We are inviting Mr. Nakaji as a special guest to showcase the excellence of BESCA. You’ll be able to taste Ethiopian coffee from Trans Seagull. This coffee was roasted by Mr. Nakaji using BESCA — and amazingly, it was roasted remotely! A brand-new attempt: operating a roaster in Chiba from Karuizawa, and successfully achieving a perfect roast ✌️
Point 2
All of our staff are professional roasters who use BESCA in their daily work. Roasters from across Japan will share their experiences and insights about BESCA. Since they use it professionally, you can hear genuine feedback you won’t get anywhere else!
Point 3
You’ll also have the chance to taste coffee from each staff member’s own shop. Some roasters have even roasted special batches just for SCAJ visitors!

As SCAJ approaches, we’ve summarized the key features and performance points of BESCA 😊 If you keep these in mind while checking out other companies’ products, the differences will be crystal clear.
Until now, I’ve avoided making strong statements, but I truly believe BESCA products are outstanding.
The more you learn about them, the more you’ll see why I highly recommend them. Of course, there is always room for improvement, but what makes BESCA truly special is the way they are constantly working hard to refine and develop their machines!
A Quick Summary of BESCA’s Features
Here are the highlights of BESCA!!
I’ve put them together (in a simple(?) but detailed way).

1. Pre-mix burner included
Since the pre-mix burner is a very big selling point of BESCA, I’m writing about it a bit persistently!
Its roles:
• By mixing gas and air beforehand, combustion efficiency is high.
• Flame is more stable; combustion temperature is uniform.
• Fine adjustment of heat is easy, so roast profile reproducibility is high.
• Exhaust gas is clean; less odor and soot.
About the metal knit burner
Using metal fibers (in knit form) to form the flame, resulting in surface combustion that emits a soft radiative heat.
A blue flame (short flame) gives a good balance between radiative and convective heat.
Because it’s not direct flame but combined heating (hot air + radiative heat), there is less uneven burning on the bean surface.
Peak flame temperature is relatively lower, so risk of chipping or scorching is reduced.
Compatibility with semi-hot-air roasters
Semi-hot-air type roasters roast using both hot air and drum contact heat.
Metal-knit + pre-mix provides clean and stable hot air temperature, improving control over the roast curve.
There’s less direct flame feel; leaning towards clean cup, making it easier to preserve fruity characters.
Advantages
Clean, low in soot; exhaust & maintenance are easy.
Microscopic heat adjustment possible → high reproducibility of roast profiles.
Flavor comes out bright; acid quality can be cleanly maintained.
Disadvantages
If the burner gets dirty, heat output drops, so regular burner cleaning is needed. → But then again, regular cleaning is needed for all roasters, so it’s hard to call this a big disadvantage.
High initial cost. Even though it’s understood to be high performance, few brands adopt it because of cost.
Compared to companies like Diedrich and newer Joper models (Japanese ones not yet equipped), BESCA has been using this for about 7 years.
Below is a comparison table with other companies (Giesen, Easy Star, etc.) that use atmospheric burners. For reference.
In summary:
The pre-mix burner used by BESCA is…
environmentally friendly, allows fine control, mixes gas and air ahead of combustion so it is very stable and not influenced by outside air.
The burner is like the heart of the roaster. BESCA does not skimp even on invisible internal parts!!
2. Double-Walled Drum
By making the drum wall double layered, the heat from the burner is not directly transmitted to the beans — this avoids surface scorching.
The shape of the fins has been developed carefully to make stirring/mixing of beans efficient.
3. Drum Speed Control Possible
Being able to vary the drum’s RPM at will allows fine control over when conduction heating is used vs when convective heat dominates.
This feature is very important and nowadays practically essential for modern roasters.
4. Direct Motor Drive
The motor drives directly, without belts, chains, or gears.
This avoids unnecessary load on the motor (e.g. switching between exhaust fan operation during roasting and cooling exhaust via lever), thus extending motor lifespan.
Also, people using other roasters are surprised: BESCA machines make almost no operational noise while running.
Truly, you rarely find such a quiet roaster!
5. Stepless Control of Flame Power & Exhaust Fan Speed
On manual machines there are knobs; on automatic ones there are slide bars, allowing very fine adjustment.
Effects from outside air / seasonal changes can also be controlled through these fine adjustments.
6. No Cut Corners Even in the Internal Structure
For example, plumbing that routes the heat from inside the drum up to the cyclone is built inside the body of the roaster, so little chaff or other debris accumulates.
Compared to roasters that have external piping, BESCA’s piping is remarkably clean.
Fewer cleanings are needed, which is very important when using a roaster regularly.
7. PC Connection Standard
Connections to systems like Artisan and Cropster are standard.
Other brands often require expensive modifications to add PC connectivity; with BESCA it comes equipped as standard.
In particular, with Cropster, BESCA is among the four manufacturers whose roasters are fully controllable.
8. Gas Type Changeable Afterwards
Easily switch between propane and city-gas!
If the environment changes, and you need to go from city-gas to propane (or vice versa), most manufacturers require replacing the whole burner, and people from the manufacturer to do it.
BESCA is designed so that you can change gas type easily, without changing the burner.
9. About Delivery Time
Currently, manufacturing takes about 2-3 months, and shipping takes about 1 week (by air freight).
Delivery time has become longer than before, but still I think it’s an astonishingly fast speed!
Shipping by sea could reduce cost somewhat, but I don’t really recommend it. Given war and uncertain canal routes, arrival times are unpredictable, so I recommend air shipping.
10. Finally
Honestly, BESCA is very well made, and I sincerely want many people to use it.
I’m not trying to force it on anyone. Compare it with other roasters.
Even the fine craftsmanship and internal parts (which you can’t see) are very well done.
There are many more small details I couldn’t write here, but I’d love to tell you in detail when you come by SCAJ or visit for a tour!
