliers of first crack at 4:00
      Rolling first crack at 3:40

      Set timer for 10 seconds - when timer goes off, open door fully
      Set timer for 30 seconds - when timer goes off, close door

      Set timer for :25 with door closed, then open door for 15 seconds
      Then do it again ...
      Set timer for :25 with door closed, then open door for 15 seconds

      Then press cool to start cycle
      After 1 minute, press OFF, remove beans to external bean cooler
      Then restart Behmor by pressing Cool

      Wait 3 DAYS for roasted beans to mature"

        Nice detailed reply rgrosz78, the only gotcha is that you are using a 115v roaster and the 240v one does work a little differently. Could be a good guideline though.

        The JBM is expensive but once you get over that they are very easy to roast and you should get a good result first time.

        If it was me...
        200g - 1/2 pound / P2 / Start

        Keep a close eye on it towards the end of the roast and hit cool 45-60 seconds odd after 1st crack, it should coast into the edge of second crack

        A 200g roast is "only" $20 of beans, not too spooky a risk if you look at that way.

          Right, Andy! My 115v Behmor roasts very slowly - over 200 roasts and 2 years old.

            I stuffed up most of my roasts of it. Only had 1kg so could only do 4 x 250gm roasts (this is in a baby roaster, not Behmor though). My best roast was the lightest batch, so my advice would be to not take it too dark, stopping before or just on first snaps of 2nd crack.

              Re: Advice on roasting Jamaican Blue in Behmor

              I couldnt find much advice on a behmor roast for this coffee when i did it a few weeks ago, the one thing i could find suggested a p5 1 pound D with 350g batch, the method also suggested winding the time down to 20mins before starting the roast then adding the time back as needed. (unsure what purpose this served)

              Roasted without a hitch, pulled at first signs of 2nd crack.
              Tastes phenomenal, one of the best Ive had in quite a while.
              Right up there with Bani Ismail which is my all time favourite.

              Will try Andys P2 method next time for sure.

                When I started roasting JBM in the Behmor, I asked several experienced roasters. They all said this is coffee needs a slower ramp to first crack than most other coffees.

                In particular, those roasters said NOT to use P1 - since that has the fastest ramp to 1st crack of the various Behmor programs. There is very little difference between P1 and P2 - they both ramp very quickly to 1st crack.

                So I am still recommending P3 for this bean. I also tried P4 and P5, but those were a bit TOO slow.
