Capable of roasting up to 10 ounces of green coffee beans, the Gene Cafe is exceptionally quiet and produces a very consistent roast. This roaster allows extensive control over the roasting beans - the temperature can be instantly changed with the turn of a knob. And the real-time temperature readout means you always know the temperature inside the roasting chamber (although you still must keep in mind that the internal bean temperature will be 50-100F degrees higher after the first crack).

The glass roasting chamber also allows you to see the beans as they roast so you can easily watch the roast progress through the various stages. Control, consistency and quiet operation - you can't go wrong with the Gene Cafe Coffee Roaster!

MoreCoffee Product Review:

I was impressed with the Gene Cafe. The control is key...this roaster provides excellent control over the roasting beans. With the digital readout and knob for changing the temperature, it doesn't get much more straight forward. The Gene Cafe also makes very little noise in comparison to some of the noisier air roasters. With a 10 ounce capacity, you get quite an improvement over some of the other roasters out there - putting the capacity of this roaster right up there with the HotTop at a less painful price. You can also do back-to-back roasts without a problem - and if you use your own cooling device (a colander and fan will suffice just fine), you can roast quite a bit of coffee in a hurry.

Beans that produce a lot of chaff (a fine paper-like skin that comes off the bean during the roast) can clog the chaff "screen". This doesn't seem to create much of a problem, other than a bit of chaff ending up in the final beans (which can be blown out fairly easily).

The roast cycle, even at the max temperature, is fairly long - with a delayed first crack and quite a bit of time in between the first and second cracks. This gives you a bit of time to decide where you want to end the roast - but it does extend the time of your roast, too (it's not nearly as fast as the i-Roast).

One feature I particularly like is the ability to ramp up or reduce the roast temperature at any point throughout the roast. This is a big improvement over the i-Roast in that you don't need to program your roast curves in before you know how the bean will react to the heat. You can apply more heat to power through the second crack, or reduce the roast temperature to prolong it. It's up to you.

Takes a little getting used to
I will probably raise to 5 stars after I get used to using this roaster. Definitely different than my Behmor. Getting used to temperature settings will take a bit of experimentation. Also, the beans seem to continue to roast for a longer period after one goes to cool which tends to go past city or full city where I like my beans.

Buy this roaster!!!
This is my first venture into the world of coffee roasting and it couldn’t be any easier with the gene cafe. Great results even on my first roast! It is as easy or complex as you care to make it. Setup, cleanup, and maintenance is simple. Well worth the money. Highly recommend!

Great Roaster
I would highly recommend this roaster.

The pros:
light enough to move around into storage,
the electric cord is a good length of about 5-6 feet (so I can position it under my hood),
it's quiet,
I can hear 1st and even 2nd crack (though I might have to put my ear closer to the chaff vent)
I can see the beans
I can adjust the time and temperature on the fly
I can roast up to 250 g and end up with a very uniform roast. More could be done, but depending on the bean the results may vary
If you choose to use a makeshift ducting vent attached to the chaff collector, you might not be able to hear 1st/2nd crack. I usually keep it off until I hear 1st crack, then I slip it on as this is when it will really start to get smokey. I can hear 2nd crack pretty easy without having to remove the vent.

The cons:
It does need prewarming for about 5 minutes despite directions
The cool cycle is not great - it takes about 10 minutes to get the beans to about 100-150 (depending on what temp you end your roast at). If i use the cool cycle, my roast ends up a little on the flat end. This could be a problem with me, I am not sure. I would like to hear how the cool cycle fares with other users.

My fixes:
I use a fan to cool the beans. Just as the beans enter the cool cycle, I do an emergency stop, dump the beans, and place them in a colander on a fan. 250 g cools in about 2 minutes. (I do this part outside)

If this were to get stolen, I would buy this again in a heartbeat. It's also about 5 pounds lighter than a hottop, which matters for me.
