PROFILERS – Precision Flow Tools for Flatbed Drippers PROFILERS are a set of precision-engineered stainless steel discs designed to modify contact surface, adjust extraction strength, and optimize drawdown flow in flatbed drippers with a 45 mm bed. By varying the open-to-contact surface ratio, each Profiler allows you to fine-tune flow, extraction, and cup clarity without changing your brewer. Each Profiler features a different open surface ratio—from 25% to 85%—letting you experiment and customize sweetness, body, and balance in every cup. Developed with coffee professionals, the Profilers are ideal for experimentation, recipe development, and precise extraction control. Compatibility: Flatbed drippers with a 45 mm diameter bed — including the MANTLE dripper and MK FLAT v1/v2. How to use: Place the Profiler in the dripper, ensuring it sits level Insert a filter and rinse thoroughly to ensure full contact Add coffee and brew as usual Experiment with different Profilers to refine your cup profile Materials & Packaging: Stainless steel AISI 304 with food-grade gold plating.
