Upgrade your Comandante® C40 (Mk3 and Mk4) with a smarter, stronger, and more versatile bean jar. The Polymer Bean Jar is an essential accessory for any coffee enthusiast, whether at home, traveling, or in a competition.
Built for travel – and to last This is the perfect travel solution. The jar is made from an advanced, high-performance polymer that makes it extremely lightweight and virtually unbreakable. Use it to transport beans, store ground coffee, or even as a robust coffee cup on the go. Its thick walls provide excellent insulation, keeping your coffee warm longer and protecting your fingers.
A revolution for your workflow The new design is about more than just durability; it enhances your workflow:
Perfect pre-dosing: All Polymer Bean Jars have an identical (uniform) weight. This is ideal for pre-weighing multiple precise doses of coffee, whether you're preparing for a busy morning, at work, or competing in a barista competition.
Cleaner coffee: The material helps remove unwanted silver skin (chaff) from ground coffee through static attraction, resulting in a cleaner taste in your cup.
Zero waste: The super-smooth and perfectly vertical inner walls ensure minimal "retention" – all that precious coffee slides easily out and into your filter or portafilter.
German precision and safety The jar is manufactured in Germany from BPA-free polymers that meet the strictest food safety standards. It is gentle on your precious coffee beans but engineered to withstand years of intensive use.
Available in a range of classic and new colors – choose your style! See more colors here.
