Short answer
The Barista Express has a 54 mm portafilter and an 18 g dose. Breville calls the built-in tamper 54 mm, which is the nominal size; for an aftermarket tamper or puck screen, buy about 53.3 mm, the size Normcore lists for this machine. Breville's own 54 mm dosing funnel (BEA201) is listed for it. Breville's guide adds three practical points: tamp using 15 kilos of pressure, use the single-wall baskets with fresh beans, and run the cleaning cycle with the cleaning disc when the CLEAN ME light shows.

Do Barista Express accessories fit the Express Impress?
The portafilter and Breville's funnel do: Breville lists spare part SP0027237 and its BEA201 dosing funnel for both. Not every 53.3 mm accessory does, though: Normcore says its 53.3 mm dosing cup is not compatible with the Express Impress.[2][6][9]
