Nucleus Link or Kaffelogic Nano 7 | Which is the best sample roaster for you?

[@plan9fromsyracuse]

Kaffelogic owner here--thanks for the side by side comparison. Boost kit is already ordered. 200g is a nice level to roast at home and will hold you over for 1-3 days. Can't go higher than 120 with kaffelogic out of the box, but looks like you can do that with Nucleus. Kaffelogic has RTD ready to drink setting (meant to consume coffee from roast to 3 days) and REST (meant to consume coffee after 3 days from roast). It's all interesting and fascinating. Thanks for the video!

[@CoffeeRoasting]

The Nucleus Link roasts 50 to 100g. The "BOOST function" ist, that you can put in the amount of beans and the machine adapts the roast accordingly. Since different from the Kaffelogic, it's really made for samples, the capacity is limited to 100g.

I think that compare point is 'prepared profile'and 'construct yourself'. Already used link 1 week, and I nought nano7e and pelicase. In my opinion, the reult of thease two machine, same. Different of price is prepared profiles. So gorgeous casual roasters. And most attractive thing is Second derivative graph. I have ROEST roaster too, But roest web app does not show 2dn derivative graph. Anyway thanks for your video footaeges.

[@CoffeeRoasting]

Thanks a lot for your feedback. You are totally right. The two machines are the same in hardware and you have the possibility to do the exactly same with both machines. The big difference is, that the LINK comes with meanwhile more than 700 roasting profiles. Therefore you will have a perfect roast without having to understand roasting. On the other hand, it's so granular, that those taste differences are only to be tasted by people with high sensory skills. The machine is being used successfully for competitons where those small differences matter. In my experience, the profiles you get for the Kaffelogic Nano by the Kaffelogic team as well as by the community are already on a superb level that is higher than for any other roaster out there.

[@bolerkai]

This is an outstanding review of these two products!👍

[@CoffeeRoasting]

Thanks a lot!

[@lintanghutama]

Thank you for the technical insight İngo. Wonderful, concise, and informative video as always from you. İ have several question: 1. Can we connect Link Roaster to artisan or strictly Link Studio? 2. What is the optimal capacity for The Link? 75-80% capacity? 3. How many roast batches can we do with the Link? it is a different engine to Aillio.. But from the Bullet experience. İ am limited to 10-12 batch daily. thank you once again. Lintang

[@CoffeeRoasting]

Thanks for your feedback, Lintang 1. Strictly Link Studio 2. 50 - 100g. The machine is powerful enough for all roasting profiles with 100g 3. No limits as to my knowledge and experience. When I do quality control days, I roast our full assortment of 19 coffees in a row and never experiences any sign of limitations Kind regards Ingo

[@johndoeh781]

Thank you so much for this video. It was really informative and helped me a lot with my purchase decision :)

[@CoffeeRoasting]

Thanks. Happy to hear.

[@commentator2.0]

Which one did you buy?

[@cricocoo]

Thanks for sharing the back story! It does explain the copy-paste feel now, without patent infringements :) Given that extra info, I really don't see any use for the Link for the home roaster: paying +800 euro more for the same machine and then having to find space on your attic for that giant safe box? Does not make sense to me, but maybe I am missing something :D

[@CoffeeRoasting]

Fully depending on your needs. As said, I clearly see the Nucleus Link as a sample roaster for professionals in coffee production, trading and roasting. The Kaffelogic is very popular with home roasters.

[@user-jc1yx9of9p]

Good video! Can you also program a slow roast on the Link, for example a 20 minute roast?

[@CoffeeRoasting]

You can change the roasting profiles on the Link and adapt them to your liking.

[@zeropuckprep]

Cool post. Thanks for the info

[@the_original_mathwiz]

As I understand, the Nucleus Link REQUIRES, after a certain number of roasts, that the owner sends their unit to a maintenance facility to have the unit looked over and refurbished if necessary. Can you give us a ballpark number for what this service costs?

[@nickr9784]

Any chance you will ever make a video for making a basic profile? There isn’t much out there to get started

[@CoffeeRoasting]

Can you tell me a bit more what would help you? Do you mean, how to approach a new profile, or how to technically do it in the Studio software?

[@justinpalentchar6687]

Thsis looks really cool. Just out of curiosity, whats your relationship to kaffelogic and nucleus? Also how would you compare it to the new ikawa coming out. And you saidd in the last video they wanted to make it affordable accessible to many people, how much is the nucleus? I wouldn't call the ikawa affordable... but for what it is its not necessarily over priced.

[@CoffeeRoasting]

The Nucleus Link costs around €2,000. In fact, there are many well-known coffee competitors, roasters and coffee producers who have switched from much more expensive machines to the Nucleus Link. They particularly like the consistency and precision of the machine, as well as it's ease of use and robustness. Kaffelogic and Nucleus work closely together and we like both machines. As you can see in the video, they have a lot in common, but they also have strengths in different areas.

[@LivingTheLifeRetired]

HI Ingo, thanks for your input on the KL forum. You were talking about Link that when you mark first crack the profile will then adapt to that, does it permanently change the profile going forward or just adjust the remainder of the profile for the current batch? Can you just mark first crack in the log but not change the profile? I think just marking is better because as you mention, you can then go to the app and find a profile where the first crack is more aligned to what you had with your particular bean.

[@CoffeeRoasting]

The profile remains unchanged in any case. Not to confuse anyone: Nucleus Link: when marking First Crack, it changes the current roast (unless the FC is as expected). You cannot just mark it with the LINK Kaffelogic Nano: when marking First Crack, the roast will not be affected but FC is being marked in the log.

[@LivingTheLifeRetired]

@@CoffeeRoasting I see. Thank you. In a way then the Link has the advantage that if FC is earlier than expected you can still obtain the desired development time whereas the KL it is possible that the bean will be overdeveloped if FC happens earlier than expected. I was also told that in the settings of the Link if you mark FC you have the option to modify just the current roast or change the FC permanently for that profile.

[@HichamHabbaz]

Do you recommend one of them for those who want to start learning and professionalizing roasting from scratch, and what about the Kaleido roasting machine m1/m2 for the same goal?

[@CoffeeRoasting]

You have to understand that the biggest difference in coffee roasting comes from the choice of beans as well as the final roast colour of the beans. Both you can perfectly learn with those machines. You can also dive deeper into roasting profiles, like time, speed, portion of different roasting stages,... So you can use them well for learning. If you want to learn roasting in order to later work on a drum roaster, I would though recommend using a small drum roaster like the Hottops, Aillio Bullet,... since there you've got the same logic and dynamics as with a larger production roaster (mix of convective and conductive heat transfer, heat source and air flow separately maybe even drum speed, software,...

[@user-gu7iq5mj2q]

hello. I am planning to purchase the link from Asia. It's hard to tell the exact difference because I'm using a translator. The hardware part is the same, but the software part is a little different. Can you explain it briefly? They also say that roasting is possible for practical brewing purposes, so I'm curious what you think about the taste.

[@CoffeeRoasting]

The hardware is the same, the differences are in the software and even more so in the amount and quality of roasting profiles: - Kaffelogic: about 12 roasting profiles / Nucleus Link: more than 400 roasting profiles. They are very granularly developed and of an extremely high quality. They take into consideration the density and processing of the beans. - Kaffelogic: you will need to chose or develop the roasting profiles according to your experiences and sensory / Nucleus Link: the machine comes with a tool to measure density as well as with an app that supports you to find the right roasting profile - Calibration: the Nucleus Link can be super easily calibrated on your altitude. This is particularly important, if you use the machine at different locations and need consistent results / the Kaffelogic can be calibrated as well, but it's not that simple as with the Link. But well enough if you are using it at the same location - Capacity: the Nucleus Link can roast any capacity between 50g and 100g / the Kaffelogic is made for capacity of 90g to 120g but there is an optional BOOST kit that allows for 50g to 200g with the Kaffelogic - Travel: the Nucleus Link comes with a shock absorbant case to travel with the machine / the Kaffelogic comes in a sustainable cardboard box. You can take it safely in a car but if your really need to travel with it, you are better off with the Nucleus Link I hope, this helps a bit

[@looyi8195]

Hi Ingo, thank you very much for your informative video. Please allow me to confirm, the Nucleus Studio software allows user to manually adjust/design a custom roast profile, like what the Nano E studio software does?

[@CoffeeRoasting]

Thanks for your feedback. Yes, you can design and adjust roasting profiles in Nucleus studio as well.

[@andreavoit]

I take advantage of the question to add myself. Is it possible to see the progress of the roasting by connecting the computer with the kaffelogic as well?

[@nickr9784]

Can Link profiles be uploaded to Nano?

[@CoffeeRoasting]

Smart question 🙂 No, they cannot. But in the KZbin Channel of Nucleus Coffee Tools Training you find a lot of information on the profiles so that you can get some inspiration and ideas on how they have been developed.

[@RayCanuck61]

So the difference is the software…. Can the Nano 7 be upgraded with the Link software?

[@CoffeeRoasting]

No, it cannot. It's two different firmwares.

[@floid33556]

Sounds like same hardware , different software, which is more important.

[@CoffeeRoasting]

You are right, it's the same hardware and you can do the same with both machines. The big difference is, that the LINK comes with more than 700 roasting profiles that will allow you to roast competition grade coffee withough having to understand roasting at all. The Nano comes with 12 profiles but in the community you can already also find a lot of additional profiles. So for most of the people and even more so if you like to get an understanding on roasting profiles, the Nano is good enough. But the Link just takes a lot of work from your shoulders if you don't want to invest time in finding a perfect roasting profile.

[@1Larriva]

So let’s see you roast some coffee

[@CoffeeRoasting]

In this video, I did a roast with the machine: kzbin.info/www/bejne/eXWufaptoc16nZI

[@joedrinkscoffee]

I have the Nano. Let’s say I know the density of the bean- is there a way I can log first crack and use this information to adjust the profile accordingly, as the Link is doing? I.e a guide somewhere that would tell me how to manually do what the Link software is doing automatically ?

[@CoffeeRoasting]

No, you would need to manually adapt the profile for the next roasts if you want to change it.
