The TIMEMORE Crystal Eye B75 is a flat-bottom pour-over coffee dripper made from clear PCTG, with 75-degree geometry and 20 interior flow channels. It is designed for smaller pour-over recipes using up to about 15g of coffee. The flat bed gives you a different brewing layout from a cone dripper, while the internal grooves create paths for brewed coffee to move toward the base. Key details Brewer type: Flat-bottom pour-over dripper Geometry: 75-degree design Flow system: 20 inward interior channels Material: PCTG Suggested dose: Up to about 15g of coffee Color options: Clear or amber black What does the B75 design do? The flat bottom keeps the coffee in a relatively level bed during brewing. Twenty grooves inside the brewer are designed to maintain space between the paper filter and dripper so coffee can draw down through the base. Your final cup will still depend on the coffee, grind, dose, water, pouring pattern, and total brew time. Is this a one-cup dripper? The supplied information describes it as suitable for one-cup recipes using up to about 15g of coffee. Finished drink volume will depend on the coffee-to-water ratio in your recipe. What is included? This listing is for one TIMEMORE Crystal Eye B75 dripper in the selected color. Paper filters, a coffee server or mug, kettle, grinder, scale, and coffee are not listed as included.
