The Art of Grinding – Where Quality is Decided

Simon Valentin Theis

Before water meets coffee, a fundamental decision is made: the grind size.

It defines extraction time, flow rate, and ultimately the sensory profile in the cup. For Café Salvaje, grinding is not a secondary step – it is a central quality tool.


Why grind size is so crucial

Extraction follows physical laws. The finer the coffee grounds, the larger the surface area, and the faster aromatic compounds dissolve.

However, coffee extracts in phases:


- Fruity acids and bright notes

- Sugars, sweetness, balance

- Bitter compounds and dry components


An incorrectly chosen grind size shifts this balance:


Too coarse → Under-extraction, thin body, dominant acidity

Too fine → Over-extraction, bitterness, dry aftertaste

Precisely adjusted → Structure, depth, harmonious balance


The grind sizes in detail:



Very fine – Moka pot

Consistency: almost powdery

Compact, clear structure

Good balance between body and freshness.

Here, micrometry is decisive. Even minimal deviations noticeably change flow time and intensity.

 

 

Medium fine – Espresso

Finer than filter, coarser than espresso

Brew time: approx. 25–30 seconds

Goal: pressure build-up, dense crema, concentrated aroma


Medium – Hand filter / classic filter machine

Consistency: fine sand

Brew time: 2.5–4 minutes

Goal: transparency, aromatic differentiation, elegant acidity

A grind that is too fine slows down the flow, one that is too coarse makes the coffee taste flat.



Coarse – French Press

Consistency: coarse sea salt

Steep time: approx. 4 minutes

Goal: full body, soft texture

Coarse particles prevent over-extraction because the coffee grounds remain entirely in the water.



Consistency – the silent quality factor

Not only the fineness is relevant, but also the particle distribution. High-quality grinders produce homogeneous particle sizes and reduce "fines".

Irregular grinding leads to simultaneous over- and under-extraction – even with correct settings. Precision in the grinder means reproducible results and consistent quality.


Why Café Salvaje only offers whole beans

Ground coffee loses a significant portion of its volatile aromatic compounds in a very short time. The surface area increases massively, and oxidation begins immediately.

The bean, however, protects its aromas like a natural safe.

Only at the moment of grinding is this potential released.

Those who grind themselves decide:

about intensity

about texture

about balance

about character

 

 

Café Salvaje stands for uncompromising quality.

That's why we don't deliver a predefined grind, but the full potential – in its most original form: as whole beans.

The rest is precision. And precision is luxury.
