V7.4 Plus OP-L
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) ¼ pound (P1
profile) batches to begin developing an understanding of the subtle nuances of roasting coffee with the Behmor 1600 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.
3. Key Tip – ‘Rosetta Stone’: To better anticipate a roast hitting 2
nd
crack and for additional roast control use the
following time guides.
Adjust times as close to the following using the + or - buttons once you hear the first cracking sound of 1C. This allows you
to more accurately control and understand where you are in a roast, especially in cases where you have a bean type that
migrates from 1C to 2C seamlessly. This also helps to prevent you from over-roasting your beans.
a. ¼ lb - 1:30 minutes
b. ½ lb - 2:10 minutes
c. 1 lb – 3:10 minutes
The times shown are approximately the time it takes from start of the very first snaps of 1
st
crack (1C) to the start of 2
nd
crack (2C) for regular coffee. Decaf and aged coffees, such as Malabar, roast faster and get darker more quickly
4. Roasting times may vary due to voltage, but a good understanding of the A, B, C, D (Program /Times) to Profiles P1,
P2, etc., is as follows:
A to P1
B to P2
C to P3
D to P4 (subtract 30 seconds using)
D to P5 (add 30 seconds using)
5. Associated initial start times of A, B, C, D to weights ¼ , ½ , 1
¼ ½ 1
A 8:30 12:00 18:00
B 9:30 13:00 20:00
C 10:00 14:00 21:30
D 10:30 15:00 23:00
6. In order to prevent possible issues with over-roasting, we have built in maximum roast times associated with each
profile. If you should happen to be roasting at P1, the system is designed to prevent you from allotting more than 20:30
minutes roast time. This is a safety feature. The same feature is true for the other profiles but with longer times.
¼ ½ 1
P1 10 13:30 20:30
P2 10:30 14:30 22:30
P3 11 15:30 23:30
P4 11:30 16:30 24:30
P5 12:30 17:30 25:30
* When using P1 or P2, in certain instances, Program times C and D, may appear not to function. This is intentional. In those
instances C and D’s pre-programmed start times exceed the maximum allowed roast time for that profile.
