Behmor

The Behmor is probably the best value bench top roaster on the market.  Behm Inc. is very focused on providing an affordable roaster, and on continuing to enhance the functionality of the machine.  All upgrades can be retrofitted to previous models.

We import the Behmor Plus, which  you can purchase here Buy Behmor 1600 Plus.  You will also find how to videos here.

The Behmor controls and roasting profiles are summarised here: Behmor_Info_Sheet.pdf

Behmor - Automatic Mode

You may want to start working with the P1 programme (full heat for the entire roast) while getting used to the machine.  You should be able to hear first and second crack, and it would be good to get used to switching the machine into cooling if you need to (i.e. if you've reached or are about to reach your desired roast level before the programme has completed).

We generally put the machine into cooling either just as or just after second crack begins (depending on the bean) to give a medium roast.  The beans will continue to roast using the ambient heat during the cooling cycle (hence you will now need to get used to anticipating when your beans are "nearly" roasted).

Other roasting profiles drop and raise the heat at various points during the roast - which you will be able to see in the manual.  These changes in temperature are based on the overall calculation time of the roast and what percentage of that roast time you are through the roast.

Before the Behmor plus was released (giving the roaster manual control over the heat), we would roast using the P2 programme in our goal to extend the gap between 1st and 2nd crack - thereby enhancing the flavour and allowing more caramelisation of the sugars in the beans.  It also makes it easier to differentiate between these two critical phases in the roast.

Using 400g P2 B, you will have set up a 20 minute roast time for 350-375g of beans (the weight depending on which bean we are roasting).  The power drop will occur 12 minutes into the roast (machine reads 8 minutes remaining).  Then with two minutes remaining the power goes back up to 100%.  Note that at At 6m30s to go, the panel will start flashing (see Safety Feature below).  Press Start to continue the roast.

After a few roasts with each bean, you can adjust the overall roast time so that first crack (7-6 minutes remaining) happens after the drop and second crack (3-2 minutes remaining) occurs before the increase.

If you are wanting a medium roast, you will need to start the cooling cycle just as second crack starts or even just before – so the roast coasts into second crack as it is cooling.  You should be able to leave it going to get a darker roast (10 seconds, 20 seconds max).

Manual Mode If your panel has buttons with both blue and red surrounding them - this indicates those buttons have a dual purpose AND that you can switch your roaster to Manual Mode.  If you do not have this capability on your Behmor, you can purchase an upgrade panel.

Begin your roast (selecting the weight desired) then press Start.  Once the roast has begun, you can press P1, 2, 3, 4 or 5 to go into Manual mode.  Press 1 at any time to go back to Automatic mode.

• To change the drum speed - press D.  This can have a similar effect to increasing or decreasing the air flow to the beans.
• To change the temperature - press P1-P5 (P1 being 0% - no heat, P2, 25%, P3 50%, P4 75% and P5 100% heat).  This is kind of opposite to Automatic Mode where P1 is 100% all the time, and later programmes varying the heat.
• Press C when you hit 1st crack if you'd like to use the built in countdown - the "ideal" time until 2nd crack based on the weight you have used.  It doesn't change anything about the roast (you need to do that using the heat and drum speed) - but rather gives you a guideline to work to.  Once you get to the end of this countdown, the roaster will automatically go into cooling unless you extend the time to get a darker roast.

Our go to approach for 400g of washed coffee is to start using 400g P1, using the time increment to set the roast time to 20 mins (we only extend the time to make it easier to track the roast).  From this point we can switch to manual mode at any time by pressing P5 (100% heat).

At 6m30s to go, the panel will start flashing (see Safety Feature below).  Press Start to continue the roast.

When the beans hit first crack we use "C" to start the countdown and "P4" to set the temperature to 75%.  When the beans are in rolling 1st crack, we set the temperature to 25% ("P2") to slow things down.

At the moment, we allow the countdown to send the roaster into cooling, finding that we don't need the beans to go quite into 2nd crack for our personal roast preference.

You might want to raise the temperature, and extend the time as the countdown completes, depending on your roast level preference.

Safety Feature

If you have grams on your front panel, rather than pounds, you will also have the safety feature.  At 75% of the way through the roast, the timer will start flashing.  If you do not press Start at this point, you roaster will get an err7 and go straight into cooling.

This ensures that the roast is being monitored when you hit the potential danger period.  Monitoring your roaster obviously helps to avoid "bean ignition".

What's Coming ...

The most common question our customers ask us is "how do we roast this bean"?  Behmor are solving that problem for us.  The next new model will allow you to load your favourite roasts up onto the internet where others can download the roast and drive their roasters from their smart phones.  Of course you will still need to monitor the roast, but you will be able to copy anything we do, and anything our other customers willing to share do, directly into your roaster. It just keeps getting better ....  This is still some time away though (could be years) and while this approach may give you a head start on certain beans, in the long run you will still likely end up tweaking to your own personal preferences.

You can still purchase the current model Behmor with the reassurance that you will be able to upgrade it once this feature becomes available.
