Subject: bean amount for I-Roast2?
Hi,

I have bought an iRoast2 to start roasting my own coffees. So far I
have roasted only two batches. First batch was a little burned, but
second batch seems to be better.

The beans I have roasted are Indian monsooned malabar.
My question lies in the amount of beans that one is to put in the
iRoast2. The manual states that no more than two cups should ever be
added, and on the other hand all information I ever see is to use
consistant amount of 150g. Two cups of malabar amounts to 105g.

For tha last batch I used profile 10 from Randy's site, but had to stop
it at the end of stage 2.

It looks to me as if the 105g of beans are not sufficient for that
profile.

How can I improve?

Thanks

Monsooned arabica Malabar is a peculiar coffee.
Density of this coffee is less than "normal" arabica.
So 2 cups is less than1`50 grams as you have noticed.
This coffee will roast much quicker than "normal" arabica's so you have
to watch roasting process.

I suggest use 2 cups and use preset 2, but start watching after 7
minutes roasting process.

Hi I am using the I Roast 1, but most of what I have found prob
applies o the Mk2 as well.
The beans I am currently using are an Indian Arabica with a small
percentage, about 10% of Indian Robusta used with them. I have used
other beans too with a similar result

Like the instructions say, I never use more than 2 level cups per
roast. This seems to work well, unfortunatelly the built in profiles
dont work. Using them seems to get a consistently burnt roast, however
this could also be related to outside air Temperature as I have found
that that makes a huge difference with the normal roast I now use.
As a rule, I roast outside due to the large quantity of smoke, and the
even larger quantity of trouble I get into if I roast indoors. When I
roast outside, I now make sure that the air temp is warm, ie, in the 18
degrees celcius + area at least.
The roast I use sounds a bit unusual, but it consistently gives a med
to dark roast bean with a lot of oil on the bean, As long as it is warm
outside..........
My roast times are as follows,
460 deg F ( 240Celcius) for 2 minutes
410 deg F (210Celcius) for 3 minutes
450 deg F (230Celcius) for 2.5 minutes
Way shorter than the profiles built in, and hotter but it seems to
work....and does get into the second "crack" if you listen carefully
I just cannot overstate tho how critical the outside air temp is, if
its a cold day, I just bite the bullet and roast indoors.
I also find that max oiliness is usually obtained some hours after
roasting is complete.

Hope this helps, definitely woth trying tho, please let me know if you
try and what result you get

Hi JulesG,

I converted the fahrenheit into celsius as mine is a European version.
What supprised me is that in the first stage of 320F (160C) iRoast2
measured 375F (190C) after a couple of minutes. On my next roast I will
try to read the temp every 25sec to establish the curve measured by
iRoast.

I beleive I got a decent roast, but I tried it as French press coffee
this morning and found it quite sharp. My wife told me that she didn't
like the first taste, but rather liked the after taste. The beans were
not yet 24H of the roast.
I believe to have read somewhere that the fourth day is best day, but I
do not remember where I read it.

In my iRoast I hear the first crack easily, but I never heard second
crack.

If you do find a good profile for Malabar, I would greatly appreciate
if youd send it to me.

Thanks.

Mick,

I have roasted a blend that contains monsooned malabar using the very
same profile. I used 140 grams and stopped it at 12:30. I suggest you
wait at least 3 days to let it rest.

Your roaster may behave differently from mine. Work on color - don't
let it go too dark. My roaster was indicating 395 F. at 12:30.
Unfortunately, I was unable to hear the cracks.

Good luck. My coffee was very nice.

And futhermore, is it safe to add 150g of malaber to the iRoast2?
For what I see the amount of beans can disrupt the circulation if to
much is added.

Is Indian monsooned really so heavy compared to other beans?
