i recently like last week purchased the I-roast, joined the list and been reading the archives, does anyone have good things to say about the i-raost! does anyones roasting cycles with the i-roast work.seems as though there is nothing but negative responses to the i-roast. should i not even open the box up! now i am really green here and really new to this, i've purchased some books on home roasting, and i'll do trial and error. Beleive me i'll not give up on this! but my question is, does anyone who owns a I-roast heve some cycles that will work, anyone have some advice! Also saw a modified chaff colector i believe on this site, was nothing but an aluminum hose, one was into a bucket...anyone know where that link was? also s there a wabsite or book that explains roasting lingo, such as chaff ect.
Thanks Shawn

Shawn, relax, easy -- if your I-Roast is working properly you will have a good experience. Try this 2 minutes at 325; 3 minutes at 375 program out to 10 for 425. It appears that I-roasts run at different temps, but on the average, for a City Plus roast it will go about 3:30 into the 3rd stage. Full City 4:00 Vienna up to 6. But let your senses tell you. This is not a bread machine. You will have to acquire the skill to roast, and that is what makes it fun. Various beans will roast differently. As for the vent, I use a dryer hose. I bought a drier fitting and cut a whole in a board that I cut to the width of my window. I closed the window on the board and attached the dryer vent to the fitting -- presto outside venting. This is a great roaster. I use another method as well, but I wouldn't be without it. Good luck. Relax -- there will be a learning curve. Dave E |
Hi, I started roasting green coffee beans a little over a year ago. I started roasting my beans in a Toastmaster popcorn popper. I found this to be time consuming, so I looked into buying a roaster. In August I purchased an I-Roast, I love it. I bought it from Sweet Maria's. At first I roasted using the preprogrammed temps, the roasted beans were OK. About a week later I started roasting per the recommendations from Sweet Maria's. My roasted beans come out great. You can go to Sweet Maria's web site (_info's.com_ (mailto:info's.com) ) to get the roasting temps. they recommend for the I-Roast. I live in North Carolina, so it's pretty cold. I keep my machine in the house when not in use. When I'm ready to roast, I take my machine from the warm house into the garage. I put the I-Roast in a box when I'm roasting to keep it warm. I'm having lots of fun roasting and drinking the different coffees from all over the world. Good luck.......Dorothy |

The best advice I have is to follow something like the profiles in Tom's tip sheets but to max out the time setting in phase 3 and turn on the cooling cycle manually. This has helped me roast in a cold basement where the cold intake air has extended the roasting time from Tom's profiles. Also keep a roasting journal to help reproduce the profiles that work for you. Steve W. |
Shawn, I, also, have been roasting a little over a year. I started with a Toastmaster and in June got my iRoast. Although I think there are some improvements that Hearthware could have and should have made to the roaster, I am one of the "happy" people. I use Tom's recommended roast profile (modified a little) of 2 minutes at 340°, 3 minutes at 390°, and 6 minutes at 450° and then I watch, listen, and smell carefully and stop it manually by starting the cool cycle. The only modification to the chaff collector that I have made for regular coffee is a little wad of tin foil that I place in the center of the chaff collector so the screen lid will hold it down tight. I roast in my garage, with the roaster vented through a window using some flexible vent hose and a clothes dryer vent that I rigged to go into an open window (when I roast). I live in Virginia and right now it is rather cold. I found that "preheating" the iRoast with a hairdryer for about 15 seconds works to overcome it's refusal to operate in cold temperatures. I also use the dog bowl/heat gun method of roasting, which has become my preferred method, but I still roast at lewast one batch a week in the iRoast and I think it is a good machine. You're not gonna find out till you take it out of the box and roast some coffee. Go for it! Don't just plug it in and walk away. Watch what is happening - not just for safety, but for the learning experience. Watch, listen, smell, learn and most of all, enjoy the fresh roasted coffee that you will start producing.

Thought I would weigh in on the i-Roast, because the more I read, the more confused I get... It's hard for me to tell from all the reports I've read whether Hearthware is shipping lots of bum roasters or if lots of home roasters are just not doing something right. My roaster works fine at low temperatures, but once I program in anything over 380-390, I lose control of the roast entirely; it takes about 30 seconds or so to go from city to vienna, with no differention between 1st and 2nd cracks at all. I know, I know, program in lower temperatures, you say. But there are two problems with this. First, if I can't use temps higher than 380, then what's the big deal about having a roaster with temerature control? I though that was the point of the i-Roast, to have this control. Second, clearly there are i-Roasters out there that CAN handle higher temps, so what's the deal? Why is it that some i-Roasters seem to "handle" higher temps but others cannot? My first thought was that the chamber was heating up too fast because of chaff. I, like others, have a loose-fitting chaff collector ring that let chaff sneak out and clog the mesh screens on top. So I folded a picece of foil to wedge in between the collector ring and the lid. The up side is that this keeps much of the chaff from blocking the screens... The down side is that it does nothing to give me more control over the roast. I still can't use temps higher than 380-390, and I still can't prolong the 1st-2nd crack interval. This makes no sense. Tom says that 350 F for 2:00 min, 400 F for 3:00 min, and 460 F for 4:30 min gives him City to City+. But this profile on my roaster gives me Vienna/French less than 1.5 minutes into 3rd stage. How can this be? There's no way my voltage is higher than his, so either there's something ELSE I'm doing wrong, or there's a problem with my i-Roaster (and to make things even MORE complicated, the themo readings are consistently low relative to my profile temps -- I know this isn't a "problem" but it does suggest my unit isn't running particularly hot). Furthermore, I've tried cutting back on the beans... From 150g to 135g to 120g. This makes a teeny weenie difference, but not much. And frankly, if I cut back the amount of beans any more, what's the point of using the i-Roast?!? My HWP did 75-80g no problem...the appeal of the i-Roast was its x2 capacity! Okay, enough ranting. Am I crazy? Am I missing something? Oh, forgot the kicker: I have had the same problems with BOTH i-Roast units I've tried...the one I bought from SM and the second HW sent me as a replacement. So again, what's the deal?!? I appreciate any/all input y'all may have on this. Aaron S.

Your i-roast sounds exactly like mine. Using Tom's suggested roasting curve (340 for 2 minutes, 390 for 3 minutes, 450 for 4-6 minutes), my roasts reach the Vienna stage about a minute into Stage 3. If I let the roast reach 5 minutes into the 3rd stage, it's charcoal. I performed the chaff collector mod and that helped cool things down a bit, but it didn't make much of a difference. By the way, my house's voltage varies from 118 to 121. In attempting to slow the roasting times, I've tried using much lower temperatures, but the roast always develops too fast if the temperature is set over 390. But if I keep it below 390, the roast stalls out at about city stage. The i-roast seems to have two fan speeds: fast and slow. When the temperature is set below 390, then the fan speed is fast; if the temperature is set at or above 390, then the fan speed is slow. On my i-roast, there is no difference between 320 and 380; and there's no difference between 390 and 450. It's as if the variable temperature control is meaningless. There seems to be just two settings, separated by the 390 degree threshold. The problem with this behavior is that it is very hard to control the roast. Assume I adopt the following profile: 350 for 6 minutes and 400 for 4 minutes. (I am using 350, but, as I wrote above, the roast develops the same at any temperature between 320 and 380.) So, the roast develops fairly nicely for the first 5 minutes, bringing the beans right to the verge of first crack. When the second stage kicks in, the heat is too high: the roast charges right through first crack and into second in a couple of minutes, with little or no discernable pause first and second crack. One thought I've had it to muck with the thing so that I can control the fan speed separately. As I understand it, the i-roast doesn't vary its heat output at all: it just varies the fan speed to change the roasting temperature. If *I* could control the fan speed, then I wouldn't have to worry about figuring out the i-roast's mysterious behavior; I could just make the necessary changes during the roast. -Brent --- "Aaron S." wrote: <Snip> Do you Yahoo!?

Folks - there were some changes to the i-Roast default programs a
while back and I was slow to respond ... ie make tip sheet changes.
That wouldn't affect the custom program settings in itself, but the
newer i-Roast chip varies air speed to change heat in a different
way. The first generation would fluctuate air speed from high to low
at 10-15 second intervals. The newer generation varies airspeed in a
continuous way, not short intervals. This DOES affect the custom
programs, I think. In a way the changes are good, and if I might be a
little self-centered here, I think Hearthware actually took my basic
custom program, and made that the Preset 1 on the new machines.
But I need to make an apology ... I wasn't aware of the change, I
didn't make Tip Sheet modifications to acurately reflect the change,
and my online review (well, the part where I have the datalogged
temperatures) is based on the prototype still. I put a lot of work
into things, and that sorta backfires when something changes because
I basically have to take a day out from everything else and do all
the work over again. I really need to re-do my tests and do some
comparative cupping with the results to "index" them both to the 1st
generation i-Roast and to the other roasters - I will do that SOON!

I guess the issue isn't necessarily what the temps say, but what they produce. If dropping stage 3 below 390 gives you the desired response, great, I wouldn't worry about the numbers, they are relative to your roaster. |
You know Tom, I really appreciate the work you do, on this and everything else, and I guess it is what puts you a step or five above the rest, but frankly you have nothing to apologize for. It is Hearthware that should be making these tip sheets, and suggested programs and how too's on THEIR MACHINE. It really isn't your responsibility. And besides, there are prototypes out there that use your original info. How are people to know which "model" they have. I have never been burned by Hearthware, but I don't like them. rant over.

Tom, I want you to know how much I appreciate you tip sheets. It is what makes your site the most comprehensive wonderful spot to visit. I visit your web page every day. Thanks for all you do. It would be nice if Hearthware and other vendors do what you do, but the home roaster mentality is not to accept anything without trying to make it better. Our is a tinkering mentality. Our tinkering and your reports actually help the manufacturers, obviously. Thanks for helping. |
Here, Here! We all agree!
Kudos Tom...
