Here are the graphs. B-1 has a 15.71% mass loss and the ground coffee measures 53.7 on the Agtron gourmet scale. B-2 has a slightly higher 15.86% mass loss and a slightly lighter 53.9 degree of roast. Those post-roast measurements are closer than some roasters get trying to follow the same plan but these are clearly very different roasts.
Going through the roasting data for tomorrow's class and I'm really excited about the B-1 and B-2 pair. I roasted these to the same ending temperature but according to extremely different roasting plans (B-1 is a pretty extreme profile), ending up with ground degree of roast and percent mass loss measurements that are almost identical, so it's a great example to show the limits of using those numbers as a proxy for consistency. I think I need to add another slide for this pair.
The covid rules are playing hot potato. First the state governor's office came out with orders which the courts struck down, then the city mayor's office came out with orders that basically put them back and the courts struck that down, so the alders turned it into an ordinance to put it back and I'm assuming someone is gearing up to challenge that in court.
Last night I finished up a first play through of Deemo Reborn. Overall I enjoyed that. The puzzles were pretty easy for the most part and some of the ones that could have been less obvious provide alternative clues if you're attentive. The rhythm game sections didn't block me from making progress, though that likely will stop me from getting the platinum trophy. Haven't tried the VR mode yet.
It looks like I have a couple repeat attendees in my next class. I'm hoping that's more of someone in a company deciding that this was a useful training experience and sharing that with other people they work with and just re-using the same attendee information and not people failing to realize that they signed up for the same class twice. It's not uncommon for people to decide they want to re-take a class from me, but that's usually 4-12 months later, not 1 month later.
There's still a little time to get in on that. Participants in the US get a quarter pound each of 10 different roasts of the same coffee (5 different ending temperatures, 2 different roasting plans to get to each of those end points) plus a pound of the same coffee unroasted so the price is surprisingly low even if you just wanted to drink the coffees and had no interest in my lecture. (this is what sponsors are for, thanks Pacific Barista Series)
Today I'm roasting the coffees for my next online workshop. It's a smaller group this time so I'm doing smaller batches.
