Nuova Simonelli Inclined Bottomless 21g Portafilter Basket

Bottomless portafilters are specifically designed as a training tool to provide immediate feedback and allow users to identify channeling issues. When channeling occurs, it creates rapid water passages through fractures in the coffee puck, resulting in a thinner, under-extracted espresso. This can be easily detected with a bottomless portafilter, as it often manifests as sudden appearances of blonde streaks in the espresso stream or even pencil lead-sized holes in the puck itself.

The bottomless portafilter featured in this description is designed to fit Nuova Simonelli espresso machines with a 58mm group head, such as the Oscar & Musica models. It is similar in design to the standard portafilters that come with these machines, featuring the same angled "wings," but without the spouts or bottom portion of the holder.

One of the key advantages of this bottomless design is that it makes cleaning the filter baskets much easier. The sturdy plastic handle can also be removed and swapped out if desired, providing users with additional customization options.

By using a bottomless portafilter, baristas and home enthusiasts can quickly identify and address any channeling issues, helping to ensure consistent, well-extracted espresso shots. This tool is an invaluable asset for those looking to refine their espresso-making skills and troubleshoot any potential problems that may arise during the extraction process.

The bottomless portafilter's design, compatibility with Nuova Simonelli machines, and its benefits for cleaning and troubleshooting make it a valuable addition to any espresso enthusiast's toolkit. Its ability to provide immediate feedback and allow for the identification of channeling issues makes it an essential training tool for anyone seeking to master the art of espresso-making.
