I am new to roasting. Being a technical person I am deep into measurements and treating each roast as an experiment to document and analyze.

I looked around for logging forms or software and couldn't find any so I set about writing my own. The basic log I did was an MS Word form. I modify it as I want.

http://www.richhelms.ca/richhelms/pix/RHCoffeeRoastLog.doc This is my roasting log. I cam quickly note my readings during a roast, then plot the results with software.

The real thing I wanted was a graphing program. I am a WordPress heavy so I set about looking for WordPress plotting support. I found an amazing package called JSXGraph but it was not trivial to plot a roast with it. The solution was to extend the package to add commands to plot roasting temperatures.



[ROAST:6.5:72,74,89,97,119,145,158,181,204,220,242,244,270,289,289,287,277,262,250]
[COFFEE:Mexican FTO Decaf]

The syntax is [ROAST:roast_time:temp_at_0, temp_at_.5, ...]
[COFFEE:Name of the coffee]

This is the markup to create this plot. The square box with details is shown over a point when you point to it with your cursor. The brown dots indicate it is during roast, the blue temp during cool down.

Now I am using an IR temperature device so I know I am getting a distortion from the glass but it is consistency I am looking at.

If anyone would like the software just go to http://webmasterinresidence.ca/webmasterinresidence/?cat=40

This is a WordPress plugin and it is free. I mainly am looking for feedback from other roasters on ways to enhance it.

Not that's it's what you necessarily want, but you might look at BehmorThing. If you ignore the name, you'll find a configuration option to hide all the Behmor features and it has built in temperature logging and graphing.

And if it doesn't do what you want, you can always ask and I might change it so it does.

And it does require Windows, so that might put it out of contention.

Thanks. That is a pretty cool program. It is definitely tuned to the Behmor 1600 but this is a nice program. I will look deeper into it.

Just make sure to check "Hide Behmor Heatures" on Utilities/Preferences and all the Behmor stuff vanishes.
