Topic: Behmor roast in Brazil - request for advise (6 msgs / 227 lines)
1) From: Pieter Sijbrandij
First, thanks to you all for your recommendations made a few months ago, and
thanks to Derek of SM  for shipping in time! Sorry I did not manage to meet
John in Mexico. I’ve been too much running around. However I managed to p=
ick
up in Miami my brand new Behmor roaster. I forgot to tell Sweet Marias that
I would export it to Brazil so got the 8 1lb samples which I then “forgot=
”
to take out of the box. They are now locked away together with my wife’s
jewelry!
 =
I know SM and Joe Behmor recommended NOT to buy it due to voltage problems.
But the projected 220V model will probably be for the European market which
is 50 Hz and here we have 220V 60Hz…  So I decided to work with a convert=
er
and risk it. Your passionate discussions on the Behmor are too convincing
not to go for it and sticking only with my “ball roaster”  and a gas st=
ove
is not enough fun.
 =
I am amazed by the ways all of you experiment with the Behmor, but for the
time being I try to stay as close to the manual as possible as I had to void
the warranty and have still so much to learn. However converting 220 results
in 110V (I measured it) so I will have a heating problem (and being winter
the room temp is not favourable either). =
 =
My first test of ½ lb at P3 (see manual: brazilian low grown) adding max
time during the third leg  did not reach the first crack. Reducing the
weight did make me get the first crack but not yet to the second. Reducing
it even more to a quarter did not change considerably the results: City or
City+ (don’t know how you actually figure out the difference even using t=
he
pictorial guide). =
 =
The cup was OK but not great (acidity a bit too pronounced (citric notes)).
The cup wit the AP was better than with my Mokapot. I would like to go to
Full City+ or even Vienna as most Brazilians like dark roasts and I will
have to give away a good part of my experiments. I know the coffee is good
as it participated in the Minas Gerais competition (not a prize winner, but
4 years ago it did). =
 =
So before going on,  please give me some advise on what to do (and what NOT
to do) to compensate for the lack of voltage (if possible at all). I guess
there will be a time delay but not a maximum temp problem (or is the
thermostat also voltage sensitive?). However, I would like to avoid baking
the coffee. Reduce time in first legs and increase in last leg? Preheat? Put
½ lb  at 1lb P1 and hit cooling? …………
 =
As I have over 30 pounds of this coffee to test with (that’s the advantage
of living in Brazil and having producers as friends) I want to save my
SM-samples for after the steep learning curve I know I have to go through.
How best to store for the time being the sample packages as I cannot order
those fine coffeees you all talk about?
 =
Add-on: I will be traveling for work to Peru the end of this month. Any
coffee place I have to visit in Lima or Piura?
 =
Fourth and last… happy as I am now, I wonder whether I am the first Behmor
homeroaster in Brazil.
 =
Thanks a lot! =

3) From: Bonnie Polkinghorn
Hello Pieter,
My advice would be to put in 1/2 lb,  set it to 1lb, P1, 20:30 (which I
think is the max time for P1)
Then, see how long it takes to get to start of 1c, end of 1c, and if it gets
there, to 2c.
Then, you can start to use P2, P3, etc. because you will have a sense of how
long it takes to get to 1c on full power, and time your roast appropriately.
Good luck,
Bonnie P.

Pieter,
By using P3, with the system set to more coffee than you load into it (1/2
beans at the 1 lb setting or 1/4 lb beans at the 1/2 lb setting), you're
forcing it to do a longer and slower temperature ramp than you really want.
Instead, I would suggest the following:
   1. Use 1/2 lb of beans, press 1/2 lb, P3, C and write down what the time
   is.  I believe it's arounf 14:00 (don't have machine or manual in front of
   me).  Think of this as the recommended time to roast to a City+ for 1/2 lb
   on this profile.
   2. Now, press the 1 lb button.
   3. Hit the "-" button until you get down to the recommended time that you
   wrote down on the 1/2 setting (~14:00).
   4. Hit start.
   5. Then hit the "+" until you get it up near to the max time allowed.
   6. Watch it like a hawk and hit "Cool" when you reach your desired roast
   level
This will give you the recommended temperature ramp profile for a 1/2 batch
(because you started with the clock at the ~14:00 setting).  By hitting the
"+" after you start the roast, the extra time is all added to the last
segment, which is at max temperature.  Once it reaches the max temperature,
it will keep the roaster there until you hit cool, which should give you
plenty of time to get to FC, FC+ or whatever you need.  You need to watch
it, because your chances of a fire go up with so much time at max temp.
Good luck!

5) From: Pieter Sijbrandij
Thanks Seth, Bonnie and Paul, I just tried Seth's P3 formula. I works quite
well. Voltage 106V with heating elements on (early evening power drop?) You
were right with yout 14:00 min. Adding up afterwards I got to a time max of
19:30. I watched it like a hawk but reacted like a snail. Should have
reminded myself of the coasting. First crack at 15:40, second at 18:30. + 10
sec into 2nd gave me as result: Vienna.
Now I can sleep well and send a mail to Joe Behm that even with a
transformer his little wonder makes people happy. Will cup the coffee
tomorrow and follow the suggestions of Bonnie and Paul the coming days.
More tips and instructions very welcome.
Thanks again! 
Pieter

Pieter,
I'm so glad to hear it's working for you.  Now, how do you prepare your
coffee?  Cafezinho? :)
