    The Kaffelogic is the best home roaster I’ve used, hands down. It’s automation makes professionally roasted coffee accessible to newbies like me, and its online community and easy-to-read roasting manual accelerates your learning and understanding of coffee roasting.

    It has repeatably made mind-blowing espresso and filter roasts, and can make them as ‘ready to drink’ (between 0 and 3 days for optimum flavor) or ‘rest’ (ready to drink in 3-5 days’ time).

    Ready to Drink is a game changer because when paired with the KL’s automatic roasting it means you can wake up, pour your green beans in, set it to roast while you get breakfast ready, then 10-15 minutes later tip the beans into your hopper and brew some of the finest stuff you’ve ever tasted.
    If you have an eclectic taste like mine, you love to order a range of green beans and try them all. What you need is a small batch roaster like the KL, that gives you profiles off the bat to roast with for each coffee origin. You can then enjoy something different each day of the week, roasted to the best of that bean’s potential for the desired brew method.

    As mentioned, there is a very helpful online community which creates and shares profiles using the Kaffelogic Studio software. You can use the software to create and tinker with profiles, or simply to review your roast logs and diagnose defects and plan their improvements. Everyone is helpful.
    As you start to use the roaster more often, you’ll be tempted to discover more of its functionality. A favourite of mine, which has helped me to learn more about roasting, is the ability to log first crack which then triggers a Roast Development (RD) counter so you can then stop it at the desired RD. I’ve since learned that renowned roaster Scott Rao recommends RD of 20-25%. The Kaffelogic then translates this into its own ‘level’ that means next time, say you can’t monitor the roast but you roasted to level 2.1, you can set it at that, and let it rip. It will automatically start cooling once it again reaches the desired level. Automation plus repeatability.

    Of course, you can tinker with this. But it’s nice to easily be able to apply these rules to home roasting and enjoy the results.

    The Cons? Surprisingly, NOT the price. You do get what you pay for here. It’s more so the lack of an app to see your roast in real time, like an Ikawa. And for some users, you need the full 240v on the power otherwise some profiles might flatline. There are ways to manage around this, but just beware. That’s it. Otherwise the only other dilemma is deciding what you’ll drink next!

    Thanks to Talk Coffee for their prompt delivery and outstanding service, too.

    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.

    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.

    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.

    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.
