IMS Big Bang Precision Filter Basket – 58mm, 18-20g, H23.5 (Double Espresso)

The latest innovation from IMS: holes distributed toward the center to direct the flow of espresso, with more holes and less distance between them near the middle. The pattern is designed specifically for bottomless portafilters, with a flat bottom and ridgeless 70mm border.

The Big Bang's defining characteristic is sweetness — extraction is very uniform, emphasizing sweetness and reducing acidity. Not recommended for light, citric coffees, since it will sweeten and alter their character.

• 585 holes distributed toward the center to direct espresso flow evenly
• Highlights natural sweetness while making extraction more uniform
• Reduces channeling for a cleaner shot
• For 18–20g of coffee, H23.5, 70mm border, fits 58mm portafilters. Made in Italy by IMS
• Fits most E61 group head portafilters, including Gaggia, Astoria, Casadio, Conti, Elektra, Fracino, La Marzocco, Rancilio, Slayer, Synesso, and Victoria Arduino
