Back when I was living in Ft. Worth, and had a friend with a coffee shop / roastery there (met through CoffeeGeek), we'd have local meet-ups every so often. Some of the highlights of those meets were sharing our home-roasting coffee gadgets, doing some experimental roasts on the big Probat, learning how to really "taste" our coffee from a guy who was a professional sommelier (wow, what an eye-opener!), helping a guy refurbish a $25 garage sale Silvia find that had seen better days, and sifting through grinds and analyzing particle size from all our different grinders.
Back then, I was using an early (Baratza-made) Solis Maestro Plus for most everything, and it compared quite favorably to some far more expensive mills. Might not have been as good as a dedicated drip grinder or a dedicated espresso grinder, but it was pretty dang close and could do both! It was cool to see the physical partical size distribution (using specific micron particle size filters to sift the grinds, I think they came from the medical or chemical industry) versus what we could/couldn't taste in the cup. That SMP "died" a few years back while I was out of town on an extended business trip, so I called up the
owner of Baratza, and we chatted for a bit. He and I had talked several times in the past about engineering and design of these grinders, back when they was still sellling under the Solis brand. Not that he's a close friend, but he is approachable, and likes to talk coffee and about the engineering of his grinders. Especially around that time when he had a new grinder out (the Vario) and some cool new designs in the works (what became the Sette). Long story short, to replace my "dead" SMP, I wound up with a Virtuoso he had just finished refurbishing himself, and that's what we still use. Turns out, my old SMP actually had an electrical switch inside go bad (it wore out), and after getting a new one from Kyle at Baratza, the grinder still works!
It's now our back-up grinder and lives in the pantry most of the time, just in case...
