Blind basket

Also known as blind filter · cesta ciega · blind portafilter basket

What it is and what sets it apart: Maintenance tool—not for extraction. Differs from the service basket.

At the bar: Insert in portafilter → water/detergent backflush → remove and rinse everything.

Impact on the drink: Impact: deep grouphead cleaning without full teardown each time.

Technical notes: Store clean and dry. Don’t “test pressure” without a protocol.

Common mistakes: Brewing coffee with a blind basket. Leaving detergent inside. Endless cycles.
