Know before you buy
The Harold is designed for Breville machines that utilize a 54mm group head. It is compatible with most popular models like the Barista Express, Pro, Touch, and Bambino series, but you should verify your machine's portafilter size before purchasing.
A bottomless portafilter exposes the underside of the basket, allowing you to see the espresso flow in real-time. This visibility is the best way to diagnose channeling or uneven extraction, helping you refine your puck preparation and grind size.
The walnut handle is finished for durability, but it is best to avoid soaking it in water or running it through the dishwasher. Simply wipe it down with a damp cloth after use to keep the wood in good condition.
Yes, the included basket is a standard 54mm size. It works well with most standard 53mm or 54mm tampers and distribution tools, though you may want to check your specific tamper's diameter for the most precise fit.
Because bottomless portafilters offer less resistance than spouted versions, you might find that your extraction flows slightly faster. You may need to adjust your grind to be a touch finer to achieve your desired shot time and flavor profile.
