Mythos Clima Pro: The Commercial Grinder That Changed Espresso
The Victoria Arduino Mythos Clima Pro (formerly branded as Nuova Simonelli) is a commercial espresso grinder that you'll find in specialty coffee shops around the world. It's the grinder that introduced active temperature regulation to the grinding world, and it remains one of the most popular choices for busy cafes. If you're researching the Clima Pro, you're probably either outfitting a cafe or considering one for a high-end home setup.
I've used the Mythos Clima Pro in cafe settings and briefly had one on loan for home testing. It's an impressive machine that does specific things better than almost any other grinder, but it's also expensive, large, and designed for a particular workflow. Here's what you should know before committing.
The Clima Pro Temperature System
The headline feature of the Mythos Clima Pro is its Clima Pro technology, a built-in heating and cooling system that maintains a consistent temperature in the grinding chamber. This is the feature that made the grinder famous, and it's worth understanding why it matters.
Why Temperature Matters in Grinding
Grinding coffee generates heat through friction. In a busy cafe grinding hundreds of doses per day, the burrs and grinding chamber can heat up significantly. As the temperature rises, the coffee's flavor profile changes. Hotter grounds extract differently in the espresso machine, leading to inconsistency between the morning rush (when the grinder is cold) and the afternoon rush (when it's been running for hours).
The Clima Pro uses a heating element and a fan system to keep the grinding chamber at a consistent temperature, typically around 40-45 degrees Celsius. When the grinder is cold (first thing in the morning), the heater warms it up. When grinding generates excess heat during peak hours, the fan kicks in to cool things down.
The practical result is more consistent espresso throughout the day. Baristas don't need to adjust grind settings as frequently as the shop gets busy, and shot quality stays more predictable from the first customer to the last.
Does It Matter for Home Use?
Honestly, not much. Home users rarely grind enough volume for heat buildup to become an issue. If you're making 2-4 espressos per day, the grinding chamber barely gets warm. The Clima Pro's temperature system is solving a problem that high-volume commercial environments face, not a problem most home baristas encounter.
Burr Design and Grind Quality
The Clima Pro uses 85mm flat titanium-coated burrs. These are large burrs by any standard, and they produce exceptional particle uniformity for espresso.
Espresso Performance
This is where the Mythos Clima Pro earns its reputation. The 85mm burrs produce an espresso grind with very tight particle distribution. Shots pull evenly with minimal channeling, and you can achieve high extraction percentages (20-22%+) consistently. The flavor clarity is excellent, especially with light and medium roast specialty beans.
The large burrs also mean fast grinding. An 18-gram dose grinds in about 3-4 seconds, which is important for cafe workflow where speed directly impacts customer throughput.
Not For Filter Coffee
The Clima Pro is not designed for filter or pour-over grinding. The burr geometry is optimized for espresso-fine particle sizes, and the grind range doesn't extend coarse enough for most filter methods. This is a single-purpose machine, and that single purpose is espresso.
Build Quality and Size
The Mythos Clima Pro is a commercial machine built for durability. The body is die-cast aluminum and steel, and the grinder weighs about 28 kg (62 lbs). It's engineered to handle hundreds of doses per day for years.
Dimensions
Standing about 24 inches tall and 8 inches wide, the Clima Pro is a substantial piece of equipment. For a cafe, it fits naturally on a counter next to an espresso machine. For a home setup, you need dedicated space and a counter strong enough to support it.
The design includes a built-in tamping station and portafilter fork, which streamlines the cafe workflow. The grounds exit directly into the portafilter, minimizing mess and waste.
The Touchscreen Display
Recent versions of the Clima Pro feature a touchscreen display that shows grind settings, dose times, shot counts, and the current chamber temperature. The interface is intuitive for baristas and includes features like usage tracking and maintenance reminders.
For cafe owners, the shot counter is particularly useful for tracking daily volume and planning burr replacements based on actual usage rather than guesswork.
Grind Adjustment
The Clima Pro uses a micrometric stepless adjustment system. The large adjustment collar provides extremely fine control over grind size. For espresso, where fractions of a setting change shot time by seconds, this precision is important.
The adjustment has zero play or drift, which means once you set it, it stays put. In a cafe environment where multiple baristas use the same grinder, this stability prevents accidental setting changes from bumping or jostling the machine.

Retention and Workflow
The Clima Pro has moderate retention, typically 2-5 grams depending on the grind setting. For a cafe using the same beans all day, this is a non-issue. The retained grounds from the previous dose are the same beans at the same setting, so they blend seamlessly into the next dose.
For a home user who switches between different beans frequently, this retention becomes a problem. You'd waste 2-5 grams of expensive beans every time you switch, plus the first shot after switching won't be pure. This is another reason the Clima Pro is better suited for commercial use than home use.
The Dispensing System
Grounds drop directly into a portafilter held in the built-in fork. The timed dosing is programmable and consistent. Most cafes set a dose time, verify with a scale for the first few shots, and then trust the timer for the rest of the day with occasional spot checks.
Pricing and Ownership Costs
The Clima Pro retails for approximately $3,500-4,000 new, depending on the supplier and any current promotions. Used units appear on the secondary market for $1,500-2,500 depending on condition and age.
Ongoing Costs
- Burr replacement: The 85mm titanium burrs cost about $200-300 for a set and should be replaced after roughly 800-1,200 kg of coffee (every 1-3 years in a busy cafe)
- Maintenance: Annual servicing is recommended for commercial use, typically $150-250
- Electricity: The Clima Pro draws more power than smaller grinders due to the temperature regulation system
For a cafe generating revenue, these costs are minor. For a home user, they add up quickly when compared to the cost of a prosumer grinder that produces comparable results for personal consumption.

Who Should Buy the Mythos Clima Pro
Buy the Clima Pro if:
- You're outfitting a specialty cafe or coffee bar
- You grind 50+ espresso doses per day
- Shot consistency throughout a full service day is a priority
- You have the counter space and budget for a commercial machine
Think twice if:
- You're a home barista (the temperature system and speed are wasted at home volumes)
- You need a grinder that handles both espresso and filter
- Your budget is under $2,000 (excellent prosumer grinders exist for less)
- You switch beans frequently (retention makes this inefficient)
FAQ
Can I use the Mythos Clima Pro at home?
You can, but it's overkill for home use. The temperature regulation system, 85mm burrs, and speed are designed for cafe volumes. For home espresso, a Eureka Atom, Niche Zero, or similar prosumer grinder will produce comparable shot quality at a fraction of the cost and counter space.
How loud is the Clima Pro?
It's a commercial grinder, so it's not quiet. The motor and burrs produce a noticeable grinding noise, and the temperature regulation fan adds a low hum during operation. In a cafe environment, this blends into the ambient noise. In a quiet home kitchen, it's more noticeable.
What's the difference between the Mythos One and the Clima Pro?
The Mythos One is the base model without the active temperature regulation system. The Clima Pro adds the heating element and fan system. For low-volume use, the Mythos One performs similarly. For high-volume cafes where temperature consistency matters, the Clima Pro is the better investment.
How often do the burrs need replacing?
For a busy cafe grinding 5-10 kg per day, the titanium-coated burrs typically last 800-1,200 kg. That translates to roughly 4-8 months of heavy commercial use. For lighter commercial use (2-3 kg/day) or home use, the burrs can last years.
My Take
The Mythos Clima Pro is one of the best commercial espresso grinders available. Its temperature regulation system solves a real problem for busy cafes, and the 85mm flat burrs produce espresso grinds that few grinders can match. But it's firmly a commercial tool. If you run a cafe or high-volume espresso setup, it's an excellent investment. If you're a home barista, your money goes further with a prosumer grinder that matches your actual grinding volume and workflow.
