The BIT BoB Filter Basket range is designed by Sauro Dall’Aglio with IMS to deliver richer, sweeter extractions. Using a curved Pozzetto shape, each basket guides water toward the centre of the puck, reducing edge channelling and enhancing body, clarity and balance in the cup. Available in multiple sizes, the 16g and 18g baskets suit those wanting fuller flavour without excess volume, while the 21g produces a bolder, more intense shot. A 54mm 18g option is also available for Breville and Solis machines, giving access to BoB performance beyond standard 58mm setups. Crafted in Italy from premium stainless steel, every BoB basket shares the same goal: smoother extractions with greater sweetness and complexity. BIT BoB Filter Basket Features Curved Pozzetto Shape – The curved design promotes water flow from edge to centre, helping reduce channelling at the rim. Four Variants For Dosing Range – 16g, 18g and 21g in 58mm, plus an 18g in 54mm to suit different machines and dose preferences. Italian Stainless Steel Build – Precision engineered from food-grade steel for consistent heat retention, durability, and clean extraction.
