A lightweight, virtually unbreakable jar designed around real barista workflows. The Polymer Bean Jar is food-safe and BPA-free, made from Comandante’s high-performance polymer that’s tough enough for daily use yet gentle on your coffee. It’s 100% compatible with C40 Mk3/Mk4 and C60 Baracuda® grinders, so you can pre-dose, store grounds, or swap jars mid-session—then cap it with the included lid. Use it to carry beans, store ground coffee, or even sip a brew directly—the jar’s thick walls insulate heat, keeping coffee warmer while protecting your fingers. The polymer’s surface properties also help lift stray silver skins (chaff) via static, for a tidier workflow and cleaner cup. Typical capacity is about 40 g of whole beans (varies by roast and density). Highlights BPA-free, food-safe, high-performance polymer; Made in Germany. C40 Mk3/Mk4 & C60 compatible; lid included. Flyweight, durable, and travel-ready; ~40 g bean capacity.
