New, Unused MHW-3BOMBER DH Filter Basket 18g The following is extracted from the manufacturer's website: Unleashing the true potential of medium-dark and dark roast coffee The MHW-3BOMBER DH filter basket is precisely crafted to bring out the best flavors of medium-dark and dark roast coffee beans. Through extensive research and prototyping, we have designed a filter basket that optimizes extraction for these rich roasts, enhancing sweetness and texture while minimizing bitterness. Optimal for medium-dark / dark roasts: Specially designed to enhance the flavors of medium-dark and dark roast coffee beans, the DH filter basket maximizes sweetness and texture while suppressing bitterness, delivering a smoother, more balanced cup. Three different pore sizes: Featuring three different hole sizes, this basket adjusts flow rate and pressure distribution, optimizing the extraction process for uniform and controlled extraction, resulting in better extraction and flavor. Uniform cross arrangement: Carefully arranged cross-patterned holes maintain constant pressure and flow, reducing channeling effects and allowing for even extraction of coffee oils and flavor components. This enhances the overall coffee experience. Straight-cylinder flat bottom: The grooveless, straight, and flat bottom design evenly distributes moisture throughout the coffee grounds, providing consistent extraction. It also improves compatibility with tampers and measuring tools, enabling a more efficient and easier extraction process.
