Suprima Instrument SD-1 Coffee Dripper

Designed by 2x Indonesian Brewers Cup Champion Hiro Lesmana

The SD-1 Coffee Dripper is engineered around three core principles: consistency, repeatability, and durability. By addressing common challenges found in conventional drippers—such as unstable flow, inconsistent extractions, and material wear—the SD-1 offers a more reliable and precisely controlled manual brewing experience.

At its core, the SD-1 utilizes a hybrid brewing method: immersion and percolation. This simultaneous integration of two traditionally separate extraction processes creates a unique flavor profile, balancing body and clarity while providing enhanced control over brewing variables.

The defining feature of the SD-1 is its controlled channeling design, which regulates water flow through the coffee bed with exceptional precision. Unlike conventional drippers that often allow uneven channel formation, the SD-1’s geometry actively directs water to improve saturation, optimize extraction yield, and minimize the risk of under- or over-extraction.

The SD-1 Design incorporates

• Negative channel geometry along the interior walls, promoting even water dispersion.

• A semi-immersion structure that holds water momentarily before percolation begins, enhancing bloom and ensuring even extraction.

• An external indentation at the base to ensure a secure fit on most standard servers and carafes, improving stability during brewing.

Filter Compatibility

The SD-1 is compatible with standard creped conical filters in Hario 02, Cone Medium, and ORIGAMI 4-cup sizes.

While the SD-1 is a precision brewing tool, its design prioritizes user experience. The form factor, materials, and geometry are optimized not only for extraction performance but also for durability and ease of use. Manufactured in Indonesia using shatterproof polypropylene (PP), the dripper is both durable and highly thermo-stable. Each design decision reflects a commitment to delivering consistent, professional-level results.
