Dan's Direct-Flame Roaster

Oh, there's a little code I built in to the numbering. They were random, except that the smaller number of the two everyone received was the flame roasted sample, in your case, #14.

I suppose that could be true about the aroma. Next time I'll isolate them better.


Dan, according to the code my #7 was the flame roast. It also had significant oil on the surface of the beans, unlike the non flame roast (mine was #12) . Do you think this was due to the roast method or do you think it was because it was actually roasted darker? If I were to do a visual comparison of each I would say that the flame roast #7 was roasted to Vienna and the #12 to full city.

What are your thoughts on this?

The oilyness surprised me. I haven't seen that on other beans I've flame roasted. The two beans were roasted to exactly the same temperature, just a few cracks into 2nd. When I dumped the beans there were exactly the same color, too, at Full City. Strange.

Do you know if other samplers noticed the oilyness or was it just mine? Just curious.

Yeh, it was across the board. It wasn't evident in my samples, but then I kept them frozen. I think it was just this bean!

Dan,

Did you record the temperature throughout both roasts? I'm curious about the temperature ramp and the impact from direct-to-bean radiant heat. If the end temperature of both was the same, could it be that the flame roasted beans had more heat exposure early in the roast?

Back to the aroma, how distinct was the aroma difference to you? I wonder if it was more distinct before the shipping.

No, no data logging. And, I doubt if it would be possible in the flame roaster anyway. The problem is that it would be near impossible to duplicate the same profile on different roasters, and if you did, you might not like the results. I'm afraid this is just going to be an apples and oranges kind of thing.

It was very distinct to me, and I've noticed this has applied to other beans I've roasted, too. It seems to be a flame roaster quality.


One idea I had for a future test is to not try and do side-by-side comparisons, but just roast a bean everyone has some experience with and you can judge for yourselves. I'm thinking of using the standard Costa Rica Tarrazu Hacienda la Minita.

Dan, I agree with the apples and oranges analogy. I think your roaster is a perfect fit for a farmers market outdoor type of environment. The smell of the beans roasting plus the visuals of the beans tumbling through the flames would be an outstanding presentation.

Question: Have you thought of a way to adapt to an indoor environment? Maybe a powerful ventilation hood over the machine? Seems to me that if that could be done it would also be a big draw for a coffee shop.

With a hand crank and a propane tank, it would be an awesome camping accessory. Just set it up next to your cook stove.

I hadn't thought about those two ideas. It is fun to hear the beans tumbling and watch the huge flame at work. It would be a big draw at a farmer's market.

Ditto with a smaller camper's model. Although, I'd go for the model with a 12VDC gearmotor powered by the camper! Like mine, both could be fueled by a 20 pound LP tank.

Indoors is a possibility, you'd need a vent hood, but the cfm needed wouldn't be very high.

Considering I started with two $10 stainless steel mixing bowls you can't go wrong. Good ideas!

When i go camping its usually in forested areas. So... To paraphrase a familiar icon: Remember. Only YOU can prevent coffee roaster related wildfires. Imagine all the explaining one would have to do. And would have to leave everything behind. Except the most precious items. Like the coffee roaster! For me at least, its much safer to bring along an adequate supply of ROASTED beans. And less cumbersome. I would also strongly advise against using any campsite water for brewing. Bring adequate non chlorinated water.
Bad coffee prevails when good coffee roasters stand by and do nothing.

Oh - these were Brazilian? That might explain why they were so smooth as espresso.

I apologize for not taking part in scoring, I thought it'd be a lot easier to score than it was! The beans tasted almost the same to me, although they looked a little different and certainly smelled different. The smell made it through not only the ziplock, but also into the mailing box, and now a couple weeks out, it STILL smells that way. I really like the scent, it reminds me of steak.

Thanks, Jed!
