The metal version of OREA’s compact O1, released five years after the original V1. It is a low-bypass flat bottom dripper built from a single piece of double-walled SUS304 stainless steel, with the classic OPEN bottom that OREA’s brewers are known for. The interior is electropolished so there is no metallic taste in the cup, and the exterior is hand-polished to a finish between brushed and mirror. RAW is entirely uncoated, which means it goes in the dishwasher and will not wear or chip over time.
