1) From: Ken B
Well, this is not earth-shaking or anything, but I was thinking about it 
and chuckling to myself, so I thought I would pass it along.
As all of you know, I am having one heck of a time with hearing first 
crack on the i-Roast 2, let alone 2nd crack.  So after looking at some 
pictures on the SM website, and tasting a roast I THOUGHT was FC+, yet 
exhibted what Tom said was City down the line, I thought, ok, the roast 
is not getting hot enough. (bean mass temp at cool was 444 degrees)
Sooo, I have 90 grams of Sumatra Aceh District left in a sampler bag, 
and 90 grams of Indonesian Flores Bajawa Highlands.  I decided, ok, in 
an air roaster, the 180 grams should push the temp a lot. (based on 
reading this list...not on actual experience)  Throwing caution to the 
wind, I programmed a new profile that should ramp fairly high after a 
slower first crack.  (If I could hear it, I would confirm it...but since 
I cannot, I assume first crack at a bean mass steady temp of 408).  The 
profile was 3 min @ 350, 2 @ 370, 2 @ 390, 1:15 @ 405 and 4:30 @ 445. 
(yes, I was trying to be sure they made it to 2nd crack)
I started the roast, and I THINK heard first crack at 6:46 remaining, 
with an internal temp of 408 and a bean mass temp of 416! (this sounded 
a bit high to me)  Anyway, no second crack was heard, but I cut the 
roast at 4:09 left with a bean mass temp of 472.  Roast looks good, 
smells good.  One type of bean shows definite lag over the other as 
about half of the beans where a shade lighter than the rest.  (I have no 
idea which lagged or lead)
So, I decide I need a cappuccino, and grind 18 grams as fine as my 
grinder can grind them, and throw them in the Gaggia.  They have rested 
a total of 3 hours at this point.  Gaggia pulls the shot in 26 seconds.  
I taste the espresso.  WOW!  I think it is the best I have had from my 
Gaggia.  Chocolate, soft, full mouth feel, no acid or bitterness at all, 
with a hint of spice like cinnamon or clove with a nice creama.  
Resisting the urge to just drink the shots, I steam the milk and make 
the double shot (well, a bit less since I tasted the espresso) 
cappuccino.  Again WOW!  The best cappuccino I have had from my Gaggia, 
and one of the best I have ever had! Soft, subtle.  Chocolate syrup, 
mellow, again, no bitterness or acid.  The nutmeg I add to mine, along 
with raw turbinado sugar, enhanced the chocolate and spice already in 
this roast.  Absolutely wonderful to my tastes!  Granted, I am not an 
experienced connoisseur of fine coffee or espresso, but this is WHY I 
bought all of this stuff and put up with the frustration!
Frustration? Ask me about the other 10 roasts I have tried to re-create 
the molasses in the first roast of the Sulawesi Enrekang, which all 
follow a very, very similar temp curve to each other, and is different 
from the first.  And the molasses is toned down in each and every one of 
these.
Heh, so experimenting with "leftovers" has provided me with a roast I 
will try to recreate...though that seems almost impossible in the 
i-Roast.  I don't care what you guys say, I still think there are goat 
sacrifices involved somewhere in this arcane art!
Best Regards,
Ken B

Congratulations! My only question is why resist the straight shot, espresso
in it's purest form?

Ken,
 
You should try getting an inexpensive pair of noise cancelling headphones (=
I have a pair of Sony's that cost me, I think, $30).  It's made it much eas=
ier for me to hear 1st crack with my iRoast2.  Good luck and enjoy the KenB=
lend.

Great story and details, Ken.  I'm with you - my iR2 experience has been too
many batches fall to City (all the stories about over roasting on the iR2
may have me cutting the roast too early).  I cannot hear the cracks, either
- even with noise canceling headphones.
I'm going to try your 'goat roast' profile with some of my leftover baggies.
Cheers!

Good luck Sean.  Please let me know the results. 
I am really not happy to hear that the noise canceling headphones didn't 
help you, since I just ordered some to try them.  Heh, this started out 
as a way to get good coffee at a decent price, but has turned into 
getting ok coffee most of the time and excellent coffee sometimes, but 
at a very high price.  2 roasters, electronic thermometer, new grinder, 
noise canceling headphones, a scale, a new french press, ~20 lbs of 
green beans, etc., etc.  Ah well, maybe all these notes piling up will 
help at some point.  I guess I needed a hobby anyway. ;-)
Best Regards,
Ken B
