Order now and we willl ship on or about 7/29. We are one of the largest sellers of Behmor roasters and, in addition to the many that we have sold, we also use several units extensively for roasting in our offices. As of last November there have beenimprovements to both the chaff tray and a simplification of the roasting grid itself. There are no longer two variations of the roasting grid. What was formerly the small grid is now supplied with the roaster and the former grid with slightly larger spacing has been discontinued. From this point forward there will be one grid size only.

As of November 2009 Behmors are shipping with a redesigned Low Profile Chaff Tray. The new chaff tray significantly improves bean visibility, enhances airflow for improved cooling, as well as collects chaff better than its predecessor. It represents Behmor's commitment to improve the roasting experience and results for users of our mutual home roasting customers.

Newly designed Behmor low profile chaff tray (left) provides unobstructed view of roasting grid as compared to original.

The tray has a series of vanes or louvers that open when in the "in use" position, meaning when inside the roaster. During roasting, the chaff that comes off the roasting coffee, is blown over and behind the louvers, trapping it. By doing so, the chance of chaff ignition is all but eliminated while airflow, for the roast itself, is improved. Air passes through the vanes but chaff is left behind. A clever solution and a real enhancement. One of the original criticisms of the Behmor was the difficulty in seeing beans within the roasting chamber as they were partially blocked by the old style chaff tray. A workaround was developed where a piece of the mesh was cutout to allow better vision. Now, with the new low profile chaff tray, that workaround is obsolete. The new chaff tray is only half the height as its predecessor (see above), ending beneath the window in the door. The user now has an unobstructed view of the coffee roasting within!

Behmor 1600 - In Stock and Shipping.

The Behmor Home Roaster is available and shipping. We have a terrific relationship with Joe Behm, the inventor and developer of this roaster, who had been working on it for seven years prior to its introduction. The roaster, prior to its official release, took the Best New Product Award at the 2006 Specialty Coffee Association show in Long Beach, a real coup. The Behmor 1600 was introduced to the public in 2007 and we have been offering the roaster since the first day. Today, very many Behmors are in use and there is a legion of satisfied customer who have become come to enjoy the benefits of home roasting the easy, smokeless way.

The Behmor 1600 roasts 1/4, 1/2 or 1 pound of coffee. It has a choice of five profile programs. You cannot save program changes but some modifications can be made to roasts during a roast cycle to alter results. A terrific feature is the Behmor’s smoke suppression system which is very effective at nearly eliminating roasting smoke and much of the associated aroma. This roaster, as the instructions will tell you, is not for doing dark roasts. The maximum roast darkness is 10 seconds beyond the second crack, which would be approximately a lightly spotted roast, a little beyond Full City, or what you might describe as a ‘light Viennese’. If you wish to roast coffee darker than this you should look at other choices in home roasters. But, if your needs are in the realm of lighter roasts, which are best for coffee’s flavor nuances, the Behmor is a real contender.

The Behmor 1600 offers a lot of surprises and in many ways it is a wolf in sheep’s clothing. Upon opening the shipping box the first impression was that the box itself was substantial. When we took the roaster out of the inner product packaging a few things stood out. Firstly, and everyone will say this, the roaster looks like a toaster oven or perhaps a microwave. I have to admit it’s nicely made and it’s obvious from the outset that a lot of detail and thought has gone into its finishes. The exterior, pull down door has brushed stainless facing out, with a knife shaped ‘window’ a couple of inches tall and nearly the full width of the door. To the right of the door is the control panel and display.

Behmor Construction Details

Open the front door and the first thing that greets you is perforated stainless steel. Upon unpacking the roaster and reading the directions fully, you will learn that this is the chaff collector and it is fabricated of stainless throughout. It has a pivoting grab handle attached to its exterior. On its interior is a shiny stainless ‘dustpan’ floor, which will later be used to catch any chaff that did not get caught in the device. A 2-inch paintbrush, provided, is the ‘broom’. This combination, a little humorous at first, is like many aspects of the Behmor 1600 that you will later come to appreciate. It works.

After removing the chaff collector you will see the cylindrical stainless cage in which coffee actually roasts. When removed, the cage or drum opens on one end and has a clamp to keep it closed.

Small/Large Roasting Cylinder Update

Originally, Behmors were packed with one cylinder and after some time users wanted one with smaller spacing so small or irregular shaped beans would not fall through the grid. Hence, the so-called small grid cylinder was developed. There was a small difference in the openings between the standard and small grids. For some months we at Roastmasters.com offered Behmors with a free small grid as part of our deal. Now, the former small grid has become the standard grid, and the former standard has been retired. The world of Behmor grids is now unified. The reality is, you can roast any coffee in the grid that now comes as standard.

A. Smoke suppression exhaust system - B. Behmor roasting drum

The drum, of course, turns during roasting. It can only attach to the roaster housing and its motor one way. One side of the drum has a square peg that fits into a square hole; the other side is rounded and slips into a receiving collar once the square end is in place. Putting the drum into place is easy but in our test model we sometimes found it a bit difficult removing the drum after a roast. You are to lift up on the left side collared end and, moving the drum to the left, it should withdraw from the square hole. However, this sometimes takes more effort and we think this could stand some improvement. It is not a big detraction, just a detail that should work a little more smoothly.

With the drum out the interior is clean and surrounded by stainless surfaces. At the rear of the roaster are its heating elements, two 525-watt glass-heating elements for a total of 1050 watts, more than other home roasters. This is one reason the Behmor is capable of roasting up to a pound. At the top of the interior is a heated exhaust, which is responsible for removing smoke and some roasting odor. The interior is lit and the light can be turned on after the start of a roast with a button on the control panel; the light goes out after the cooling cycle has ended unless you want to turn it off.

Drum fits into square hole on right and into hook left.

Roasting with the Behmor 1600

This roaster was designed to appeal to a broad range of consumers, meaning that it had to be simple enough to be a home appliance for anyone interested in home roasting without their full immersion in coffee knowledge and roasting technique; but, it also needed to have some of the bells, whistles and controls for the experienced or tech-savvy enthusiast - a tall order and likely an impossible one. What the Behmor lacks for the latter group is readout of bean temperature during roasting, which is standard fare on the Hottop and Gene Café, albeit their accuracy is questionable. There is no thermocouple probe and it seems, due to the design of the rotating drum and how it is attaches to its drive, like it would not be possible to customize the roaster with one, which would also void the warranty. Instead, Behmor bases all roast levels on audible signals given by the coffee itself.

Being a very quiet roaster it is easy to hear coffee go through first crack. Behm has no doubt done laborious measurements to determine about how long it takes for coffee to go from first to second crack under various conditions, such as bean type, weight of coffee being roasted and selected profile. The roaster’s interior 15 watt light provides enough visibility to see bean development; with the advent of the new, low profile chaff tray, you now have an unobstructed view, a real improvement over the taller, original tray. You will get the hang of roasting on the Behmor quickly. You will also find that the profiles built in to the Behmor are very close to what you will likely seek in finished roasts and highly repeatable. This roaster’s ability to repeat results is one of its strengths.

Profiles - As previously mentioned there are five pre-set roasting profiles. Joe Behm, inventor of the Behmor 1600, is not a coffee roaster himself by trade. But, he had valuable input and advice from some experienced industry insiders in developing these profiles. The instructions provided suggest which profile to use for a particular type of bean which they classify as: hard, soft or island. Further, there are specific instructions about roasting ¼, ½, or 1 pound of coffee for each of the profiles. Weight of the coffee being roasted increases roast time, with full pounds reaching more than twenty minutes. This may be of concern to some, but coffee can be roasted for extended times as long as it is not baking or causing beans to chip.

Keypad - The control panel keypad is broken into sections for:

• Roast Weight - ¼, ½, or 1 pound
• Programs - which are initial start times associated with each roast weight
• Time increment - which are really time adjustments. Pressing the + button increases roast time in 15 second increments up to the maximum allowed for each profile and weight combination; the - button decreases roast time in 10 second increments.
• Profiles - variable methods to achieve different taste elements from any given coffee.
• Other buttons - Start, Off, Light and Cool are self-explanatory. Cool begins the cooling cycle immediately.

To do a roast choose a profile and select the appropriate weight of coffee to be roasted (¼, ½, or 1 pound). Once those decisions have been made you would press a series of buttons to start a roast. For example, if you wanted to roast a half pound of hard bean Guatemala at Profile 2, you would press these buttons: 1/2, P2, B, Start. The first button selects the weight, the second the profile, the third, B, sets a time adjustment, in this case 13 minutes, and finally, you press the Start button to begin the roast.

Shown below are the initial start times associated with each weight and program buttons. These can be further adjusted with the plus and minus time increment buttons up to the maximum allowed for each profile and weight combination.

Important: We observed no hot spots, tipping or chipping of the beans during any roast cycles. Beans roasted uniformly. The drum’s design, which has several paddles and vee shapes, provides for ample mixing and movement during roasting. Also of significance, coffee is not roasting in a smoky environment so the roasted beans have a cleaner, brighter taste. Many commercial roasters cannot lay claim to this, not to mention home roasters.

Profiles Detailed

• P1 - Basically ramps right on up to 100% power and keeps that level for 100% of the roast time, producing the quickest roast. Notation: 100/100.
• P2 - Like P1 ramps at 100% for the first 60% of the roasting time, then drops to 70% power for the next 30% of time. Full power for remainder of roast. Notation: 100/60, 70/30, 100/10.
• P3 - A more gradual ramp-up. During the first 20% of time roasts at 70% power; 80% power during next 35% of time; full power during remainder of roast. Notation: 70/20, 80/35, 100/45.
• P4 - A variation on P3. During the first 30% of time roasts at 70% power; 85% power during next 30% of time; full power during remainder of roast. Notation: 70/30, 85/30, 100/40.
• P5 - The longest roast with the slowest, most gradual ramp-up. Roast time is broken into thirds with 70%, 80% and 95% power supplied in each segment respectively. Notation: 70/33, 80/33, 95/34.

Behmor shows P1 and P2 as roasts for Hard Bean coffees; P3 for Soft Bean/low grown coffees; P4 for soft or espresso blends; and, P5 for Island coffees such as those from Hawaii, Jamaica, etc roasted to City/City+. Our own assessment and preference differs slightly for a number of coffees we have roasted. We find ourselves gravitating to P3 for many coffees. This profile provides brightness plus body. The P5 profile is a sharp contrast to the others in that it produces roasts that are definitely skewed toward acidity; many of the mid tones and body are missing. Nonetheless, it is informative to see the effects on the final output.

While the roasting profiles cannot be altered or reprogrammed, it is possible to add or subtract time to roasts once they have started and effectively tweak them in this fashion. This roaster is unique in that you can continue to add increments up to the maximum allowed for each profile and weight combination (see chart below), though be cautioned, once past second crack you will begin to be inundated with smoke and this roaster has not been designed to produce dark roasts. The Hottop by contrast, allows the user to add 5 thirty second Plus Times in total to the preset roast time.

Maximum Roast Times - The roaster will not let you roast longer than the times shown below for each weight and profile as indicated.

Conclusion

The Behmor 1600 has proven to be very popular. The bottom line is that it roasts coffee very well and does so with a minimum of noise and smoke, making it well suited to home use. The price point puts it in reach of most consumers, filling a gap between the smaller roasters that sell for less than $200 and the larger Hottop and Genecafe roasters that sell for hundreds more. Also, the flexibility to roast batches up to a full pound yet as small as a quarter pound is terrific. Profiles are effective. The appearance of the roaster, though not 'roaster-like' will feel at home in kitchens or other areas of the home.
