Nucleus Link Sample Roaster | features, benefits and live roast

[@JonFairhurst]

I’ve got the 110v Nano 7. This looks great for traveling, with the case and dual voltage. That’s not really needed for home users. I like that it calibrates with altitude and density. I live at 2100 feet elevation, and I found that I needed to calibrate the fan speed slightly higher than the factory setting. Regarding batch weight and density, I need to manually adjust things, which is an estimation. But I don’t know that I would just go for their profile recommendations. Your example roast was a bit fast. I’d probably be logging dry, FC, and drop times and adjusting from there anyway. The Nano can be a mixed bag. On one bean, my starter profile was a bad match, and despite adjustments, I had a run of failures. On a different bean and starter profile, the first batch was slightly dark, my adjustment was slightly light. I split the difference and every batch after that was a Goldilocks roast. I gifted it and got huge praise. I’m now of the mind that auto this and auto that might work sometimes, but it’s not plug and play. Learning how to roast well with a variety of beans takes effort and learning. On the other hand, you might find a Goldilocks roast, buy many kilos of that bean, rinse and repeat.

Thank you for your detailed feedback!

Since many of you have been asking, I recorded a video on the differences between the Kaffelogic Nano 7 and the Nucleus Link: kzbin.info/www/bejne/p4G5kH9tgr5ql6M

[@plan9fromsyracuse]

Wow, did they just get in on the kaffelogic indiegogo early then reverse engineer it? It's almost the the same design, right down to the LCD display and 5 buttons, collector chamber. Even the software looks similar. Who would've thought we are watching the coffee version of Ford vs Ferrari?

[@CoffeeRoasting]

It's a close collaboration between Kaffeelogic and Nucleus. I'll talk more about their similarities and differences in another video soon.

i could be doing something wrong however when i use the tube to measure density of beans if i tare out scale with the lid on tube the reading is always too low to register a profile when put into the app.. i have to tare the density tube without the lid to get a reading the app will recognize.

[@CoffeeRoasting]

You need to tare it without the lid. You need to mesure how many grams of coffee are in the tube. That for the tube must be the same with and without the beans.

[@danielcorrea2300]

Do you recommend for home use?

[@CoffeeRoasting]

Yes, it's a perfect machine for home users as well. It's small, simple to use and can easily be stored in the kitchen. Also the amount of smoke is totally okay and can be managed by a conventional kitchen vent.

[@DR19X]

Hi, does this roaster run on dual voltage110 and 220v?

[@CoffeeRoasting]

Not the same machine. You should either buy a 110V or a 220V machine. We've got both in stock.

[@annadelay7847]

How are you doing the "load size" onto the machine? 14:04 on your video.

[@CoffeeRoasting]

After having chosen the profile and before starting the roast, there is an option to adapt the load size with the + and - buttons.

[@maikapsiaozx]

Whats the profile difference in between A to E?

[@CoffeeRoasting]

There is a detailled explanation in the handbook. The biggest difference is the Roast Development Time Ration (time after first crack vs. total time) but they are also slightly different in their curve and bring out some different aspects of the coffee.

[@insankamildjajadikarta5596]

What the difference between this machine and kaffelogic?

[@CoffeeRoasting]

I'll make a video on that.

[@philipsegal8475]

You did not talk about how to set level of roast, dark, medium,light?

[@CoffeeRoasting]

I'll do more videos where I go further into details.

This looks like a pretty uncreative rip of the Kaffelogic. I find it hard to believe they accidentally designed the exact same form factor, controls, and screen. Would love to see some more innovation or variation instead of a copy-paste.

[@cricocoo]

I would not call the Kaffelogic that creative either ... they are both fancy popcorn machines for the coffee professional. The important part is not how they look like but how good the software is they run on, and the data they were/are able to collect. For the home roaster, they do not make sense. It is much more fun to manually interact with your popcorn machine and coffee

[@CoffeeRoasting]

You may have seen that I did a video in the meantime, where I explained about the collaboration of Nucleus and Kaffelogic and about the differences of the machines: kzbin.info/www/bejne/p4G5kH9tgr5ql6M

12 kg, looks heavy

[@CoffeeRoasting]

12kg can easily be carried. Usually you are with a car anyway.
