Nuova Simonelli Mythos: The Cafe Grinder That Changed the Industry

Walk into any serious specialty coffee shop and there's a good chance you'll spot a Nuova Simonelli Mythos behind the bar. This grinder has dominated the commercial espresso scene for years, and after using one during a two-week stint helping a friend open his cafe, I can see why. The Mythos does things with temperature and consistency that most grinders don't even attempt.

I'll walk you through the different Mythos models, what makes the design unique, how it performs in daily use, and whether any version makes sense outside of a commercial setting.

The Mythos Lineup

Nuova Simonelli has released several versions of the Mythos over the years, and the naming can get confusing. Here's the breakdown.

Mythos One

The original Mythos One launched around 2014 and immediately made waves with its "Clima Pro" technology, a heating system built into the grinding chamber that maintains a consistent temperature. Most grinders get hotter as they work harder, which changes extraction. The Mythos One actively prevents that.

It uses 75mm titanium-coated flat burrs and weighs about 50 pounds. This thing is a tank. The tilt-forward design angles the ground coffee directly into your portafilter, reducing mess and retention.

Mythos Two

The Mythos Two added a touchscreen interface, dose-by-weight technology using a built-in scale, and improved grind speed. It's faster and more accurate than the original, grinding a double dose in roughly 3 seconds with weight accuracy within 0.1 grams.

This is the model you see most often in competition settings and high-end cafes. The World Barista Championship has featured the Mythos Two on its competition stage, which tells you something about where it sits in the industry.

Mythos MYG75

The MYG75 is a more recent addition targeting cafes that want Mythos-level performance with a smaller footprint and lower price. It keeps the 75mm burrs but strips away some of the electronic features. Think of it as the "workhorse" Mythos without the competition bells and whistles.

What Makes the Mythos Special

Temperature Management

I keep coming back to this because it genuinely matters. When you grind coffee, friction creates heat. That heat changes how the coffee extracts. In a busy cafe grinding 100+ doses per hour, the last shot of the morning rush can taste noticeably different from the first.

The Mythos Clima Pro system uses a heating element around the grinding chamber to hold the temperature steady, typically around 40 to 45 degrees Celsius. During slow periods, it warms the chamber to match busy-period temperatures. During rushes, the system dissipates excess heat. The result is remarkably consistent shots from open to close.

I tested this during a Saturday morning rush at my friend's cafe. We pulled shots at 7 AM (quiet), 9 AM (peak), and 11 AM (slowing down). Using the same beans and recipe, all three shots fell within a 1-second window of each other. That's the kind of consistency most cafes can only dream about.

Low Retention

The Mythos retains about 0.5 to 1 gram of coffee, which is very low for a commercial grinder. The angled design uses gravity to push grounds through the chute naturally. Combined with the clump crusher at the exit, what comes out is fluffy, evenly distributed, and ready for tamping with minimal WDT work.

Build and Ergonomics

The tilted design isn't just for looks. It puts the portafilter at a natural angle for baristas, reducing wrist strain during long shifts. The portafilter fork adjusts for both 53mm and 58mm portafilters. And the overall weight keeps the grinder planted firmly on the bar, even when pulling and replacing portafilters quickly.

Performance in Daily Use

Grind quality from the 75mm titanium burrs is excellent. The particle distribution is tight and uniform, producing espresso with clarity and balance. Compared to the Mazzer Super Jolly (another cafe standard), the Mythos produces noticeably fewer fines, which means less bitterness and a cleaner finish in the cup.

The grinder handles light roasts well, which can be a challenge for older commercial grinders. Light roasts are harder and denser, requiring more force to grind evenly. The Mythos's powerful motor and large burrs chew through them without issue.

Noise is moderate for a commercial unit. It's louder than home grinders but quieter than some older Mazzers. The motor produces a low hum rather than a screech.

Should You Buy a Mythos for Home Use?

Here's where I need to be honest with you. The Mythos is a commercial grinder with a commercial price tag. The Mythos One typically runs $2,000 to $3,000 used, and the Mythos Two is $4,000 to $5,000 new. The MYG75 slots in around $2,500.

For home use, it's hard to justify unless you have the budget, counter space, and a dedicated circuit (these grinders draw significant power). The grind quality is phenomenal, but home-focused grinders in the $500 to $1,500 range get you 85 to 90% of the way there.

If you're outfitting a cafe, the Mythos is a top-tier choice. The consistency, speed, and durability make it a smart long-term investment.

FAQ

How long do Mythos burrs last?

Nuova Simonelli rates the 75mm titanium burrs for about 1,300 to 1,500 pounds of coffee. In a busy cafe grinding 20 to 30 pounds daily, that's roughly 2 to 3 months. Home users might never need to replace them. Replacement burr sets cost about $150 to $200.

Is the Mythos One still worth buying in 2026?

Used Mythos One grinders are one of the best deals in commercial espresso right now. As cafes upgrade to the Mythos Two, used Ones hit the market at $1,500 to $2,000. The grind quality is still top-notch, and the Clima Pro system works just as well as it did on day one. The main thing you miss is the dose-by-weight feature of the Two.

Can the Mythos grind for pour-over or drip?

No, and it's not designed to. The Mythos is a dedicated espresso grinder. The burr geometry and adjustment range are optimized for fine grinding. You'd need a separate grinder for filter brewing.

What's the difference between the Mythos and the Victoria Arduino Mythos?

Nuova Simonelli and Victoria Arduino are both owned by the Simonelli Group. Some newer Mythos models are branded as Victoria Arduino rather than Nuova Simonelli, but the engineering and manufacturing are the same. If you see a "Victoria Arduino Mythos MY75," it's the same grinder as the Nuova Simonelli version.

Wrapping Up

The Nuova Simonelli Mythos earned its spot as a cafe staple by solving a real problem: temperature-driven inconsistency during high-volume grinding. The Clima Pro system, low retention, and excellent burr design make it a grinder that delivers the same quality shot after shot, from the first customer to the last. For cafe owners, it's a proven investment. For home users, it's aspirational but probably more grinder than you need. Focus your budget on beans and technique first, and upgrade your grinder when you've outgrown what you have.
