Saint Anthony Industries The Harold Portafilter

The Harold is specifically designed for machines with an E61 grouphead. As long as your machine uses a standard 58mm E61 group, this portafilter will be compatible.

A bottomless design exposes the underside of the basket, allowing you to observe the extraction in real-time. This visibility helps you identify channeling or uneven extraction, making it an essential tool for refining your technique.

The included basket is designed for a 22-gram dose, which is on the larger side for a double shot. You can adjust your dose slightly, but for the best results, you should aim to keep the coffee bed depth consistent with the basket's intended capacity.

To maintain the wood's finish, avoid submerging the portafilter in water or running it through a dishwasher. Simply wipe the handle clean with a damp cloth after use and occasionally apply a food-safe wood oil to keep the walnut hydrated and protected.

Yes, it can. Because there are no spouts to direct the flow, any imperfections in your puck preparation may cause espresso to spray or drip outside of your cup. It is a great way to improve your distribution and tamping skills, but be prepared for a slightly steeper learning curve.
