Victoria Arduino Mythos 1 Grinder: The Full Story
The Mythos 1 is a commercial espresso grinder that redefined what baristas expected from high-volume grinding when it launched. If you're researching it, you're probably either running a cafe, considering one for a home espresso setup, or just curious about why it shows up on nearly every serious espresso bar in the world. I'll give you the complete picture: what it does, why it became the standard, what its limitations are, and what has changed in the years since its release.
This covers the engineering behind the Mythos 1, how it handles dose consistency and temperature, how it compares to its successor and key competitors, and whether it belongs in a home setup.
The Background: Why the Mythos 1 Matters
Victoria Arduino is an Italian company with roots going back to 1905. They're primarily known for espresso machines, but the Mythos 1 grinder, released around 2012, became one of the most influential pieces of equipment in specialty coffee.
Before the Mythos 1, high-volume cafe grinding meant choosing between speed and consistency. Commercial grinders ground fast but heated up quickly, changing the grind as the burrs got hot and expanded. Temperature changes in burrs mean particle sizes shift during service. A grinder that performed perfectly at 7am could be producing different grinds by 10am during a rush.
The Mythos 1 solved this with its Climate Control Technology (Clima Pro), which uses an active cooling system around the burr chamber to maintain burr temperature within a tight range regardless of workload.
What Climate Control Actually Does
The Clima Pro system uses a fan and vent system to actively cool the grinding chamber. This keeps the burr temperature stable whether you're pulling one shot every 10 minutes or one shot every 90 seconds during a rush.
In practical cafe terms, this means your dial-in at the start of service stays accurate through busy periods. A head barista can dial in the grinder before opening and trust that the settings won't drift significantly as volume picks up.
For home use, this is less critical because you're rarely pulling more than a few shots in close succession. But it remains a well-engineered solution that reduces one variable in espresso production.
The Burrs and Grind Quality
The Mythos 1 uses 85mm flat titanium-coated burrs. 85mm is large. Most prosumer home grinders use burrs in the 40-64mm range. Larger burrs mean more grinding surface area, lower RPM needed to process beans quickly, and less heat generated per gram of coffee.
The titanium coating adds hardness and reduces wear. These burrs are designed to hold their edge through millions of doses. In a busy cafe grinding 20kg per week, burr replacement on the Mythos 1 is typically discussed for years rather than months.
What This Produces in the Cup
The Mythos 1 produces what espresso professionals call a bimodal grind distribution, meaning it creates both fine particles (fines) and larger particles (boulders), with relatively fewer particles in the middle size range. Some espresso grinders produce a more unimodal (single peak) distribution.
The bimodal distribution from the Mythos 1 was a deliberate choice that produces a particular espresso character: full-bodied, with strong extraction and good crema. Many baristas appreciate this for milk-based drinks (lattes, cappuccinos) where the body of the espresso needs to hold up against the milk.
For very light roasts and filter-style espresso recipes, some baristas prefer grinders with different distributions. This is one reason the specialty coffee world moved toward a wider range of commercial grinder options in the decade after the Mythos 1's release.
Dosing and Consistency
The Mythos 1 operates on a timed dosing system. You set the dose time, and the grinder runs for that duration each time you activate it. The standard workflow is grinding directly into a portafilter.
Dose consistency in the Mythos 1 is excellent but not perfect. Experienced baristas check dose weight periodically and adjust the timer as beans age (older beans grind faster) or as settings change. This is normal for timed dosing systems and not a flaw specific to the Mythos 1.
The grind retention in the Mythos 1 is higher than most prosumer home grinders, typically in the range of 1-2 grams for the standard version. Stale grounds in the chute can affect the first dose of the day or the first dose after a setting change. Purging a small amount before the first drink of service is standard practice.
The Mythos vs. Mythos 2 (Clima Pro 2)
Victoria Arduino released the Mythos 2 (also called Clima Pro 2) as the successor. The Mythos 2 includes a built-in scale for gravimetric dosing, which eliminates timed dosing variation and adjusts grinding in real time to hit a target weight.
The Mythos 2 also has updated software, a touchscreen interface, and improved cooling.
For new cafe purchases, the Mythos 2 is generally the recommended choice over the original. For existing Mythos 1 owners, the original remains a capable, high-performing grinder that many cafes still run successfully.
The original Mythos 1 is available used at prices well below new Mythos 2 pricing, which is one reason it still comes up in cafe equipment discussions.
How It Compares to Other Commercial Grinders
Mythos 1 vs. Mahlkonig EK43
The EK43 is a different beast: it's primarily a filter/batch grinder that some cafes also use for espresso (particularly for single-origin filter-style shots). The EK43 uses 98mm burrs and produces a different grind character than the Mythos 1.
For traditional espresso in a cafe context, the Mythos 1 is more appropriate. The EK43 is better for filter coffee and atypical espresso recipes.
Mythos 1 vs. Nuova Simonelli Mythos My75
The My75 is a budget-range commercial grinder from the same parent company (Nuova Simonelli owns Victoria Arduino). The My75 uses 75mm burrs and lacks the climate control system. It's a capable grinder for lower-volume settings.
The Mythos 1 outperforms the My75 at high volumes specifically because of the temperature management.
Mythos 1 vs. Mazzer Robur
The Mazzer Robur E and Robur S are the Mythos 1's traditional head-to-head competition in Italian commercial grinders. The Robur uses large conical burrs and has its own strong following. Some baristas prefer the Robur's grind character for milk drinks; others prefer the Mythos 1.
Both are excellent commercial grinders. The preference often comes down to the specific espresso style and machine pairing.
Is the Mythos 1 Right for Home Use?
This is where I'll be direct. The Mythos 1 is a commercial grinder designed for cafe volumes. For home use, it has significant drawbacks:
- It's large and heavy (approximately 12kg). It takes up serious counter space.
- New pricing is in the $2,000-3,000 range, which vastly exceeds what's needed for home espresso.
- The high grind retention means you waste more coffee during single-dose home use.
- The electrical setup (some versions use different voltage) may require adaptation.
Used Mythos 1 units appear on the market as cafes upgrade to the Mythos 2, and prices are lower. Some dedicated home espresso enthusiasts do use them. But for home espresso, there are better-suited options at significantly lower prices that produce excellent shots without the bulk, retention, and commercial-scale considerations.

Maintenance
Burr Cleaning
The Mythos 1's burrs should be cleaned with Urnex Cafiza or a similar espresso grinder cleaner every 10-15kg of coffee ground in a high-volume environment. In cafe settings, this is roughly every two to four weeks.
Remove the upper burr carrier (follows the same quarter-turn removal as most flat burr grinders), brush both burr surfaces thoroughly, and run cleaning tablets after reassembly.
Alignment
The Mythos 1's burrs are factory-aligned. In high-use environments, alignment should be checked periodically. A coffee-grounds-based alignment check (looking for even grind pattern distribution) is a good starting point; professional alignment tools are available for more precise work.
Burr Replacement
The 85mm titanium burrs are designed for long life but do eventually need replacement. Victoria Arduino publishes replacement intervals and sells burrs directly. For most cafes, burr replacement is an annual or biennial service expense.
FAQ
How much does the Mythos 1 cost? New pricing varies by region and distributor, typically $2,000-3,000 USD. Used units are available as cafes upgrade to the Mythos 2, often for $800-1,500 depending on condition.
What's the difference between the Mythos 1 and Mythos 2? The Mythos 2 adds gravimetric dosing (built-in scale), a touchscreen interface, and updated climate control software. The Mythos 1 uses timed dosing. For new purchases, the Mythos 2 is generally recommended.
Is the Mythos 1 good for single dosing at home? Not ideal. Grind retention of 1-2 grams means some waste per dose, which adds up with expensive single-origin beans. Dedicated single-dose grinders at home prices handle this better.
What size burrs does the Mythos 1 use? 85mm flat titanium-coated burrs. This is large by any standard; most prosumer home grinders use 40-64mm burrs.
Summing It Up
The Victoria Arduino Mythos 1 earned its place in specialty coffee history by solving a real problem in high-volume cafe service: temperature-driven grind drift. The climate control system, large titanium burrs, and consistent dosing made it a reliable workhorse for espresso bars that needed predictable performance across long service periods.
For cafe use, especially buying used at current market prices, it remains a strong piece of equipment. For home use, the size, cost, and retention make it a poor fit unless you're specifically pursuing it as a collector's or high-end enthusiast item.
