|Gene Cafe with big chaff collector|
How does it work?
|Weight of beans before roasting|
|Filling the drum chamber|
The Gene Cafe have a maximum drum capacity of 300 gr. of green beans, which is two and a half scoops (incl. item). There is for safety precautions printed a maximum capacity line on the outer PYREX glass to ensure that you keep this. In case of too many beans in the drum chamber, the consistency of the roast will lack and your cup will suffer of some sourness from the beans that aren't fully roasted. This could also be an experiment because the flavors will vary more. To fill the drum chamber, just pop the lid and fill in your green coffee beans.
The above youtube video is the first produced by Coffee Channel and is therefore this exact roast. The essence in this is simply to insert the drum chamber in the roasting machine and set the preferred roasting time and heat. The Gene Cafe will then roast the beans at the chosen temperature and heat and afterwards start its cooling cycle which last for 10 min.. A thing to keep in mind is that this roaster doesn't start at the correct temperature, but instead builds it up and thereby giving a slow roast. In this roast the roaster reached the set temperature 2 min. before ending the circle.
|Weight after the roast|
The coffee beans have decreased their weight by 29 gr. which is a total loss at 15 percent. This is actually right on the spot for this Full City roast, so I'm pleased with the result. It was the first I have roasted this particularly bean and therefore its very easy to roast.
|The final roasting result|
The Gene Cafe has a lot of great features, for example you can easily set the heat and the time of the roast. This makes it very easy to adjust to and therefore giving great roasts right away, which I really enjoy. Its a perfect roaster for the type of consumer, who never reads the manual and just go along with it, cause its so simple. BUT after you have learned the machine the roasting fun seems lacking, because the roaster just handles almost everything for you. You can't really fool around with it and program some custom roasting profiles, which is a shame. I would like for the future Gene Cafe to include a panel which allows the user to set different roasting profiles and experiment a bit more. The gene cafe also has its own cool down system, which is a nice feature but just a little too slow, because it takes 10 min. for the roaster to cool down the temperature and thereby the beans. Therefore I would like to see a better and more effective cool down system on a future machine. Otherwise its a perfect home roaster and I would recommend this to everybody in a heart beat, so if you are wondering if you should invest in a roaster, than the answer is YES! By the way, you can also save about 25-25% if you home roast, compared to the retailer price.
