What customers say
The IMS Big Bang Basket is widely considered a significant upgrade for 54mm Breville machines, primarily due to vastly improved extraction quality and consistency. Users consistently report achieving more uniform flow, substantially reducing channeling, and unlocking richer espresso flavors compared to the original basket. This precision design allows enthusiasts to reliably dose 18 to 20 grams, enabling greater experimentation. While the initial cost is higher, the consensus is that the professional grade performance gained justifies the investment. Many serious home baristas view this durable accessory as essential for elevating their machine's capabilities, provided they adjust their grinder settings accordingly.
Know before you buy
This basket is designed for Breville machines that use a 54mm portafilter, such as the Barista Express, Pro, Touch, and Bambino series. It is not compatible with Breville's commercial-style 58mm machines like the Oracle or Dual Boiler.
The Big Bang pattern features a unique distribution of holes that concentrates water flow toward the center of the puck. This design helps minimize side channeling, which is a common issue where water bypasses the coffee grounds along the edges of the basket, leading to a more even and balanced extraction.
Yes, because this basket has a 54mm body diameter, you should use a tamper sized between 53mm and 53.4mm for the best fit. A standard 58mm tamper will not fit, and a 53mm tamper will provide the necessary coverage to ensure an even puck density.
The electropolishing process creates a smoother surface that is less prone to coffee oil buildup and residue. This makes the basket significantly easier to clean and provides better chemical resistance against the detergents used in backflushing.
By promoting a more uniform extraction, this basket typically results in a cleaner body and a noticeable softening of acidity. It is an excellent choice if you find your current shots taste sharp or unevenly extracted.
The 18/20g capacity is a general guideline based on the density of medium-roast coffee. If you are using a very light roast, you may fit slightly less, while darker, more porous roasts may allow you to dose on the higher end of that range.
