Victoria Arduino Mythos 2

The Victoria Arduino Mythos 2 is one of those grinders that baristas get genuinely excited about. It's the successor to the Mythos One, which became the default grinder in high-end specialty cafes around the world. At roughly $4,000-$5,000, the Mythos 2 is firmly in commercial territory, but a growing number of serious home baristas are buying them too. If you're considering it (or just curious about what makes a $5,000 grinder tick), here's everything I've learned.

I want to be upfront: this grinder is designed for cafes pulling hundreds of shots a day. I'll cover why some home users still choose it, but I'll also be honest about when it doesn't make sense for a home setup.

What Makes the Mythos 2 Different

The original Mythos One introduced a few ideas that changed commercial grinding. The Mythos 2 builds on all of them.

Clima Pro Temperature Control

This is the headline feature. The Mythos 2 has an active heating and cooling system that keeps the burrs and grinding chamber at a stable temperature. Coffee grinding generates heat through friction, and that heat changes how the coffee extracts. In a busy cafe, the grinder gets progressively hotter throughout a rush, and shots start pulling faster as the grounds expand from heat.

The Clima Pro system holds the grinding chamber at a user-set temperature (typically 40-45 degrees Celsius). This means the first shot of the morning and the 200th shot at 2 PM taste the same. For a home user pulling 2-4 shots a day, this feature is less impactful since the grinder never gets hot enough for temperature drift to matter much.

Gravitech Clump Crusher

The Mythos 2 uses a clump-crushing system at the exit chute. Flat burr grinders tend to produce clumps of grounds held together by static electricity. These clumps cause channeling during espresso extraction, which leads to uneven, harsh-tasting shots.

The Gravitech system breaks up clumps before they hit your portafilter. In practice, the grounds come out remarkably fluffy and uniform. I noticed less need for extensive WDT (Weiss Distribution Technique) compared to other flat burr grinders. You still want to distribute and tamp carefully, but the Mythos 2 gives you a better starting point.

Burrs and Grind Quality

The Mythos 2 uses 75mm titanium-coated flat burrs. These are massive compared to home grinders. For reference, most home flat burr grinders use 54-64mm burrs. The larger diameter means more cutting surface, faster grinding, and more uniform particle distribution.

Grind speed is about 2.0-2.5 grams per second for espresso, which means an 18-gram dose takes about 7-9 seconds. That's quick enough for a cafe rush and more than fast enough for home use.

The particle distribution from the 75mm burrs is extremely tight. When I compare shots from the Mythos 2 to shots from my 64mm flat burr home grinder, the Mythos 2 produces noticeably more clarity and sweetness. You can taste individual flavor notes more distinctly. It's the kind of difference that matters to competition baristas and discerning coffee drinkers, though casual espresso lovers might not notice the gap.

Stepless Micrometric Adjustment

The grind adjustment is stepless with a large, easy-to-read micrometric dial on the side. The adjustment is smooth, precise, and you can make extremely small changes. For espresso, where you're dialing in to within fractions of a second on shot time, this level of precision is important.

There's also a digital display that shows grind time, shot count, and other metrics. The interface is touchscreen and easy to use, though it takes some time to learn all the programming options.

Build and Design

Victoria Arduino pays serious attention to aesthetics, and the Mythos 2 is a striking grinder. It has a muscular, angular body with clean lines. It comes in several finishes, including matte black, white, and chrome. It looks like it belongs in a modern specialty cafe, which is exactly the point.

The build quality is exceptional. Full metal construction, heavy (about 35 pounds), and rock-solid on the counter. There's zero vibration during grinding. The portafilter fork holds standard 58mm portafilters securely, and the hands-free grinding means you just place the portafilter, hit the button, and walk away.

Size Considerations for Home Use

The Mythos 2 is big. It's about 25 inches tall, 8 inches wide, and 18 inches deep. It needs a dedicated counter spot and decent headroom. If your kitchen has upper cabinets close to the counter, measure before buying. Many home users end up placing it on a kitchen island or a separate coffee bar station.

It also requires a standard outlet but draws more power than a typical home grinder (about 350 watts). No special electrical requirements, but you'll want a dedicated outlet rather than sharing a power strip.

Is It Worth It for Home Use?

This is the big question, and my honest answer is: for most people, no.

The Mythos 2's biggest advantages (temperature stability, high-volume durability, extreme grind speed) solve problems that home users don't really have. You're not pulling 300 shots a day. Your grinder doesn't heat up enough for Clima Pro to matter. You don't need a grinder rated for decades of commercial use.

What you do get at home is the grind quality from those 75mm burrs and the Gravitech clump crushing. These are real benefits that translate to better-tasting espresso. But you can get 90-95% of that grind quality from a $1,000-$1,500 home grinder like the Eureka Atom 75 or Lagom P64.

The Mythos 2 makes sense for a home user if: you're building a dedicated coffee bar and want a showpiece, you're training for barista competitions, or you found a used one at a significant discount. Otherwise, there are better ways to allocate $5,000 in your coffee setup.

Maintenance for Commercial and Home Users

Despite its complexity, the Mythos 2 is relatively easy to maintain. Nuova Simonelli (Victoria Arduino's parent company) designed it for busy cafes where downtime costs money.

Daily maintenance in a commercial setting means brushing out the chute and dosing area at the end of each day. Weekly, you should remove the burrs and give them a thorough brushing. Monthly, run grinder cleaning tablets through to dissolve oil buildup.

For home use, the schedule is more relaxed. Brush the chute weekly, deep-clean the burrs monthly, and run cleaning tablets every 6-8 weeks. The titanium coating on the burrs resists corrosion and extends their life, so you're looking at many years before needing replacements under home use conditions.

FAQ

How loud is the Victoria Arduino Mythos 2?

It's moderate. The large burrs spin at a relatively low RPM, which keeps noise down compared to smaller, faster-spinning grinders. It's about on par with a Eureka Atom for volume. Not whisper-quiet, but not jarring either.

Can the Mythos 2 grind for filter coffee?

It can be adjusted coarse enough for drip and pour-over, but it's designed and optimized for espresso. The burr geometry, speed, and clump-crushing system are all tuned for fine grinding. If you need a versatile grinder for multiple brew methods, a different machine would serve you better.

How long do the 75mm burrs last?

In a commercial setting (2-4 kg of coffee per day), about 2-3 years. For home use (20-40 grams per day), the burrs would last decades. Replacement burr sets run about $150-$200.

Is there a difference between the Mythos 2 and the Mythos 2 Flat?

The standard Mythos 2 uses a traditional flat burr with a standard profile. Victoria Arduino also offers different burr profiles for different taste characteristics. The standard profile emphasizes sweetness and balance, which works well for most coffee styles. Talk to your dealer about available burr options if you have specific flavor preferences.

The Verdict

The Victoria Arduino Mythos 2 is a world-class commercial grinder that produces exceptional espresso. The temperature control, 75mm burrs, and clump-crushing technology set a high bar. For cafes and competition baristas, it's one of the best options available. For home users, it's spectacular overkill in most scenarios. Put that $5,000 toward a great $1,200 grinder and spend the rest on outstanding coffee beans. You'll enjoy your coffee more that way.
