The Progression from First Crack to Second Crack:
The first series of cracks will last somewhere between 1 and 1.5 minutes depending upon on bean type and
quantity of beans being roasted. Decaffeinated and aged or monsoon coffees will go through these stages and
become darker more quickly than regular coffees. Think of this series of cracks as your alarm bell. At this point
your coffee will be tan in color and, depending upon one’s own tastes, or bean type, can be stopped any time
from this point on. 2
nd
crack is not a requirement for ending your roast.
There is often, but not always, a silent period between first and second crack. During this period, the coffee is
taking on more of its distinct flavors and darker colors. Depending upon one’s own tastes and bean type, the
roasting cycle can be stopped and cooling begins.
If you have chosen to try a darker roast, you will continue beyond this point and hear the cracking sounds start
up again. This is second crack. Again, the sounds will initially be irregular. Now is when most of the greatest
nuances and flavor characteristics emerge. Most excellent single origin coffees and some blends invariably
show their greatest character when sent into the cooling stage at the start of or just prior to the start of second
crack. If you do choose a Full City+, we strongly recommend you reduce the amount of coffee you are roasting
to 336 grams/ 12 ounces for greater control
.
At this time manual cooling can be started by pressing “Cool” if the timer has not run out and activated the
default cooling cycle.
Important Reminders About Roasting:
1. You are in control of the roaster so never leave the roaster unattended when roasting coffee. The
Behmor
2000AB
Plus is NOT a set and walk away device.
2. Never roast past 10 seconds into 2
nd
crack.
3. You can end a roast at any time by pressing the cool button.
4. Allow 1 hour between roasts
5. In Case of a bean ignition, never open the chamber door. The Behmor 2000AB Plus should (but may
not) automatically react to a bean ignition and shut down with an error message. Once the system has
performed a shutdown, unplug the roaster and, if possible, move it outdoors for proper venting. Causes
of such an ignition would likely be traced back to using a high chaff coffee or allowing a roast to go well
past 10 seconds into 2
nd
crack. As instructed earlier, we strongly advise against the use of high chaff
producing coffees or roasting past 10 seconds into 2
nd
crack.

Part 5: Tips
1. Always forward think your roast by 15 seconds. This is the amount of time that is required to start
reversing the trend from roasting to cooling. Whether new to, or experienced with roasting coffee, start
off by roasting at least four (4) 10grams (P1 profile) batches to begin developing an understanding of the
subtle nuances of roasting coffee with the Behmor 2000AB Plus.
2.
Never gauge your degree of roast by the appearance or non-appearance of “oils” . The Behmor,
being a drum roaster (much like professional coffee roasting equipment) does not tend to form visible
“oil” during the roast but rather oil droplets will start to appear in about 24 hours, building up further
after several days of rest. If you see heavy smoke, bluish smoke or are in a heavy rolling 2
nd
crack your
beans are “dark” and in imminent danger of igniting. Press COOL.
