Understanding Roast Levels

Understanding Roast Levels
By Rohan Vaidya30 July 2026

Light, medium or dark — what the label really tells you, and why the best roast is the one you actually enjoy.

Roast level is the simplest way we talk about how long coffee has been exposed to heat. Light roasts stop early, preserving origin character. Dark roasts go further, trading acidity for body and sweetness of the roast itself.

A light roast tastes like the place it came from — fruit, flowers and tea-like clarity. It is demanding: under-extract it and you get sourness; over-extract and it turns bitter and dry.

Roast is a dial, not a team to pick.

Medium roasts split the difference. They keep enough origin flavour to be interesting, while developing a rounder, caramelised sweetness that plays well with milk.

Dark roasts lean into the process — chocolate, molasses and smoke. The origin fades a little, but you gain body and a forgiving cup that is hard to get wrong.

There is no objectively best level. There is only the dial position that makes the cup you reach for every morning. Try the same coffee at two levels and taste them side by side.

In our Roastery, we keep each coffee on the dial for as long as it stays true to itself. Some coffees are done at twelve minutes, some at sixteen.
