Before the first drop.

Enter the extraction

CREMA — 9 Bars

A study of pressure,
resistance and release.

A landscape
of resistance.

Fractured surfaces.
Uncounted spaces.

ROASTED CELLULAR MATTER

Packed.
Never solid.

Between the particles,
an invisible architecture.
Water will find its way.

PORE SPACE

A boundary
begins
to move.

Water enters the spaces between.

SATURATION FRONT

9BAR

A classical reference. A variable profile.

No two paths
are equal.

Resistance gives
the water a shape.

FLOW THROUGH THE VOIDS

Water
becomes
more.

It enters clear.
It leaves carrying a world.

DISSOLVE / CARRY / CONVERGE

All of that.
In this.

Every path. Every particle.
One departure.

Resistance
becomes
a line.

Dark at the centre.
Amber at the edge.

Gas, held
briefly
in liquid.

A fragile surface.
A changing world beneath.

CO₂ / LIQUID / OIL

An entire
landscape.

A few dozen millilitres.

Pull it again

Build the pressure. Find the path. Pull the shot.

CREMA

Follow
the water.

A journey through particles,
pressure and possibility.

About this study

Nine bar is the classical reference for this work. Pre-infusion and pressure profiles vary.

The coffee bed is a porous material. Crema contains CO₂-rich bubbles within a liquid carrying extracted compounds, microscopic oils and fine particles.

Flow fields and microstructures are authored interpretations informed by coffee research.
