Roast levels explained:
from light to dark
The roast level is one of the most important levers for taste. It decides whether a coffee tastes fruity and lively or strong and chocolatey — and which brew method suits it best.
What happens during roasting
Green coffee is raw, dense and tastes of very little. Only the heat of roasting transforms it: sugars caramelise, acids break down, aroma compounds form. During roasting you hear a cracking sound — the so-called first crack. How long a coffee is roasted beyond this point determines its roast level.
As a rule: the lighter the roast, the more of the origin character is preserved. The darker it gets, the more the roast flavours themselves come to the fore.
The three roast levels at a glance
Light roast
Stopped shortly after the first crack. Light roasts emphasise origin: lively acidity, floral and fruity notes. They are particularly suited to filter coffee and pour-over.
Medium roast
The balanced middle ground: less acidity, more sweetness and body, notes of nut, caramel or cocoa. Versatile — works in the filter as well as a milder espresso.
Dark roast
Roasted longer, often close to the second crack. Little acidity, strong body, flavours of dark chocolate and roasted notes. The classic choice for full-bodied espresso.
Which roast level suits me?
There is no "better" or "worse" — only preferences. If you enjoy delicate, fruity cups and like drinking filter coffee, light roasts are a great choice. If you prefer it strong, round and familiar, go for medium or dark roasts. You learn the most by comparing different roast levels side by side.
By the way: a dark roast does not automatically mean more caffeine. The caffeine content depends mainly on the bean variety and dosage, not on the roast level.
