Description
Every dose, exactly the same weight
Cafés and home brewers running a Comandante grinder know the frustration — a jar that weighs slightly different from the last throws off every scale reading before the coffee even hits the burrs. The Comandante bean jar fixes that at the source.
Machined from a high-performance, food-safe polymer, this jar and lid combination is built in Germany to the strictest food-safety standards. It replaces the stock C40 bean jar without any modification, and its vertical, super-smooth sidewalls keep ground coffee moving rather than clinging to the sides.
Precision by design
- Uniform weight across every jar — pre-weigh doses at home, at work, or at competitions.
- Static charge lifts unwanted chaff off ground coffee for a cleaner cup.
- Smooth vertical sidewalls minimise retention when dosing into a brewer or portafilter.
- Food-safe, BPA-free, high-performance polymer, made in Germany.
