Know before you buy
Yes, this basket is designed to fit standard 58mm portafilters. However, please ensure your portafilter has enough internal depth to accommodate the 24mm height of this basket.
The ridgeless design allows the coffee puck to slide out easily after extraction, making cleanup faster and more efficient. It also ensures a consistent seal against the group head gasket without the interference of a ridge.
Yes, this basket is optimized for doses between 16 and 18 grams. You may need to adjust your grind size slightly depending on whether you are dosing at the lower or higher end of that range to achieve your desired extraction time.
Electropolishing removes microscopic surface imperfections from the stainless steel. This creates a smoother, more hygienic surface that resists coffee oil buildup and makes the basket easier to clean.
No, this basket is not dishwasher safe. We recommend rinsing it with hot water after each use and performing a deeper clean with a dedicated espresso machine detergent periodically to maintain the precision of the 715 holes.
The flat-bottom design promotes a more uniform coffee bed, which helps prevent channeling and ensures water passes through the grounds evenly. This results in a more balanced and consistent extraction compared to traditional tapered baskets.
