O20 Manual Coffee Grinder: Precision and ease in one package.

There was a time when the idea of a manual coffee grinder that could do it all was just a dream—until we met the O20 by Vevok Chef.

From the finest grind ready for espresso to the coarsest perfection for cold brew, it does it all in one single coffee grinder.

Among the features that make the O20 stand out, a few deserve special mention right from the start:

External Coarseness Adjustment

Switching up your grind size has never been easier. With the O20’s external adjustment, you can go from espresso fine to French press coarse with a simple twist—no need to disassemble anything. Plus, check out the inside of the lid!

Full-Metal Body and Mechanism

The O20’s all-metal build gives it a solid, durable feel that you want in a grinder. It’s designed to handle daily use without breaking a sweat, and it just feels great in your hands.

Big Hopper and Container Capacity

The O20’s bigger hopper means fewer refills. You can grind enough for a couple of cups in one go, which is great when you’re making coffee for yourself—or a friend or two.

Effortless Grind Control - The External Adjustment 

One of the standout features of the O20 is its external grind adjustment mechanism. Unlike many grinders that require you to take them apart (even if just to take away the bean jar) to change grind size, the O20 lets you switch between settings with just a simple twist. No disassembly needed—just quick, on-the-fly adjustments.

And here’s where it gets even better: the O20 has 20 different levels of adjustment (get it? O20, 20 levels), giving you a wide range of options for dialing in the perfect grind size. Whether you need a fine grind for espresso or a coarser one for French press, you’ll find the right setting with ease. Plus, there’s a visual guide right on the inside of the lid, so you don’t have to memorize what each number corresponds to. It’s a small detail, but it makes a big difference when you’re experimenting with different brew methods.

Burr Design for Consistency: The Heart of the O20

At the center of the O20 is a set of titanium-coated burrs—and this coating isn’t just for show. Titanium makes the burrs significantly more durable than standard stainless steel, meaning they last longer and stay sharper over time. This increased durability is especially important for a manual grinder because the sharper the burrs, the more consistently they grind your beans.

By investing in titanium-coated burrs, the O20 isn’t just built for today’s coffee—it’s built to last. You'll get a longer lifespan and less wear-and-tear, ensuring smooth, reliable grinding for years without the burrs dulling.

Why Consistency is Key in a Manual Grinder

Consistency in grind size is the single most important feature in a manual grinder, and the O20 excels in this area. The titanium-coated burrs are engineered to create uniform particles, which is essential for even flavor extraction. When your grind size is inconsistent, some coffee particles will extract faster than others, leading to a cup that’s either over-extracted (bitter) or under-extracted (sour). With the O20, you avoid this problem entirely.

 

Whether you’re brewing a fine grind for espresso or a coarse grind for French press, the O20’s consistency ensures that your coffee will be perfectly balanced, bringing out the best flavors in every brew.

Built to Last: Durability in All-Metal Design

The O20 Manual Coffee Grinder is constructed entirely from metal, with no plastic components whatsoever. This full-metal build not only gives it a premium, solid feel but also ensures durability for long-term use. The grinder’s body and internal parts are made from high-quality stainless steel and aluminum, providing strength and reliability with every grind.

Because of its tough construction, the O20 is safe to travel with—it can handle the bumps and jostles of being packed in a bag without worrying about cracks or damage. Despite its compact size, it boasts a large hopper and container capacity, allowing you to grind enough coffee for multiple cups at once, making it ideal for both at-home brewing and coffee lovers on the go.

Easy Maintenance for Daily Use

The O20 Manual Coffee Grinder is designed with convenience in mind, especially when it comes to maintenance. Thanks to its external adjustment system, cleaning the grinder is hassle-free. You don’t need to take apart complicated components just to clean it making regular upkeep easy.

With the included cleaning brush and air blower, you can effortlessly remove coffee residue from the burrs and inner parts. Regular cleaning not only keeps your grinder looking fresh but also ensures it performs like new every time you use it. This easy maintenance routine makes the O20 perfect for daily use without the worry of buildup or dull performance.
