Comandante - X25 Trailmaster Forest

We engineered the COMANDANTE X25 TRAILMASTER® grinder for our weekend adventures in the Bavarian Alps, with the same ‘no compromises’ attitude that serious outdoor enthusiasts approach their equipment choices. We made it lightweight, super robust and functional, with world class grind performance.
It can cope with your biggest adventures and be your reliable coffee companion, wherever you take it!  

Tigershark® Burr

“I’ve always believed that burrs are more than just tools for grinding coffee—they’re precision instruments, capable of so much more than we give them credit for. Most people think about burrs in terms of espresso or filter coffee. But what happens when you push the limits? When you take them into the wild, on expeditions, and need them to do more? That’s how TIGERSHARK® was born.

It all started with light-roasted coffee beans. Their higher density bio-substance and their reduced brittleness change the way they fracture during grinding. They make it hard for traditional burr geometries to produce good grind results, demanding a different approach to cutting and crushing our beans.

But I didn’t stop there. Out in the field, on camping trips and expeditions, I found myself grinding more than just coffee—green spelt grain and rye for porridge and flatbread. After years of testing, tweaking, and rethinking burr mechanics, I landed on something special:

The Double Shark-Tip Blade Structure.

Inspired by the precision and force of a tiger shark’s bite, this unique dual-row blade system cuts cleanly through semi-elastic, high-density materials, from Nordic roasts to sturdy grains. It doesn’t just crush—it slices, fractures, and refines with incredible efficiency.

And because an expedition grinder should be built to handle anything, I crafted TIGERSHARK® from our high-performance stainless steel alloy Nitro Rex®. It’s razor-sharp, incredibly durable, and fully washable, so I can rinse it clean after grinding whatever I need—no worries, no compromises.

I made TIGERSHARK® for adventure. For the ability to grind whatever I need, wherever I go. And after years of using it in the field, I can confidently say—this burr is a little beast. I never leave for an expedition without it.”

– Bernd Braune, Founder

Nitro Rex® – steel like no other

Nitro Rex® is more than stainless steel — it is an achievement of material engineering and craftsmanship. It contains over 17% chromium and precisely balanced amounts of vanadium, molybdenum, and other valuable micro-alloys, giving it outstanding corrosion resistance, hardness, and wear resistance. Its complex remelting process creates a fine, homogeneous structure and a silver-white surface that is not only aesthetically striking but also eliminates the need for coatings. Nitro Rex® stays exactly as it is made: robust, durable, and completely flavor-neutral — allowing coffee to retain its full character.

Nitro Rex® forms the heart of the grinders. It ensures consistent precision and durability, appreciated worldwide — whether grinding ultra-fine espresso or coarse filter coffee. Every COMANDANTE grinder is created for people who refuse to compromise and who share a passion for quality, craftsmanship, and perfect coffee.

QTP® – high-performance techno-polymer

Not all plastics are the same. At Comandante®, advanced materials are chosen with purpose. QTP® is a high-performance techno-polymer — a long-chain polymer matrix reinforced with quartz nanoparticles. It looks and feels like ceramic, yet offers the strength of a super-composite. Designed for durability and precision, it is also food-safe and water-resistant. Quietly cutting-edge, built to perform.

GRIND ADJUSTMENT

Comandante click system gives you full control for any brewing method and locks your preferred grind setting into place, helping you get the very best out of your roasted coffee and repeat the results again and again. This world class grind performance has made Nitro Blade the weapon of choice for true coffee enthusiasts around the globe. Equipped with a convenient Long Grind Dial.

DESIGN

Selecting the best material for an outdoor grinder body is mission critical. After comprehensive research in our laboratories and after conducting extensive field tests, Comandante engineers selected a special reinforced techno-polymer as the material of choice for the new X-Series outdoor products — QTP®. QTP® is a high performance techno-polymer with a substantial amount of quartz reinforcement particles, interwoven into an elastic and strong long-chain polymer matrix. It feels like ceramic and performs like a technical super composite.

The QTP® composite was originally developed for mechanical and equipment engineering. It’s also used in the automotive industry for bearing and gearbox components. QTP® is safe in contact with food and water, and is a trademark of Comandante®.

Stainless steel is the right choice to build a robust and food safe coffee grinder. That is why not only the burr is made of stainless steel, but also the axle, crank and micro ball bearings. Comandante also loves natural wood. The solid oak handles, produced by friends in Germany’s Black Forest, are both wonderfully ergonomic and beautiful to look at thanks to oak’s unique grain structure.

Trailmaster weighs 420 grams (approx. 1/3 lighter than C40 grinder); its height is 20cm and diameter 5,5cm - compact size and robust nature means that whether you’re at home or off on an adventure, the world’s best manual grinder is your loyal companion. The grinder can hold 25-28 grams of coffee at a time. The cap additionaly secures inner parts when travelling. 

Every COMANDANTE X25 TRAILMASTER grinder comes with our food-safe silicone pop-lid, sealing your grinder’s internals from the elements. Load your beans pre-hike, then just pop and grind when you reach the summit, and enjoy your brew with a view!
