Shop Moshi conical burr espresso grinders in two primary sizes: the C63 and C83. Both models focus on single-dose grinding and large conical burrs, giving home espresso users an alternative to common compact conical and flat-burr platforms. Open-box C63 units may also appear when available.
Compare the 63mm and 83mm models by burr geometry, motor, adjustment, retention, footprint and price. You can also browse all conical-burr grinders, single-dose grinders, 83mm grinders and open-box deals.

Moshi C63 vs. C83 Conical Burr Grinders
The decision is not simply small versus large. Compare the complete grinder and the espresso workflow you want.
Moshi C63 overview
The Moshi C63 uses a 63mm conical burr platform in a single-dose espresso grinder. It offers a lower price and smaller route into the Moshi design than the C83.
Choose C63 when its footprint, burr geometry and value fit your home bar. Review current dimensions, voltage and included accessories on the product page.
Moshi C83 overview
The Moshi C83 moves to a much larger 83mm conical burr set and corresponding chassis. It suits buyers specifically seeking a large-conical espresso platform.
Larger burrs can influence feed and speed, but they do not automatically produce better flavor. The C83 should be chosen for its particular burr and workflow.
63mm versus 83mm conical burrs
The C63 is easier to justify for value and counter space. The C83 offers a larger cutting platform and potentially faster grinding, but at higher cost and size. Actual output depends on motor, RPM, burr design and beans.
Do not compare the diameter directly with flat-burr grinders as though the numbers describe identical geometry. Conical and flat systems feed and cut differently.
Conical espresso flavor
Large conical burrs are often chosen for texture, body and traditional espresso character. That is a general tendency, not a guarantee. Roast, coffee, water, dose and extraction can change the result.
If you prioritize high flavor separation from light-roast filter coffee, compare the Moshi models against brew-focused flat-burr options before deciding.
Single-dose workflow
Weigh beans before each grind, load them consistently and use the chute-clearing method described for the model. Single dosing supports coffee changes but does not mean literal zero retention.
Measure input and output over several doses and consider exchange. Static and roast level can alter grounds behavior from day to day.
Adjustment and calibration
Espresso requires small, stable changes. Record useful dial positions, adjust one variable at a time and avoid forcing the mechanism when beans are trapped. The marked zero may not equal burr touch.
Never operate with burrs contacting. Follow the model-specific procedure after cleaning or burr access.
Moshi versus compact conical grinders
Compared with a Turin SK40 or hand grinder, C63 and C83 provide much larger burrs, motors and chassis. Compact models cost less and occupy less space; Moshi models target users seeking a large-conical experience.
Choose based on taste and routine rather than assuming large conicals are necessary for home espresso.
Open-box Moshi C63
Open-box C63 listings can offer savings, but condition and included accessories are specific to each unit. Read the listing carefully for cosmetic notes, testing and warranty information.
Open-box inventory is limited and may disappear once the individual unit sells.
Cleaning and maintenance
Unplug before burr access. Brush dry grounds from the chute and chamber and keep liquids away from burrs and electronics. Protect threads and carrier surfaces during reassembly.
If sound, grind time or adjustment changes unexpectedly, inspect cleanliness and assembly before attempting alignment modifications.

Great Roaster Smooth coffee
I bought this roaster to launch my micro roastery. Its amazing, i roast some truly amazing coffee with my kaliedo. I am able to roast all night on it most night i am roasting anywhere from 10-20 batches non stop. The only issue i have had is cooling fans breaking on me i have had to replace 2 cooling fans. But given how much i roast i can not complain, its a work horse and i love it. The best part is the customer service. I will 100 precent be buying my next roaster here because of the customer service. They go above and beyond to help and solve any issues you may have. Lastly i like how easy it is work on and maintain the kalideo. The spare parts are affordable and its easy to replace parts that break. if you need a good entry roaster look no further

Excellent customer service.
The guys at Espresso outlet are extremely knowledgeable, responsive, and helpful. I ordered a Turin machine that arrived damaged. I decided I wanted to go with a different kind of machine entirely. They promptly sent me a return label and refunded me within hours of them receiving the machine. I would definitely consider buying from them in the future.

Package arrived well protected without damage
Package arrived well protected without damage.
I had a thermoblock Breville Bambino before. After ~6yrs using it I could make good cortado but it was inconsistent.
This machine produces quality results every time. The steam is powerful. The extraction is great. Consistent, high temps. We get comments on how nice it looks.
For negatives, the included manual is sparse, especially for maintenance. I’ve found some videos online but many are in Korean so we’re still figuring that out. We drink primarily medium/dark roast. I’ve made light roast with it. It came out ok, but don’t know if I’d suggest it for that.
We were deciding among this, a Quick Mill Pop-Up, or a Profitec Go

Purchased the Moshi C83 Conical Burr Grinder from Espresso Outlet and had a great experience. Joe was very responsive over email and answered all my questions quickly. The grinder shipped fast, was well packaged, and arrived in perfect condition.
The grinder itself has been excellent so far — solid performance and a really good value, especially with the one-year warranty. Highly recommend Espresso Outlet.

Digital Gap adjustment is Amazing
I bought both the Lita and the Milo. I had some concerns about grind retention after watching a few online reviews, but after using the Milo, I haven’t experienced any issues with this.
I really love being able to adjust the burr gap predictably and reliably digitally. It makes dialing in my beans much easier, and once I get a particular bean dialed in, I can save a profile for it and quickly return to those settings later.

Great Machine
Great build quality and just the right amount of adjustability for pressure/flow profiling. I like being able to bind a basic profile to the grouphead button so others in my house can use it without needing to know anything about the advanced menus.

Great Kaleido M10
I started working with Barret on a problem I was having on my son's M6 that we bought from someone else not knowing Expresso Outlet was the sole US Distributor. Barret got him back up and running so I bought a M10 for myself through Expresso Outlet. The unit showed up well boxed and padded. Came with alot of extras. Wired it up and it runs flawlessly. Many Thanks again to Barret for all the email responses we had over the last few months.
