The Logic of Coffee

Espresso Terminology 101

Extraction

The process of dissolving flavor compounds from coffee grounds into water. Under-extracted coffee tastes sour; over-extracted tastes bitter. The goal is the sweet spot in the middle.

TDS (Total Dissolved Solids)

A measure of the concentration of coffee in your cup. Espresso typically ranges from 8-12% TDS, while filter coffee is around 1.2-1.5%.

Crema

The reddish-brown foam on top of an espresso shot. It's formed by CO2 bubbles emulsified with coffee oils. While beautiful, it's actually the most bitter part of the shot.

PID Controller

A mechanism that precisely controls brew temperature. Unlike simple thermostats, a PID minimizes temperature fluctuation, which is critical for consistent espresso.

Common Questions

Why is my espresso sour?▼

Sourness usually indicates under-extraction. The water passed through the puck too fast or wasn't hot enough. Try grinding finer (to slow down the flow) or increasing your brew temperature.

Do I really need a burr grinder?▼

Yes. Blade grinders chop beans unevenly, creating "boulders" (under-extracted) and "fines" (over-extracted) in the same basket. A burr grinder ensures uniform particle size, which is essential for consistent espresso.

How fresh should my beans be?▼

For espresso, we recommend beans roasted between 7 and 30 days ago. Freshly roasted beans (days 1-6) are gassy and hard to dial in. After 30 days, they lose the crema and complex aromatics.
