verybarista IMS Big Bang 58mm Precision Filter Basket – 20-22g (H25.5, 70mm border)

The IMS Big Bang Precision Filter Basket is designed for 58mm portafilters and built to direct espresso flow toward the center. Available in four heights to match different coffee styles, it supports 20-22 grams and works with tampers around 58-58.5mm. Crafted in Italy by IMS, this ridgeless basket features a flat bottom for a clean, predictable extraction in a variety of setups.

Design and performance highlights

• Center-weighted hole pattern directs the espresso flow toward the center for balanced extraction.
• BIG BANG filters emphasize the sweetness of coffee and can influence perceived balance.
• Extraction tends to be uniform, helping to minimize channeling and variability between shots.
• Designed for 20-22 grams of coffee, H25.5 height, 70mm border, compatible with 58mm portafilters. Made in Italy by IMS.
• Ridgeless rim and flat bottom support a clean, predictable bed across brands and machines.

Usage notes and compatibility

• Fits most 58mm portafilters across a wide range of brands, including popular group-head systems.
• Specifically useful for bottomless portafilters to observe and optimize flow behavior.
• Compatible with 58-58.5mm tampers, helping maintain an even seal and distribution.
• We don\'t recommend using the Big Bang filters with very light citric coffees, as the design can emphasize sweetness and alter flavor balance.

Whether you seek consistent results, a sweeter cup, or a more forgiving extraction across grind and roast variations, the IMS Big Bang basket offers a precise, Italian-made option to explore. As with any espresso tool, outcomes can vary with grinder, roast, and technique, so view this as a possibility to experiment rather than a guaranteed result.
