Ice Eye B75 Flat-Bottom Dripper Review: How a Large-Hole Design Unlocks Coffee's High Sweetness and Cleanliness

Front Street Coffee has previously introduced the concave-designed conical Ice Pupil dripper, and today we bring its younger sibling—the Ice Pupil B75. This flat-bottom dripper, co-designed by Li Jinlong and Timemore in 2022, gets its name from the Basket and its 75° angle. It features a 5cm extra-large drainage hole and a thick-walled heat-retaining structure, bringing the coffee bed closer to a cylindrical shape, allowing for smooth and even drainage. Front Street conducted both hot and iced brewing tests using Ethiopian 74158 Santa Vini and Emerald Green Label Geisha: during hot brewing, the B75 maintained a stable flow rate throughout, completing extraction in 2 minutes and 9 seconds, with prominent notes of dried mango, strawberry, and black tea, and an extremely strong sweetness; during iced brewing, it presented a balanced juice-like quality of honey, cream, and mandarin orange. The B75 is also very friendly to beginners who are not skilled at flow control, making it a powerful tool for amplifying the strengths of sweet beans. [more…]
