batch size...

I for one and thrilled to see your batch size come to the market. If I were to ask members here what they wanted in a home roaster they could purchase it would be larger capacity for roasting at home without going to a small commercial roaster that will cost them way too much and take up too much space. While we do not know your price point your batch size is unprecedented for a home roaster. To be able to roast 2 pounds of coffee on your countertop is amazing. My Hot Top will do 9 ounces if I push it. If you look at our builders be it drum, fluid bed or other type of roaster they all build for batch size. Also Jonas, you are going to get asked so I will simply do it, do you have some idea of what you plan to sell her for? Your Bullet... Thank you for taking time to field questions with our membership. ginny Edited by ginny on 03/14/2014 12:16 PM

Newbie Posts: 34 Joined: March 13, 2014	Hi Ginny As you said, 9 ounces is not much, and this was the inspiration for the Bullet. As far as the price goes, I really dont want to say too much at the moment, but it will be more than the Hot-Top, and less than the Cheap 1Kg Chinese roasters. Jonas

Newbie Posts: 34 Joined: March 13, 2014	The minimum batch we have tested is 250g. The temp readings will not be accurate if you go much below this, but you might still be able to program it to less than 250g, even its not something we have had the chance to try yet.

1/2 Pounder Posts: 295 Joined: December 20, 2006	How does a full 1kg batch do at a light roast level? With the efficiency of the roaster and heavy drum do you still have adequate braking to control roast momentum for a properly developed clean and sweet light/city roast. The profiles you show are all well into second crack where you can get away with carrying the momentum through 1st crack. Ed B.

Newbie Posts: 34 Joined: March 13, 2014	Hi Farmroast Great question. The drum is 2mm thick, so its not really heavy compared to many other 1kg roasters. Its heavy compared to other home roasters. :-) First of all, the power response is quick because of the efficiency of the heat system, but we also have a really powerful fan. You can stall the roast by running the fan at full power, so I dont think it would be hard to make a profile as you describe. The reason we show the roasts that go into second crack is because it would be cheating if the roast was ended between FC and SC and we state 12min. If you can send us a profile that you would like to try to "copy", then we would like the challenge. Jonas

1/2 Pounder Posts: 295 Joined: December 20, 2006	Hi Jonas, It's not as easy as just suggesting a profile. The heat transfer dynamics of every roaster is really different. A really experienced roaster of all roast levels and a solid understanding of various roasters has to examine how the beans are reacting during all points along the roast with the various control and specific design dynamics. With this one can really determine the potential of the roaster to not just turn beans brown but can really make for great results in the cup. If you were closer I'd love to test it out for you. Would strongly recommend convincing a top progressive roaster/cupper to do some serious testing for you. This will help determine the spectrum of your potential market. Too many little roasters have been released without this level of testing and early claims brought into reality. It's then often realized that either slight modifications should have been improved before production or that after production user will realize and do needed modifications. For liability issues for both involved it is far better to avoid this before hand than to have a lot of future hacking happening. Those of us who have been around for a while have seen this problem far too often. best, Ed Edited by ginny on 06/02/2015 8:39 AM Ed B.

Newbie Posts: 34 Joined: March 13, 2014	Hi Ed Thanks for the reply. I think I have mentioned this in previous posts, but we are collaborating with two experts- one in Denmark, and now one in Taiwan as well. You are right, the heat transfer dynamics is different in every roaster, but since we are using a solid drum, together with proper agitation, airflow as on the commercial machines, and variable drum speed its not to difficult to emulate the commercial electrics roasters... sort of. The idea behind the Bullet R1 is to take the best and proven- the solid drum, but modernize everything else. Sure we can discuss other ways of roasting, but we wanted something "classic". What we have tasted so far has been really great, but we will do even more cupping in the coming month. I can promise you that we will not release a product that has not been testes and approved by the best of the best in the business. We are also planning a small tour to let the end user try it out and taste for themselves ( Europe, US, and Australia ). If this roaster will not be something truly special ( at least to me ) I wouldn't bother to make it! :-) Where in the world are you? I hope you will have a chance to see it for yourself soon, and would still like to see what kind of profile you are talking about as we have not done many really light roasts yet. Jonas

1/2 Pounder Posts: 295 Joined: December 20, 2006	Scott, With my opportunities to talk with top roasters around the world the last couple years it's been fascinating realizing just how much is happening and changing in roasting. We have seen the upgraditis with home roasters. Many wanting something just a little larger that this roaster could satisfy. We have family, close friends and work that before long catch on to what we are doing and desire our roasts. Lots more interest in nano craft pro roasting within the buy local movement. Other levels of Pro's are thinking more about capable small profile development roasters and not just limited control sample roasters. They have added much more monitoring abilities to their production roasters and are doing more experimenting with ever more challenging profiles and beans. Ed B.

1/2 Pounder Posts: 295 Joined: December 20, 2006	Jonus, I'm in Massachusetts, east coast of USA, Really the specific roaster and it's design and the specific beans used is what determines the profile needed for what basically boils down to as clean and sweet a roast as possible. Light roasting becomes more popular because of the higher quality beans now available to both home roasters and all levels of craft roasters. Light roast bring out more of what's special in these beans. But light roasting is also more challenging and demanding of a capable roaster. We often recommend finding the very best roaster that you can buy a bag of roasted from and will also sell you some green beans of the same lot. Then see how close you can get to there roast in the cup. Even after a few attempts and logging the data and cup results we could then help with some finer adjustments Ed B.

Simply not true. -g I'll rephrase, some great beans are so well grown and processed that are both pretty defect free(important for a light roast) and have some great subtle unique notes that can often only be substantially distinguished at a lighter roast level. This is not to say that these beans don't also present wonderful roasts and spectrum of flavor notes at other roast levels. I've focused on light roasts only because they are generally considered the most challenging and best test of a roasting machines abilities. Ed B.

I can get a great light roast in my Hot Top and Quest. I don't need to have data from experts and the exact temp I will need or should have to get there - it works for me as well as others.

Administrator Posts: 1780 Joined: March 06, 2010	n here lies two different perspectives on homeroasting. Both are relevant. There are some highly technical homeroasting people out there. They are passionate about digging into the details. Many share their research....free of charge. A benefit to all of us. Then there are also now some folks that just want fresh coffee. They had some of mine, now they want their own. They really don't want to think very hard about it. They are the mid and late adopters The more technical folks are generally the "early adopters". They build, tweak and modify. Early adopters are normally not very profitable*** but, they lead the way to the advances that make later products more useful to the larger market. The market desire for a larger capacity roaster is proof that the early adopters are paving the way for a broader market. If I were manufacturing machines, I would be targeting the larger market. They buy more units, and they don't whine as much. For a lot of people, it really doesn't have to be the best cup in the world. It simply has to be the best within a range of convenience. From that perspective, easy controls and 1lb capacity are a winner. Imagine someone having a coffee roaster that was as easy as their super-auto brewer. What a wonderful world it could be. -Cheers -Scott

1/2 Pounder Posts: 295 Joined: December 20, 2006	Early or advanced homeroasters are thinking about the broader casual users. We are not asking for more complicated or expensive units. We are actually interested in making success easier for casual users and all other potential users. It needn't be an either or situation. Same as we are trying to make pro roasting easier for the many without 20 years of sensory experience. Casual users deserve as good an outcome as possible, agreed? Without naming names a couple simple examples, it was found that a slight design change limited tipping scorching on a roaster. Another with chaff singeing issue had possible solutions that would make using safer. Neither of these changes would have effected the price point of these roasters or how complicated it would be to use. The homeroasting market is and always will be rather small. It not the type of appliance that can justify the costs of putting out new and improved models every year or so. Best to work out every little thing that can be thought of before the final design goes into production. That's all I've been trying to imply. Edited by ginny on 06/02/2015 8:38 AM Ed B.

Newbie Posts: 34 Joined: March 13, 2014	Hi Ed I totally agree with you. We would love our product to be something that you yourself would like to use, but also people just starting out roasting, that's why we have the different modes of operation- there will be so much more to talk about when we start optimizing the software. We also try to make the heating and power transfer as consistent as possible to make it easier to repeat a roast. As I said previously- we are not pro roasters, so our collaboration with the pros is vital for our success. If you were in the same neighborhood I would invite you over to try. Jonas
