ZeroHero Prisma Dripper

The 58-degree angle is engineered to optimize the coffee bed depth, ensuring that water passes through the grounds at a consistent rate. This geometry helps prevent channeling and promotes a more even, balanced extraction compared to steeper or shallower cones.

Yes, because the glass is 3.3mm thick, it is highly recommended to rinse the dripper with hot water before brewing. This pre-heating step ensures the dripper maintains a stable temperature throughout the extraction process, preventing heat loss to the vessel.

The combination of 24 W-ridges and 12 bottom ridges creates air channels between the paper filter and the glass wall. This design prevents the filter from suctioning to the glass, allowing for consistent airflow and a steady drawdown time.

The dripper is designed to be disassembled easily, which makes it compact for packing. While the glass is durable, we recommend wrapping it in a protective cloth or case when traveling to prevent chips or cracks.

The ZeroHero Prisma is designed to work with standard cone-shaped pour-over filters. Ensure you use the appropriate size for a 2-cup capacity to get the best fit against the internal ridges.

The glass body is dishwasher safe, but the walnut base should be hand-washed with mild soap and dried immediately to preserve the wood. The food-grade silicone base can be removed and rinsed under warm water.
