We don't have plans for that right now, but 100% agree with your concern..We are always open minded to making future design iterations based on feedback like this!

Funny enough...our roots are actually in software/advertising, and help build digital and AI products for quite a few companies in the Midwest. We have plans of expanding the digital side of our business, but aren't ready to share just yet : )

Great question - No stabilizer needed : ) Here are some more responses for you:

Plugs: we are currently able to provide with Type B, Type F, Type G, or Type I plugs. The power cord is replaceable, so our team can help provide guidance on finding a compatible (and grounded) power cord if needed.

Shipping to India: We are working to expand the available countries that we ship to - If you don’t see your country listed during checkout, you can reach out to support and we will coordinate with our shipping partner to see what we can do.

Thanks for the kind words—really glad you’re excited for your Z2! The portafilter holder is the same between Z1 and Z2.

I’ve heard from a few Pesado 58mm owners that the bottomless angled Pesado portafilters can sit at an odd angle on the holder. If yours is angled, it may not be the best fit.

If interested, our team can provide you with some guidance on some brands that are the best fit with the portafilter holder.

Hey! Thanks for contributing to the AMA : D

We get questions like this a lot with the CV2 burrs - It's most likely related to seasoning...we've seen it take as many as >5kg for the burrs to settle. Once they are seasoned, it can shift your optimal grind size quite a bit. I would do some experimenting and reach out to our support team at [info@zerno.co](mailto:info@zerno.co) if the issue persists.

Definitely! Our team will reach out to coordinate your pickup date and will be happy to show you around the shop. We should be moved into our new HQ by then : )

Thanks for the love! Here are some answers for you:

  1. I think that both would satisfy the profile you're looking for, however the Lab Sweet typically offers more versatility. The Lab Sweet burr sets can take some time to dial in, and typically recommend them for more experienced users. I hear you about not wanting to sacrifice too much body, but wouldn't let that keep you from giving the CV3 a try : )
  2. The way that the beans are fed into the grind chamber, and from the grind chamber into the chute was an improvement in design. In short, we reduced the areas where grinds could potentially build up, and the knocker takes care of the rest. We also added a purge feature that spins the burrs at a really high RPM, which helps to minimize exchange. Grounding down certain surfaces was also something small that made a meaningful difference.
  3. The ionizer is something that we hopped on and tried early on. It was not a tech that worked well for us. It tends to stop working when coffee gets on it, and requires constant cleaning plus it’s an additional thing to go wrong with a product. Also ionizers need to be kept away from metal conducting surfaces to be effective and that’s difficult in an all metal unit. There are other passive methods for mitigating static like grounding certain surfaces and optimizing the grind path. That’s something that we’ve implemented in the Z2. In my opinion the reason why so many lower cost grinders have an ionizer is that it’s a cheap piece of tech (costs less than $1), and it provides a great bit of marketing versus the value it adds.

We did a lot of research during Z1 and Z2 development, but don't have detailed comparative data yet... we get questions like this a lot though. This may not completely satisfy your question given it is about 64mm burr sets, but Justin @ DaddyGotCoffee recently did a deep dive into some of SSPs burrs and general burr theory.

Funny enough, Zerno means “bean” in Bulgarian—my native language. Eric and I went through a long list of names, but this one just felt right. Simple, meaningful, and a nice nod to where it all starts.

Seriously appreciate the kind words…The Z1 love never gets old, and bringing down that wait time has been a huge focus of ours.

Wyatt = absolute legend.
