Exclusively crafted and modified for Verybarista by IMS, this filter basket features a unique convex bottom, designed to concentrate water flow towards the center for a more efficient extraction and exceptional performance for home baristas. The cylindrical design with a convex base optimizes the collection of coffee grounds, promoting even extraction and consistent puck drying. This results in better flavor and a smoother espresso. For the best performance, it’s recommended to use it with a bottomless portafilter. Ideal for pairing with premium grinders and specialty coffee beans. h25 and h27 baskets feature an "E" pattern hole design, perfect for all coffee roasts. h30 basket has an "M" pattern with more holes, making it great for light to medium roasts. For h27 and h30 to fit in stock portafilters, the plastic bottom part of the portafilter must be removed.
