Every Roast, A Complete Science

A green coffee bean smells of little more than dried seeds. It tastes of almost nothing. Everything you love about coffee (the aroma, the sweetness, the body, the bite) doesn't exist yet. It is created in the roast.

That's why we treat roasting as a science, not a habit. In simple terms, roasting is the process of turning the sugars in a green bean into flavour.

What happens in the roaster

Phase 1: Drying (or yellowing). As the name suggests, this phase drives the moisture out of the green beans. During this phase, the beans turn from green to pale yellow.

Phase 2: Browning (the Maillard phase). Sugars and amino acids react under heat (the Maillard reaction), and sugars begin to caramelise, building sweetness, aroma and colour. The beans turn from yellow to brown.

First crack. An important milestone in the roast. Steam and gas build up inside the bean until it cracks open, and you can hear it.

Phase 3: Development. The final stretch of heat decides the balance of the cup. Stop a little earlier or a little later, and it's a different coffee.

Characteristics of the cup

A cup has three main characteristics:

Bitterness increases as the sugars caramelise.

Acidity rises, then slowly falls as the roast progresses.

Character (the soil, the altitude, the processing) becomes noticeable, then fades the deeper the roast goes.

There's no single right roast. There's only the right roast for that bean, and that cup.

From sourcing to your cup

At Madras Brew, every stage, from sourcing to packaging and logistics, is handled with care. We make sure every bean reaches its full potential in the cup.

Commodity, commercial or specialty, every coffee we roast gets the same specialty-level attention. We make the best out of every bean.

India produces around 3–4% of the world's coffee, yet its native coffees rarely get the recognition they deserve. South Indian filter coffee and Monsoon Malabar are two such examples.

Crafted by a chef. Calibrated like a science.
