Tamping coffee can be a challenge, whether you're a beginner or an experienced barista. Traditional coffee tampers tend to tilt or overdose, potentially ruining even a perfect cup of coffee. Over time, this can also lead to repetitive strain injuries. Upgraded Features from V3: This V4 tamper further enhances the central shaft design, now accepting interchangeable springs (15 lb/25 lb/30 lb) to directly apply pressure to the coffee grounds. Fits 54mm Breville Portafilters: Designed to fit 54mm Breville tapered portafilters (fits Breville/Sage models including Barista Express, Pro, Touch, Bambino Plus, Infuser, and Duo-Temp Pro). Unique Design: The coffee tamper is crafted from a 304 stainless steel base with an anodized aluminum handle. Our coffee tamper is spring-loaded and requires no additional adjustment. It features an ergonomic handle that is comfortable to hold, allowing you to easily press and grind coffee grounds. Consistent Pressure: The amount of pressure you apply is controlled solely by the spring inside the tamper itself. Additionally, it comes with 3 interchangeable springs to suit your preferences. This is the perfect mixer for both the aspiring home barista and the busy coffee shop.
