Soupy / watery puck

The puck knocks out as a wet slurry rather than a firm dry cake. Common on modern machines.

Why it matters — Usually not a problem. On any machine with a 3-way valve (most modern espresso machines), the valve releases pressure but not all the moisture, leaving a wet puck. This is normal — it doesn't mean the shot was bad.

Good to know

• Don't chase a "dry puck" as a quality indicator. Taste matters; puck firmness doesn't.
• If the puck is soupy and the shot is channelling or tasting weak, address the puck prep — not the puck firmness directly.
