Bar water quality

Also known as brew water · agua de barra · water for espresso

What it is and what sets it apart: Dial-in assumes stable water. Not “any bottled water”—specialty targets matter.

At the bar: Filter/condition per café protocol; check filters; don’t run pure distilled in the boiler.

Impact on the drink: Impact: sweetness, mineral perception, scale and equipment life.

Technical notes: Align with tech on TDS/alkalinity. Replace cartridges on time.

Common mistakes: Ignoring a spent filter. Mixing waters without recalibrating. Late descaling.

Work from a logged recipe, scale and a clean station.

Steps

  1. Prep equipment and confirm the target recipe.
