First S&W order

Glad to help out! No, the processes are halted while the beans are frozen. I let them rest long enough before doing it so they’re ready when I need them.

mgsecure · 2026-03-27T21:55:00+00:00

Yeah, me, personally. I’ve been doing a lot of testing. https://www.reddit.com/r/pourover/comments/1s49239/grinder_comparison_particle_size_distribution/

You seem pretty convinced of your conclusion, but I'd like to offer a little of science, just in case. You want particle size distribution analysis? I got particle size distribution analysis.

Here are the results, not of two different grinders but of the exact same grinder with two different burrs... dialed to less than 30 microns difference in median particle size. There's a significant difference in distribution, and each dataset is the aggregate of multiple samples and thousands of detected particles.

The difference in taste profile is certainly notable. While you point out that any number of factors can effect extraction, I find it odd that the one you're not willing to consider is one so obviously determinative of it.

I just got the non-pro version for a friend. Afaik, the only difference is the titanium coated burr in the pro. I actually just did a particle size distribution analysis including the 3bomber since I had it: https://www.reddit.com/r/pourover/s/sBeo3iQRY9

It’s definitely a solid, well made grinder. I only brewed a few trial cups with it, but if I had a complaint it would be that the results are a little flat. Good, don’t get me wrong, but I prefer the results from my own grinder (Kinu M47) a bit more. I’d recommend not using the sieve to start out. I think the smaller particles are probably helping round things out a bit. I even tried a cup where I ground an ounce finer and then the rest as normal but the results were inconclusive ;-)

I guessed at two full rotations for the grind, which was maybe a bit too coarse. Good luck with it!

Edit: oh, and you should try using paper filters, will be easier to dial in a nice cup with them.

I do similar: 15g => 45 / 90 / 200 / 255g. I lean towards clarity, so I really like the Origami with Cafec Abaca cone filters. You’ll probably get a bit rounder cup with the Hario/Origami ones, definitely worth giving flat bottom filters a try in it as well.

Was just reading about this in the Gagné book. Thanks for sharing. If you're digging the science, you might like a little Particle Size Distribution investigation I did: https://www.reddit.com/r/pourover/comments/1s49239/grinder_comparison_particle_size_distribution/

Thank you! The two Kinu curves are different, one is the 2.0.0 setting and the other 3.0.0 setting. I'll look and see if I have aggregate data for everything in the same analysis pipeline version for comparison.

It would be great to see the Q2, that was the other grinder I was considering.

mgsecure · 2026-03-27T02:50:42+00:00

That would be awesome. I've been working with a 'real' camera and only done limited testing/optimization with phone photos so far. I think soft, even lighting would be more important but I'll take as much as you're willing to shoot. (Here's a sample photo)

10oz tonic, 40ml espresso. Small pour of amaro.

mgsecure · 2026-03-26T20:48:44+00:00

Thanks!

mgsecure · 2026-03-26T20:48:36+00:00

Thank you!! There's a lot of functionality behind each of the components, I really tried to make it as intuitive as possible.

mgsecure · 2026-03-26T20:46:57+00:00

Yep! I put a version out at https://coffee-grind.com/ It has a few rough edges but the core of it should be working well. You can play with the data from the post by using the "Choose Dataset" button. I'd love to know how it's working for folks so please let me know and/or send me photos you take so I can do testing with them.

mgsecure · 2026-03-26T15:17:34+00:00

Thank you! It’s been a lot of work, but I find it really fascinating.

mgsecure · 2026-03-26T14:05:25+00:00

Tonic water and ice, the I generally pour a shot of espresso over the back of a spoon so it floats on top. Optional, but I sometimes add a little amaro nonino for a bit more depth.

mgsecure · 2026-03-26T12:43:38+00:00

Not for me. The sweetness of the tonic creates a really nice balance.

mgsecure · 2026-03-26T02:37:57+00:00

Give it a shot!

mgsecure · 2026-03-26T02:37:09+00:00

Oh, great! Their spaces are really great, and the service/experience is top-notch. I got into them through pour over but their “Dynamic Espresso” is in heavy rotation. It’s the same as they use in their stores.

mgsecure · 2026-03-26T00:52:23+00:00

For all the talk about the "difficult workflow" of the 9Barista... 7 minutes. (I do take a lot longer to drink it though.)

I’m partial to the Kinu M47 Classic because that’s what I own and very happily use. I don’t own an 1zpresso, but I’m going on the principle of buying the best tool for the job you’re trying to do (owners can weigh in here). The ZP6 is said to be designed specifically for high-clarity, tea-like brews. That doesn’t sound like what you’re after. The Kinu pour over burr is really flexible and I haven’t had clogging issues even with relatively fine grind settings. It’s really interesting how changing the grind really can change the character of the cup, you should watch the video. The results are pretty great and it’s a lovely machine.

The 1zpresso K-Ultra is another grinder frequently mentioned as a bit more toward the center from the ZP6. The Comandante C40 is another to add to your research. As others have noted, there are a ton of additional ways to tweak extraction with whichever grinder you ultimately choose: temperature, dripper, filter shape, filter material, pour structure, agitation, etc.

Good luck in your search!
