Know before you buy
The convex shape increases puck resistance, which forces you to use a coarser grind than you would with a standard flat-bottom basket. This design promotes a more even extraction and is particularly effective for blooming shot techniques.
The Sworksdesign Convex Billet Basket is designed for non-pressurized portafilters. You must verify your machine's required lip outer diameter, hole coverage diameter, and overall height from the available specifications to ensure a proper fit.
This basket is versatile enough to handle dose weights ranging from 8g to 20g. You should choose the specific height variant that best accommodates your preferred dose to ensure optimal headspace.
Yes, this basket is not dishwasher safe. To maintain the precision-engineered holes and the integrity of the stainless steel, you should hand wash it gently after each use.
Because the convex geometry creates higher resistance during the brewing process, a finer grind can lead to over-extraction or choking the machine. A coarser grind allows water to flow more evenly through the puck, balancing the increased resistance.
