No, what's unthinkable is... no coffee. ;-)

Build a shed....  :P

I am thinking sod huts are big in Canada.

Awesome. In the image above, it looks like my garage has a chimney to vent the roasting fumes when the temps drop to -80 degrees.

If it got below -20 ...snip... I've roasted in temps below -40.



Is that Canadian degrees? Seriously If I hadn't joined the military which had me moved to New Jersey and stayed in cold places like Alaska in January etc... I would never know what cold weather really means. Sucks.

Uhhh Shaun, I don't think that is a Garage. I think it's a duplex, and the small side is where Grandpa sleeps. They don't have Garages for horse drawn Carriages, they are called "Barns". But I think this picture is actually from Utah very recently, don't let the old clothes and lack of technology fool you.

Hey, it's my dream home don't go calling it a duplex. I like to think of it as a bungalow with attached garage and a view. ;-)

It is actually in Saskatchewan. I wouldn't offer staylor a fraud.

I'm still roasting in the house...... at least until I get kicked out to the garage. I'm using a Gene Cafe so the smoke has not been too bad. That being said..... snow is part of reality here in Canada.

I have a question about higher drop temps on the Hottop. How long does it take you to get to 300 F? I thought the standard 6 min was an important point to maintain in the roasting profile.

Recently replaced the "P" panel with a "B" panel and added environment and bean mass temperature probes.

Very cool!  I have the P, and sometimes wonder whether a B would not be better.  I have asked Michael at HotTop to set up a forum on their site so HT users can share their profiles for different beans.  The bean mass thermo seems to be very valuable, but why did you install another environmental thermo?  Is the installed thermo not accurate enough, or do you want the USB from your datalogger?

The standard thermocouple is coupled too closely to the rear wall temperature, so it varies with outside air temperature and whether the roaster is cold or hot.  It tracks well with the profile, so it serves its purpose for the stock model, but it is not an accurate measure of the environmental temperature driving the beans.

I had a little trouble this morning--was getting some goofy things with the environmental probe--its temperature went lower than the bean temp with the heater on (and bean temperature rising after 1st crack was concluded).  I knew it was off.  Pulled the TC wire out from the tube a bit on both probes, and the next three roasts tracked perfectly.

Here's what makes having temperature and full control great:

First two roasts were intended to be FC/FC+ with a Triple-pick Sumatra.  Both went between 4-5 minutes from first crack start to end of roast, with end bean temp around 440.  Last roast was an Ethiopian Natural Sidamo, which I pulled at 420, but with the control and temperature monitoring, I still had over 4 minutes from start of first to end of roast, without stalling.

"Vincent!  We happy?"
"Yeah, we happy."

I'll have a few profiles posted later today.
