FAQ

Coffee & Bakeware — FAQ

Why is a backflush disc necessary?

It allows you to clean the internal dispersion screen and solenoid valve. This ensures your coffee tastes fresh every time.

Does the tamper pressure really matter?

Yes, consistent pressure prevents channeling in the coffee bed. It leads to a more balanced and sweet espresso shot.

How often should I replace group head screws?

Replace them if you notice stripping or signs of corrosion. Keeping these parts fresh protects your machine's threads.

Are automatic tampers worth the cost?

They are ideal for high-volume settings where wrist fatigue is a concern. They provide perfectly level tamping every single time.

Can I use these tools with a La Marzocco?

Many professional-grade tools are designed specifically for the 58mm standard. Always confirm compatibility with your specific model.

Is a super-automatic machine easy to maintain?

They often feature self-cleaning cycles that simplify maintenance. However, regular manual deep-cleaning is still recommended for longevity.
