In my opinion, yes. It's worlds apart from what you and I and Dustin played with at SF MOMA.

Paul shared this comment; Craig's wife is of small stature, so they tested the redesign with her, seeing if she could grind thru a light roast without feeling it was too hard. She apparently was happy. Take that with a grain of salt, or come over across the bridge Thursday or Friday and I'll let you give it a few takes. I'm sure Paul and Craig would appreciate input from others as well. You and I represent the polar opposites in ergonomics, body size wise, so it would be a good observation.

Good review...thanks! Looks and sounds very promising with the mods.

Man oh man this looks promising and I feel encouraged. Might just have to hock my Mazzer Mini E for one of these.

I admit to not knowing anything about hand grinders but if the speed of turning affects the grind, does that hold true for the other hand grinders out there? How much change in speed is required to change the grind? IOW, how easy is it to get consistent results?

Hi Tom

We'd love for as many people to try our grinder as possible. We don't want to impose on your hospitality, so it's entirely up to you as to how many you'd like to host.

kind regards,

Paul & Craig

I'll be timing my pre-shot routine over the next two days when I'm off. But after this mornings attempt, I believe it took less time to get the shot ground and prepped and into my PF than it does for me to single dose my K-30 Vario. And that's without going back and re-weighing the Vario. If I were to do that, I know for certain that the electric grinder would take longer.

I've had a lot of thoughts running around in my head all night and I've got tons of emails to respond to. I'm running around at work today, but when I get a better chance, I'll go over those inquires as well.

This will take some time and practice to be able to answer with any certainty. So, it's too early to tell. My personal take is that I'm not going to always be cranking as fast as I can. It's easy to settle into a normal RPM or cadence and I've been using that for the most part. I've only pulled 3 shots where I cranked faster, and that's very relative, it's still incredibly slow RPM's when you think about it.

I'll say this much, even with my tedious WDT, I'm occasionally getting donut extractions, like this morning. They dont last thru the entire extraction, but for the first 3rd when it likely counts.

Why do you WDT with the monster conical? If you have to use WDT something is wrong.

I find Tom's initial results very interesting, because they suggest that grinder speed affects fines production. This isn't something you can necessarily compensate for by changing the grind setting or loading the hopper differently, which in turn suggests that grinder speed may be very important -- at least for conical grinders.

My recollection is that there has been a bit of discussion on this board about the effects of grinder motor speed. While I don't believe that rigorous tests have been conducted, the posts I've read tend hold that lower grinder speeds are better. Two of the top-rated Titan conicals, the Robur and K10, run at relatively low speeds. Without spending a lot of time (that I don't have right now) to search and read those threads, I can't say whether the benefit is supposed to be in flavor, consistency or both. But if the percentage of fines is partly a product of grinder speed, we have something that needs further investigation.

As for the trade-off in preparation time between motorized and hand-operated grinders, my calculations show that hand-grinding with an HG One wouldn't take materially longer than the current bump/grind/sweep/clean routine I go through when single-dosing with my K10. The advantage would be even less retention and a much quicker cleanup (the part of my routine I like the least.) IMHO, once the HG One is fully optimized, the difference for those who single dose will simply be in the muscle effort required.
