Silicone Bellow for OPUS Grinder

Precision-engineered silicone bellow designed exclusively for the Fellow OPUS coffee grinder. Measures 8.5 cm in height and 7.2 cm in diameter at widest point; weighs 42 g. Made from food-grade, heat-resistant silicone (up to 230°C) with smooth interior surface and flexible yet stable wall structure. Enables full recovery of residual grounds from the OPUS burr chamber and dosing cup. Reduces post-grind retention to under 0.3 g per grind cycle. Compatible only with Fellow OPUS — not suitable for other grinders. The bellow creates an airtight seal between the OPUS burr carrier and dosing cup, preventing grounds from lodging in crevices and ensuring nearly complete transfer of freshly ground coffee. Its tapered geometry matches the OPUS’s internal contours, allowing smooth, controlled dispensing without spillage or static cling. Ideal for daily home espresso preparation where consistency and flavor fidelity matter — especially when using light-roast, single-origin, or delicate specialty coffees. Also supports batch grinding for multiple shots or filter brewing, maintaining uniform extraction across successive doses without cross-contamination or stale residue buildup.
