Testing

TDS & Extraction Yield

The finer billet portafilter was third-party tested for TDS and Extraction Yield by Robert McKeon- @espressofun on Instagram. Each dot on the graph represents a “paired shot”, meaning shots pulled back-to-back, with all variables controlled as tightly as possible. 

The performance of an industry-leading billet espresso basket is plotted on the X-axis, and the performance of the finer billet portafilter is plotted on the Y-axis. This means any dot falling above the black line represents a shot where the finer portafilter outperformed the competitor, and any dot below the black line means the competitor performed better. 

With the majority of points falling above the black line, this test demonstrates that the finer portafilter handily outperforms one of the best billet baskets on the market!

Thermal Stability

The copious mass and homogenous thickness of the finer billet portafilter mean it retains heat significantly longer and cools more evenly than a traditional two-piece portafilter. The benefit? More consistent shots, even when your portafilter remains out of the grouphead during periods of grinding, puck prep, and life's distractions! Check out the thermal imagery below, comparing the finer billet portafilter to a traditional two-piece portafilter, both just after removal from the grouphead, then after 10 mins resting at room temp. 

An end to "raining" shots!

A common issue with competitors' billet portafilters, billet baskets, and even some traditional two-piece portafilters, are shots that "rain" from the bottom of the basket, rather than coalescing into a single, clean stream. This can result in a big mess, especially when pulling shots into a small espresso cup! The patent-pending convex surface of the finer billet portafilter ensures that your shot coalesces into a perfect, single stream.
