The more we advance in the coffee industry, the more we understand the need for greater precision, especially when it comes to espresso. Pullman recognized the lack of precision when it came to tampers, developing the Big Step tamper that takes advantage of compacting your puck as fully as possible—reducing edge channeling and donut extractions while increasing extraction yields.
However, these benefits were hindered by inconsistent portafilter basket diameters, resulting in limited compaction or even jammed tampers. This led Pullman to tackle the issue of portafilter baskets, leading to the development of the Pullman Filtration Basket.
The ridgeless portafilter basket is hand measured in order to guarantee an internal diameter of 58.70mm, the perfect fit for the Big Step tamper base (58.55mm) as well as tampers ranging from 58-58.4mm. And with consistent hole diameters of 0.3 +/-0.02mm, you have even less of a chance of uneven extraction. This attention to detail gives the Pullman Filtration Basket a leg up over typical OEM baskets.
