  1. atitacoffee.com is a new entrant I can recommend. Last season the guy was selling his father's Yirgacheffe naturals. The greens didn't look much but my golly what a taste in the cup. He is now sourcing other beans of Ethiopian origin..
  2. If DavecUK is still chugging on testing this roaster there has been a development.... As well as the the Classic profile loaded on the machine and a few other contributed profiles from enthusiasts Kaffelogic have released twelve official profiles for use with the machine. The company's approach is to choose a profile based on bean density - the analogue, of course, being the bean's grown altitude. https://kaffelogic.com/community/viewtopic.php?f=3&t=201 refers.
  3. Jump at the chance! Although I can't see Jacinda Ardern opening NZ borders to Brits anytime soon. Why would they? No new cases of Corvid-19 in three weeks and us in the UK about to start a second wave. Then a third.. Certification is a red herring: it works fine under Au/NZ certificates. It is 240v and works fine. And you just know the BB price isn't going to be light; they have to pay DavecUK his cut.
  4. You may ask and I respond willingly. My roaster arrived after being thrown about by the couriers. I was warned that the 'reward' models for early backers were packed with 'green', as in environmental and limited, packaging and would likely not perform well for international delivery. So I arranged for it to be delivered to a family member in NZ with the request to her to re-pack before posting. She misunderstood and it got sent on to me as delivered to her. On the way the motor anti-vibration mounts became detached and at first switch on I was met with a rattle and a graunch as the air impeller ground away at its chamber floor. So I needed to disassemble and refit. Unknown to me then, the impeller, a close tolerance item, had been subjected to wear. Much later discussion with Chris Hilder - the designer at Kaffelogic, after not being able to get the required airflow, resulted in a new impeller being sent out free of charge together with other parts to aid proper re-assembly plus parts I have yet to need. There is an art to taking the thing apart and refitting but I would suggest anyone reasonably thoughtful. dextrous and competent at handling a screw driver could cope. I understand there are now instructions on the Kaffelogic website.
  5. Put the machine on its back. When disassembling be careful to keep the black top and the roast chamber together; they are supposed to become an interference fit at first use. And to keep the top and roast chamber in place whilst reassembling I used a large rubber band (of the type the postman delivers). The photo says it all!
  6. OK Chaps! let me make a short commentary on a couple of points I noticed in DavecUK's video review - which is, I understand, work in progress. 1. Kitchen extraction fan; I have an Elica extraction hood. I have no door to my kitchen and on level 2, out of 3 levels, my fan extracts everything outside. I think DavecUK needs to put the cooker-hood extractor on a higher setting. 2. Using the Classic roast program is an excellent place to start. The Classic profile is designed to give around 20 -25% Development Time Ratio using a roast level of 3.3. If you, as DavecUK did, reduce the roast level to 2.3 you are also reducing the Development Time Ratio. Scott Rao suggests 15 - 25% development seem to give the best roasts. By simply reducing roast level as much as DavecUK did you move away from the sweet spot the profile was designed for. If you need lighter roasts, and I do, then you choose another profile which is designed to finish at a lower level. 3. Roasting without the feedback of a USB record of the roast profile is madness - why would you? I think DavecUK's roasts are ending at too high a temperature 225C, if I recall at supposed level 2.3. That seems a bit off to me I would have expected a finish temperature to be lower at around 222C. Maybe DavecUK could post a log and check with Chris Hilder on the Kaffelogic Forum. 4. The Kaffelogic is built like a tank and achieved full electrical safety certification in NZ/Australia; they use 240V as standard. We fudged when joining the EU and our voltages are a nominal 230v. My house mains ranges between 233 and 240V depending on time of day. Other parts of Europe standardized on 220V. EU certification says a device is safe to work on the nominal 230V which really covers the range 220 - 240 in Europe. The device is safe to import.
  7. @DavecUK If you all recall I posted here last year about my initial thoughts on the Kaffleogic Nano 7. I was heavily jumped on for supposedly promoting something dishonestly. I was accused of having a pecuniary interest in the product. I didn't then and don't now. But the natural assumption was 'I was up to no good'. The Kaffelogic Marketing Director was shot to pieces when he chimed in. Some were upset he never used his job title when introducing himself. But he is a Kiwi; the last thing Kiwis do, unlike us Brits, is to puff themselves. He's gone and likely won't come back. So with this forum, ("some say it is the friendliest place on the Internet"), being, in my experience, very suspicious of newcomers - hostile - even, why would I need to bring more ire upon myself by pushing a review? Any way it is Gene, Gene, Gene - in the cold - in the shed - all the way isn't it? Why should I seek to battle closed minds. I daily continue to benefit from my Kaffelogic ownership but why should I tell you that? For is is Gene, Gene, Gene - in the cold - in the shed - all the way isn't it? And besides you really need to roast at least a Kilogram each time don't you? It must be unmanly for a real bloke to fiddle around with grams. But when I try to express a view, my use of language appears to upset snowflakes. In a past comment the words "fat blokes in their shed" must have really got to someone and caused them to run to a moderator. Or they just wanted a reason to make a fuss. @mctrials23 axe to grind. Yes, I probably have. I try to confront patronizing attitudes and misogyny wherever it intersects my sphere. Is that why you feel the need to keep jumping on my comments?
  8. I was not knocking you or your review. Do not put me in with that mob on this board. But you made a 30 minute video; 30 minutes. There was loads of time to explore other features you and I know about. But we got a second rather dreary repetition of a roast, one decimal-point of a level beneath the first. You could have edited out the wait for the second roast and just shown the beans, leaving more time to delve into other features. It was a wasted opportunity. For me, your pace in all your reviews is too slow and your style a touch too pedantic. However, I imagine others might love it. Please don't take offence as none is intended.
  9. No, Sweetie not all at. I think you over-egg your cake. A review is an exposition of a product's features and together with thoughts on those features provided by the reviewer. Whether DavecUK will bring more to his final review is a matter for conjecture, but at this moment his exposition meets the linguistic criteria to be a review. Now I do try hard not to be a pedant but ever since I been on this board I seem to have had blokes trying to put words in my mouth; please don't. And why did you think it important enough to make a fuss about it the first place?
  10. Err? That 30 minute video, I thought? Two roasts, if I recall.
  11. Not concerned, more surprised. I'd always thought your reviews were very comprehensive; I now see you can miss things.
  12. For those worried by support and longevity I can personally confirm both are superb. I have a pre-production model and received free parts, damaged as a result of very careless handling during shipping. I have had my Nano 7 for nearly a year and have completed 254 roasts without problem. DavecUK's review is far from complete; many control features are missed. Logging and tweaking the roast profile are noticeably absent, as is mention of other profiles suited to particular roast styles and/or beans. Finally, to all the vituperative on this forum who assumed my earlier testimony to the Kaffelogic Nano 7 was marketing hype - do have a nice day now.

    PTFE Spray

    Yours, maybe; mine did and it was a regular cleaning point. PTFE is polytetrafloroethylene. It is regarded as inert and is used as a non-stick coating for cooking pans among many other uses. The solvent carrier would be expected to flash-off and leave only PTFE residue. But the thread on the burr follower is miles away from the grind action; I really can't see much chance contamination getting into your cup.

    PTFE Spray

    The problem I had was with coffee grains getting in the threads and making adjustment harder than it should have been. I know that lip salve is sticky. And I can imagine ground coffee would cluster to it. I continue to have surprisingly smooth adjustment since my PTFE spray was applied. However, I should add that I have also done the Nitto Denko tape fix on the circumference of the upper burr carrier - maybe that is stopping ground coffee getting to the threads - who knows. But it is all working very well together now.
