Can I use a bottomless portafilter on the De'Longhi Dedica?

Yes — a 51mm bottomless portafilter is the most popular upgrade for Dedica owners. It lets you bypass the pressurised baskets and use single-wall baskets, giving you full extraction control and dramatically better shot quality once your grind and technique are dialled in.

What tamper size does the De'Longhi Dedica use?

The Dedica uses a 51mm basket, so you need a 51mm tamper. The stock tamper is plastic and undersized — upgrading to a proper 51mm barista-grade tamper makes an immediate and noticeable difference to consistency.

DeLonghi Dedica

What should I upgrade first? +

Bottomless Portafilter - The single biggest upgrade for Dedica owners. Swapping out the stock pressurised portafilter for a 51mm bottomless lets you use single-wall baskets, see your extraction in real time, and dial in shot quality that the stock setup simply can't deliver.

51mm Tamper - The stock Dedica tamper is plastic and undersized. A proper barista-grade 51mm tamper makes an immediate difference to consistency and is a low-cost, high-impact upgrade.

Distributor - Levels your grounds before tamping, eliminating uneven pucks and reducing channelling. Pairs directly with the bottomless portafilter upgrade.

Puck Screen - Sits on top of your puck before extraction. Improves water distribution and makes the grouphead significantly easier to keep clean.
