Victoria Arduino Mythos Commercial Espresso Grinder

The Victoria Arduino Mythos is the benchmark commercial espresso grinder in specialty coffee — trusted by World Barista Championship competitors, adopted by leading coffee shops worldwide, and engineered for the demands of high-volume professional service. Since its debut in 2013, the Mythos has defined what precision grinding looks like in a working café environment, combining Clima Pro temperature control, titanium-coated long-life burrs, Clump Crusher technology, and an intuitive interface into a grinder that delivers consistent, repeatable espresso extraction from opening to close.

Available in six configurations — covering 65mm, 75mm, and 85mm burr options, timed dosing and grind-by-weight gravimetric models — the Mythos range provides the right tool for every café workflow and volume requirement.

Why the Victoria Arduino Mythos is the Industry Standard

The Mythos isn't just popular — it is the grinder that specialty coffee professionals reach for when consistency, reliability, and precision are non-negotiable. Its dominance at the World Barista Championship from 2022–2025 as the official grinder is a direct reflection of its performance under the most scrutinised conditions in coffee.

• Clima Pro temperature control (adjustable 30°C–60°C) — actively monitors and maintains grinding temperature throughout service, preventing heat-induced grind variation that affects extraction and flavour consistency
• Titanium-coated long-life burrs — reduce heat transfer during grinding, extend burr life significantly, and preserve coffee flavour during high-volume service
• Micrometric grind adjustment — fine-tune grind size with precision via the interface, with burr distance controllable to exacting tolerances
• Clump Crusher technology — breaks up clumps in the ground coffee as it exits the grinder, improving distribution into the portafilter and shot consistency
• Dual fan cooling system — integrated fans maintain stable internal temperature throughout the grinding day, protecting both the burrs and the coffee
• Touchscreen interface (MY75, MY85, MYG75, MYG85) — full-colour display provides access to grind settings, dosing programmes, diagnostics, and temperature monitoring
• Gravimetric dosing (MYG75, MYG85) — grind-by-weight technology doses coffee by mass rather than time, eliminating dose variation caused by bean density changes
• Programmable multi-dose settings — save multiple dose programmes for different recipes, coffees, or baristas
• Stop and Go function — allows grinding to be paused and resumed mid-dose for workflow flexibility
• 1.5kg bean hopper — generous capacity for busy café service
• Grinding speed (MY75): 2.7–3.5g/sec | (MY85): 4.0–4.5g/sec
• Power: 600W | Weight: 23.8kg (MY75/MYG75), slightly heavier for 85mm models
• WBC Official Grinder 2022–2025 — validated at the highest level of competitive coffee

Mythos Model Guide — Which Version is Right for Your Café?

The Mythos range offers six distinct configurations to match different café volumes, workflows, and dosing preferences:

MYONE / MY65 — ideal for smaller independent cafés requiring reliable precision without the full touchscreen interface. The 65mm burrs on the MY65 suit lower to medium volume environments.

MY75 / MY85 — the core Mythos models for specialty cafés. The MY75 suits most independent and specialty coffee bars; the MY85's larger burrs deliver faster throughput for higher-volume environments.

MYG75 / MYG85 — gravimetric dosing models that weigh each dose during grinding, compensating automatically for changes in bean density. Recommended for cafés that prioritise recipe accuracy and minimal coffee waste across the full day.

Why Temperature Control is Non-Negotiable in Commercial Grinding

As a commercial grinder runs through service, burr temperature rises. Even small increases in grinding temperature affect particle size distribution and alter how coffee extracts — leading to shot-to-shot inconsistency that is difficult to identify and correct in a busy café environment.

Clima Pro solves this by actively regulating grinding temperature throughout the entire service period, keeping conditions stable whether it's the first shot of the morning or the hundredth of the afternoon. For specialty coffee shops where recipe consistency is a core part of the customer experience, this is not a luxury — it is a fundamental requirement.

Frequently Asked Questions

What is the Victoria Arduino Mythos used for? The Mythos is a professional commercial espresso grinder designed for specialty coffee cafés, high-volume coffee bars, and coffee roasteries with retail operations. It is engineered for consistent, precise espresso grinding throughout full-day service.

What is Clima Pro technology? Clima Pro is Victoria Arduino's proprietary temperature management system, integrated into the Mythos range. It monitors the internal grinding temperature and maintains it within a set range (adjustable between 30°C and 60°C), preventing the grind size variation that occurs when burrs heat up during heavy use.

What is the difference between the timed and gravimetric Mythos models? Timed models (MY75, MY85, MYONE) dose coffee by time — a set number of seconds per shot. Gravimetric models (MYG75, MYG85) dose by weight, measuring the mass of coffee exiting the grinder in real time and stopping when the target dose is reached. Gravimetric dosing compensates for changes in bean density throughout the day, producing more consistent doses and reducing coffee waste.

Which Mythos model is best for a busy specialty café? For most specialty cafés, the MY75 provides the ideal balance of precision, throughput, and workflow features. For higher-volume environments — flagship sites, large coffee bars, or multiple-grinder setups — the MY85's larger 85mm burrs deliver faster grinding speeds of 4.0–4.5g/sec. The MYG75 or MYG85 are recommended when dosing accuracy and recipe consistency are the top priorities.

Is the Victoria Arduino Mythos the WBC official grinder? Yes. The Mythos was selected as the official coffee grinder of the World Barista Championship from 2022 to 2025, recognising its performance, consistency, and reliability under the most demanding competitive conditions in specialty coffee.

Can the Mythos save multiple dose settings? Yes. The touchscreen models (MY75, MY85, MYG75, MYG85) support programmable multi-dose settings, allowing baristas to save different dose programmes for different coffees, recipes, or workflows.
