What size accessories do I need for the Breville Barista Express and Barista Pro?

Both machines use a 54mm, 3-ear grouphead. You need 54mm portafilters, puck screens, dosing rings and dosing cups. For tampers, 53mm is recommended as it gives a clean fit without scraping the basket walls.

What is the best first upgrade for a Breville Barista Express or Pro?

A 54mm bottomless portafilter is the most impactful first upgrade. It shows your extraction in real time and helps you dial in technique fast. Pair it with a proper 53mm tamper for the biggest improvement to shot quality.

Does the Breville Barista Express take the same accessories as the Barista Pro?

Yes — both machines use the same 54mm, 3-ear grouphead design so all accessories are interchangeable between the Barista Express (BES870) and Barista Pro (BES878).

Will aftermarket accessories void my Breville warranty?

Using correctly sized aftermarket accessories should not void your Breville warranty for unrelated issues. Under Australian Consumer Law, your consumer guarantees remain intact.

What should I upgrade first? +

Bottomless Portafilter — The single most impactful upgrade. See your extraction in real time and dial in your technique fast.

Tamper — The stock Breville tamper is plastic and undersized. A proper 53mm barista-grade tamper makes an immediate difference to consistency.

Puck Screen — Sits on top of your puck before locking in. Distributes water evenly, reduces channelling, keeps your grouphead cleaner.

Distributor or 2-in-1 — Levels your grounds before tamping for more consistent shots. Our 2-in-1 tamper & distributor combo is one of our most popular Breville upgrades.
