The Hottop Espresso Roaster has been round for a number of years now and has confirmed to be a dependable espresso roaster, and the assist from Michael at Hottop USA has been wonderful; I’ve firsthand expertise, in addition to anecdotal third celebration accounts. They’ve continued to make small, incremental enhancements to the unique base mannequin, offering straightforward do-it-yourself upgrades alongside the way in which. In truth, even the oldest authentic mannequin (KN-8828) could be upgraded to the latest, most costly Scorching high roaster (KN-8828P), fully by the end-user, and in a matter of some minutes.
Perhaps you presently have a KN-8828P Hottop Roaster and wish to get extra out of it. Perhaps you’re considering of upgrading from certainly one of your easier fashions just like the KN8828, KN-8828D, or KN-8828B to the extra superior KN-8828P digital mannequin. Perhaps you’re questioning if you happen to ought to even purchase one, particularly contemplating the hefty price ticket nearing $1000. Hopefully, I can level out not simply fundamental utilization, applications, and upkeep however another finer particulars which may allow you to determine whether or not the KN8828P Scorching High Espresso Roaster is for you.
Fundamental Utilization
The KN-8828P can be utilized out of the field with the “AUTO” program, which is helpful if you wish to get began immediately. Whereas this would possibly work for some, the actual espresso geek will wish to arrange their very own customized applications. We’ll contact on that later.
To get began, you’ll be able to merely energy it on and choose the Computerized program with a few button presses, and the machine will start a Heat-Up cycle, the place the roaster will heat itself as much as the mandatory temperature of about 175 levels Fahrenheit. This ensures that your roast at all times begins on the similar temperature, and ensures repeatable roasts. As soon as prepared, it’ll beep at you, together with a graphic on the LCD, principally asking you to dump your beans in. The really useful inexperienced espresso load is 250 grams (about 9 ounces). I’ve discovered this to be quantity, and by not straying up or down from it, I’ve had good outcomes.
After dumping the beans into the unit via the highest chamber, you’ll hear the beans being agitated vigorously. Over the subsequent quarter-hour or so, you will note varied indicators on the LCD indicating fan velocity, temperature, which section the roaster is on, and the way far into every section. The latter is achieved utilizing 4 little indicators for every section: 25%, 50%, 75%, and 100% (accomplished).
It ought to be famous that there’s something known as “Superior Handbook Management”. It permits the person to regulate roasting parameters on the fly. I’ve discovered no want or want to make use of this, however in case you are , the PDF handbook can let you know all about it. Now quick ahead about quarter-hour or so. You’ll start to listen to the primary crack. After the primary crack, there ought to be a pause earlier than the beginning of the second crack. Most customers will cease the roast for a number of seconds or snaps into the second crack.
Hottop Coloration LCD Management Panel and Button
For those who have been to let the roast go fully by itself, you’d discover that within the final 30 seconds of the roast, the machine will beep, and flash “Plus Time”, which lets you add time to the roast in 30-second increments (as much as 6 occasions). For those who do nothing, the beans will dump into the tray and start cooling. In any other case, you’ll be able to add time to the tip of the roast with a most of 24 minutes whole (21 minutes max AUTO program beginning time, plus 6 further presses that are 30 seconds every).
Observe that though the AUTO program solely permits for a max of 21 to begin inside its pre-defined program, with a customized profile you can begin with a max of twenty-two minutes, and thus the max general time is 25 minutes for customized. Confused? Don’t be. I wouldn’t fear concerning the max occasions an excessive amount of, as you usually would wish to preserve your roast occasions underneath 20 minutes anyway.
One other little security function you could discover because the roast will get close to the tip is the excessive temp warning. If the temperature reaches 414 levels Fahrenheit, the unit will beep, prompting you to hit enter to permit the roast to proceed. That is simply to make sure that a hearth doesn’t get away. For those who do nothing, the beans will dump into the tray and start cooling. Earlier than you begin the subsequent roast, the machine will beep to immediate you to empty the chaff tray, together with a graphic on the LCD. This ensures the person won’t go away an excessive amount of chaff within the tray, rising the prospect of a hearth.
Customized Applications (Profiles)
The Hottop KN-8828P can maintain 10 Profiles (known as “Applications”). One is already pre-set, and can’t be deleted, in order that leaves 9 for the person. Every Program can have eight segments. Every section could be as much as 3 minutes lengthy (with a minimal of 10 minutes and a most of twenty-two minutes). Inside every section, you’ll be able to specify the time, a goal temperature (inside a particular vary after all), and the fan velocity. The fan is especially used to evacuate smoke from the beans to reduce the beans’ taking up a smokey taste. See my base profile for a greater understanding of what a program consists of.
Getting into a program is just a little concerned, however when you get your first program in, the remainder turns into simpler. It’s because applications could be copied from one program to a different program slot with a few button presses. I counsel mapping out a base program on paper (or utilizing my base program) earlier than you sit in entrance of the roaster. This may make it simpler to enter. Belief me on this one.
Taste
One of many issues plenty of dwelling roasters attempt to do is stretch the time between 1st crack and 2nd crack (2 minutes is a pleasant spherical quantity), with a complete roasting time of about 14-19 minutes. Nicely, I’m right here to let you know that this roaster can meet these situations pretty simply. I can not say the identical factor about lots of the dwelling electrical espresso roasters I’ve had over the previous few years. Some are one or the opposite excessive, and typically too excessive (bitter or baked).
I discovered that with the Hottop, I might obtain pretty shiny, shorter roasts for my drip, vac pot, and French Press espresso wants, but in addition get sweeter, mellower, longer roasts for my espresso wants. Whereas I actually just like the Fluid Air Mattress methodology of roasting (present in roasters just like the Sonofresco), the Hottop supplies a barely totally different taste throughout the board. It’s able to barely much less shiny roasts, however nonetheless supplies a roast sufficient for drip, vac pot, French Press, and many others. On the espresso finish of issues, it actually does a wonderful job. Of all of the roasters I’ve owned or used, this one constantly supplies, for my style, a few of the finest espresso pictures ever pulled in my home. What I’m saying, is that for me, I don’t presently really feel the necessity for greater than the Scorching High Roaster.
Cleansing and Upkeep
After each roast, I discover it mandatory to make use of compressed air to blow the big quantities of chaff out of the roasting chamber, chaff tray slot, and all connecting airways. That is in all probability the most important annoyance of all, so think about one other $100 for a good compressor to maintain round.
The viewing window can simply grow to be obscured with espresso oils. The cleansing is easy. Loosen the massive brass screw, and take away the quilt that features the glass window. A little bit answer of Cafiza in sizzling water and a rag, a fast rinse, and the job is full. I discover I’ve to do that each 2 to three roasts, which I discover just a little annoying, however I’m unsure if there may be something that might have been achieved in a different way within the design.
The glass viewing window is superb for watching the event of the roast. It will get soiled simply however can be simply cleaned.
The drum itself is really useful to be eliminated each 5-10 roasts and cleaned with Cafiza answer, in addition to every other particles like bits of espresso beans, chaff, and many others.
The chaff tray can get some muck on it, but it surely too could be cleaned with a Cafiza answer and a rag, however in all probability each 50 roasts could be sufficient.
Inside cleansing is really useful each 3 months. The steps are pretty concerned, so please see the handbook for full particulars. Primarily, it includes cleansing the circuit board and rear fan areas of mud and particles.
The Rear filter is really useful to be modified each 20 roasts. Many have discovered that soaking your entire filter (together with the plastic holder and filter supplies) in a cleansing answer like Cafiza, can prolong the lifetime of the filter. For those who attempt to take away the paper filter part, it may be very troublesome to get it again in, so that’s the reason I like to recommend retaining all of it collectively when cleansing. Please observe the producer doesn’t advocate this, so please accomplish that at your personal danger.
The highest filter is really useful to be modified each 100 roasts. Undecided how vital that is, but it surely in all probability wouldn’t harm to observe this advice, since each 100 roasts for most individuals works out to about a few times a yr.
The principle rear filter can get blocked shortly, and alternative is really useful each 20 roasts.
The remainder of the machine could be wiped with a comfortable cotton fabric and water if mandatory.
Suggestions and Feedback
For individuals who have an sufficient family voltage of 120VAC or above, the next could not make a distinction. Nonetheless, I like to recommend the usage of a excessive amperage Variac (to at all times present the identical, sufficient voltage on each roasting session), and a Kill-a-Watt, which we are going to simply use as a elaborate digital voltage meter, that permits us to precisely learn and set voltage with the Variac on the fly. 20 AMP Variacs could be bought model new for just a little over $100 on the web.
Variac and Kill-a-Watt present sufficient and constant voltage, which ends up in repeatable roasts.
For all operations, every button is backlit, and solely buttons which might be relevant at the moment will gentle up. Very good contact. The LCD itself can be backlit with totally different colours relying on what the roaster is doing. Once more, good use of expertise, truly telling us one thing helpful.
The cooling occurs outdoors the roasting chamber, which signifies that if you determine to cease the roast, the beans don’t proceed to roast very a lot. The cooling cycle on the Hottop is 4 minutes, however the beans are often cool inside about 2 minutes.
Many different roasters in the marketplace have cool-down cycles that take upwards of 10 minutes, which suggests you’ve got much more guessing to do, in order to “coast” into the specified roast degree. Or it’s a must to bypass the producer’s design, by pulling the beans and cooling them externally, thus risking damaging inner elements. I just like the Hottop approach a lot better, and different producers ought to pay attention to this very essential weak spot in lots of different dwelling espresso roasters.
Conclusion
Why do I favor the KN-8828P Hottop bean roaster over different Hottop fashions? Merely put, I’m a espresso geek. I really like with the ability to have a giant color-coded LCD readout. I really like with the ability to program and save 9 applications and have 8 segments for every program, and tweak it all the way down to the final element.
However greater than something, I can confidently share applications with different KN-8828P customers. Each a part of the equation could be quantified – Ambient Temperature, Family Voltage (when utilizing a Variac), Inexperienced Bean Load Dimension, and most essential: the EXACT program that one other KN-8828P person can punch into their very own unit. I don’t suppose you’ll be able to simply do that with different Hottop roaster fashions, just because they lack the particular programming capabilities that this unit has.
At practically $1000, the Hottop KN-8828P won’t be in everybody’s funds. I believe its reliability is what appealed to me firstly. Add the superior programmability, and a cooling mechanism outdoors the roasting chamber, and I used to be offered into making an attempt it. In fact, it’s about how the espresso tastes, so after growing a profile that appeared to work on nearly each inexperienced bean in my stash, I made up my mind this man a keeper. Take a look at the professionals and cons listed under, which can allow you to additional in your determination.
