The open window lets you watch the stream form and connect flow patterns to flavor.
Build
A food-grade, one-piece 304 stainless steel body with a titanium-black electroplated finish and a rosewood handle.

The 58 mm standard accepts most powder baskets on the market. Choose an ordinary basket or a precision powder basket with more than 1700 micro-perforations.
Fit
Versions are available for E61 group heads (ECM, Rocket, Flair 58, Lelit, Profitec and others), La Marzocco and three-ear Casabrew machines.
What does a bottomless portafilter do? It removes the spouts so you can watch the espresso flow from the basket and spot channeling. This 58 mm version comes in E61, La Marzocco and Casabrew fits.
Selected for baristas who want to read their shots, not guess at them.
