Also learned that the building that used to have the local furniture store has been bought by a martial arts place. I'm optimistic about that development and expect them to be good for my business (the parents can have a coffee while the kids have their lessons, happened a lot back when we had a dance studio a similar distance away).
Some example data that I pulled together for an upcoming coffee roasting class. The top section shows the temperature of the coffee and inlet air, from which you can get a good sense of the control strategy in play. Below that is rate of change of the coffee temperature. Then below that is a visual spectrum (roaster camera) approximation of the Agtron gourmet scale roast level over time which isn't saturated out of range at the start because this is a decaf coffee which already starts out brown.
I haven't done all the web site updates that are needed yet, but the new coffees from Yemen, Java, and Kenya are up for sale along with a Mocha Java Blend. https://wilsonscoffee.com/coffeelist.html
