      I have written a review of sorts:
      Kaffelogic Benchtop Coffee Roaster

      I love coffee, I’m not fanatical about it, but I’m prepared to do more to ensure that I get a good coffee every time I make it than most of my friends and family would be. I even enjoy the small ritual of grinding and tamping and steaming so much that I’m happy to get out of bed in the morning at 6am to go and make coffee.
      Over the years I’ve had lots of different coffee equipment and I’ve tried many things to make a consistently good cuppa. However as I stated I’m not fanatical and I don’t keep experimenting if I’m happy with my current results. Once I got an E61 espresso machine I didn’t need to go further in that direction, I like looking at even nicer machines (especially the lever machines) but I’m not tempted to buy one because I can consistently produce shots that I am happy with using the machine I have.
      One essential ingredient for good coffee is freshly roasted, good quality coffee. This is pretty readily available around Melbourne but I have found the freshness to really affect the resulting drink a lot. If I buy 500g of coffee that was roasted 7 days earlier, it tastes great for the next 7 days and then still pretty good (after adjusting the grind) for another 7 days and after that it’s just ok. When my schedule means that I can use the coffee in less than a fortnight that’s great but sometimes I can’t and stress levels around the house go up if we should (God forbid) run out of coffee.
      For this reason I’ve long wanted to roast my own coffee. However, in the past when I looked into it, it seemed that only the fanatics did that. Most roasters need you to watch them and listen for the first crack then use your stopwatch to get the right level. I read about fires and burnt batches and wasted coffee. I might enjoy sitting outside stirring a batch of coffee beans on a skillet in the evening for fun but I imagine it’s like camping. (Fun for a change when you’re on holiday but tiresome when you have to go to work the next day)
      There’s also the smoke, I don’t have a shed and most roasters have a batch size that produces too much smoke for a regular kitchen.
      The Kaffelogic coffee roaster addresses most of my concerns about roasting your own coffee beans. It is small and it can be used indoors (under a rangehood with the fan going). I mostly use it on our verandah because our rangehood is noisy. More importantly I don’t have to watch it.
      I use the supplied scoop to measure the green beans, (I don’t bother with scales), I put them in the roaster, I turn it on and select the roast level and then I hit go. Ten minutes later I pour out fresh, perfectly roasted coffee. The chimney collects the chaff produced by the roasting coffee and it needs to be emptied every other batch, I just shake it out onto the garden. It takes no longer than knocking the puck out of a portafilter.
      The roaster has the ability to adjust the profile in all manner of fancy ways, it even has a usb slot and you can download free software to create custom profiles. I can’t review those features because I haven’t bothered to use them, I just use the default profile. I only use a narrow range of levels at that. 2.0 is the lowest setting before the roast starts getting too grassy for me and 2.5 is the highest before the coffee starts losing character (it’s still pretty drinkable above 2.5 but it’s not getting better.)
      The beans I’ve been testing with are PNG and Brazil Peaberry both from TalkCoffee where I bought the roaster, these are both excellent beans and taste good from 2.0 to 2.5 but I like the Peaberry best at 2.1 and the PNG best at 2.3. I also use Decaf Wow from CoffeeSnobs (which is as good as decaf gets and better than most caffeinated beans that you get from the supermarket), I like it best at 2.5.
      The batch size of one scoop is about 100g (roasted) this is a small amount that my household uses in a day or two, so I am always drinking very fresh coffee beans, I haven’t let a batch rest for longer than 5 days and that was only because it tasted too green, a few days rest did improve it but I still prefer to roast it and start using it the next day.
      Green coffee stays good for at least 12 months so I can buy a few kilos of green coffee and always have fresh coffee without fear of running out.
      The roaster is pretty expensive, possibly due to a lot of features I don’t use, but it’s nicely presented and won’t look too bad beside your chrome bling machine, if you choose to leave it in the kitchen.
      I will miss looking at the new toys and chatting with Chris at TalkCoffee where I used to buy most of my freshly roasted coffee but I have no regrets about the roaster.


      Details
      The Model:
      Kaffelogic Nano 7
      The Box:
      The roaster package has a large fancy box, inside is the roaster and the chimney. The scoop and a usb memory stick come with individual boxes inside the main box. It’s a lot of packaging but not many items. The scoop is a simple piece of plastic that doesn’t look like much but it’s the perfect shape for its purpose. The usb stick is just a standard memory stick that you could get anywhere.
      Batch Size:
      You might be able to roast smaller batches than one scoop but that’s the biggest batch you can do and it’s already pretty small. If you want to roast a lot of coffee this is not the machine for you. There is no wastage in the batches, every bean that goes in is evenly roasted to the same level.
      Safety:
      The body of the roaster gets too hot to touch during a batch but when the little screen says cool done (10-12 minutes from go), I can remove the chimney and tip out the coffee without getting my hands uncomfortably hot.
      Controls and Display:
      There’s a 2 line display and 5 little push buttons. (Not counting the on/off switch on the side and the USB port on the back). The + and - buttons adjust the roasting level and the > button starts the batch. I haven’t bothered to work out what the other buttons do. Similarly the display shows the time elapsed and temperatures and more but I don’t even look at it. It displays the roasting level of the batch before you start and says ’Cool Done’ when the batch is finished and that’s enough for me.
      Noise:
      The roaster distributes heat through the beans by means of a fan. It is moderately noisy during a batch but still much quieter than my range hood or most coffee grinders.

        Hi coffee enthusiasts we are having a great time on the nano 7 we have used it daily for over a year now and it hasn’t missed a beat. I think it’s a better option than the ikawa as it doesn’t retain heat so if you are doing multiple roasts you have far better consistency. They’re cheaper to buy over here in NZ as well, you can get the gst off and only around $50 to ship.

          Agree with all of the above, I'm enjoying it immensely. I bought mine online in NZ (Ripe in Wellington) and had it sent to a NZ mail forwarder (Private Box) who then sent it on to Brisbane. All up just over $1k AUD. They are around $1600 in Aus.

            Me too. I've had it for a couple of weeks and it is phenomenal. The Behmor I've used for the past 8 years or so is a very blunt instrument in comparison.

              And, quite a bit cheaper too...

                If there is any substance in this, you hit the jackpot as you landed one at way under Australian wholesale price. No need to buy a lotto ticket!

                I know the Kaffelogic guys and they advise that NZ prices have risen and with freight, the Nano will attract the usual import charges on arrival into Australia. They have also stated that there is no warranty for NZ roasters resident in Australia. In addition, NZ retailers are not permitted to sell into Australia.

                Kaffelogic are looking to grow the brand in Australia and as such, you could only assume that numbers and margins in the supply chain will be examined as well.

                It's cool kit and well worth keeping an eye on if you like to roast clean, repeatable and often.

                  I am looking at buying my first roaster after recently starting my coffee journey. I was considering the new Behmor as it seems well reviewed but just wondering why the lack of love with the above comments. Is it the lack of control or the quality of roast produced? Been using a popper and loving the taste of the roast (when I can get all the espresso extraction variables right). Everyone else that has tasted it also love it and are saying it is better than a cafe.

                  Is the Behmor the logical next step up or is it a Gene, Kaffelogic or Hottop? I prefer to buy something right the first time but is it a case of learning to crawl before I walk?

                    The Gene, Kaffelogic and Hottop are all capable of producing excellent roasts.

                    Often, the decision of one over the other, is a matter of personal choices in regard to batch size, roast control and managing chaff and smoke.

                      Hi Thomas

                      I use the K-logic classic profile and I find that anything 3 or higher is too dark for me it’s not that it tastes terrible but I can’t tell the difference between different beans when they are roasted so dark. I find that between 2 and 2.5 works pretty well for all the beans I’ve used. I haven’t tried that many different beans as 2.5 Kg lasts a couple of months and I’ve only had it since Christmas.

                      It’s a bit wasted on me all the configurability of the roaster but I love that I get consistent results with so little effort and I roast a batch nearly every day.

                      My current beans are 50/50 Ethiopian Harar and Indonesian West Java, I haven’t tried different proportions, I roast them both at 2.3 and they make a nice shot of espresso, so I don’t experiment further. As I said in my review the previous beans were good too. I’m sorry I can’t tell you a lot more but I tend to just stop experimenting once I’m happy with it.

                      Cheers

                        Hi Under, who is Thomas? Just trying to follow info on this roaster and not sure who you are replying to?

                        Hi 338 Thomas is me, Quester. I had PM'd 'Under' and he kindly answered, as above, here for the benefit of this thread.
                        I have had the Nano 7 just for a couple of months so have lots to learn. The KaffeLogic community is very good and complements this site.
                        with a maximum capacity of around 120gms, it is practical to limit it to about 100gms to stop the odd bean escaping into the chaff collector/chimney. 15 minutes per cycle - say 11 roasting and 4 cooling - in round figures. about 45 minutes for 300gm less, say average 17% weight loss approx. As Under pointed out. It is the incredible accuracy and repeatability of this machine and you can share it. The beans are cooled by the powerful fan so don't carry on cooking as they appear to with other roasters.....so much - perhaps. Thanks for contributions anyways. T

                        Thanks Quester, always confusing reading the answer when you aren't sure what the question is.

                      100g is 5-6 double shots - it is too small for me. I would consider it if they make 300-400g version.
                      I know I can run multiple batches - that's what I would do with 300-400g model. 100g model would require a lot more batches.

                        I don’t disagree - a roaster with the same capabilities, but a larger batch size would be nice. Of course this would make it double the price and out of reach of most people. I think you’d be surprised by how easy it is to roast 200g in the Kaffelogic. Two 100g batches done back to back would be done in about 20-25min with no set up and minimal clean up. If I want to roast 200g in the Behmor it takes little time to set up, but 12-15min to roast followed by 10-15min of cool down and clean up. Don’t get me wrong I love my Behmor and it’s still half the price, but it doesn’t provide the clean, quick and easy user experience that the Kaffelogic does.

                          I agree with Leroy. The entire workflow from setup, roast, to clean up needs to be considered.

                          The Kaffelogic is an "on-demand" roaster. Think of it as a continuous supply of freshly roasted coffee. The only requirement is to plan ahead so that the beans are rested to your liking.

                          It can sit on your bench so there's no setup time. Roasts are 10 to 12 minutes including cool down. There is minimal smoke so its possible to roast in-doors under the range hood. No need to go out to the shed in the cold of winter.

                          Also, the small batch size allows ample opportunity to experiment and dial-in new beans without much waste.

                            In general terms is air roasted 'rest time' shorter then drum roasted? It is okay to shoot me down with a bean by bean variable type response. it just seems to me the KL resting times maybe shorter.

                              Real ballpark figures here, FNQ, but you plug in a supplied USB stick to record logs, or, if not using the Default and good built in profile, choose another profile and set your preferred Roast Level. The profile/bean/quantity then determine the complete cycle length for that roast. Typically I find the whole process is between 12 & 15 minutes per 100gm with approximately the last 25% of time dedicated to cooling the beans to 30 degrees, quickly. Empty them out, pour in the next lot, as Sam has stated above, Change beans or profiles if you like, and do your next batch.
                              I haven't used a Gene or Behmor so can't speak for them, but my understanding is that this machine cools the smaller quantity of beans down more quickly and provides a very even and consistent roast. I locate mine on a large breadboard, on the induction hob, under the range hood and open windows to help airflow. Hope that helps

                            How do you guys find roasting quality on a kaffelogic vs behmor? Are they similar?

                            Would you say you prefer kaffelogic heavily over the behmor for roasting simplicity and profiling?
