Behind the Beans: How Ublend® Uses Roast Curves to Craft Consistent, High-Quality Coffee

At Ublend®, roasting is where flavour comes alive — and we don’t leave it to chance. Using multiple Brambati roasters, each equipped with advanced computer-controlled roast profiling software, we turn high-grade green beans into perfectly consistent, flavour-rich coffee that’s tailored to your brand.

What Is a Roast Curve?

A roast curve is a temperature-over-time graph used during the roasting process. It tracks how heat is applied to the beans, capturing key stages like:

1. Drying Phase (0–4 min). Beans lose their natural moisture. Even drying ensures the centre and surface roast uniformly, avoiding baked or scorched flavours.

2. Maillard Reaction (4–8 min). This is where the magic happens — sugars and amino acids react, creating caramel notes, body, and aroma. It's the base of complexity in the cup.

3. First Crack (~8–9 min). Beans pop as internal pressure rises. From here, development is key — roast too little, and it’s sour; too long, and it becomes flat or bitter.

4. Development Phase. Post–first crack, the profile is shaped. This is where sweetness, body, and roast intensity come together.

Ublend's Roasting System: Power + Precision

We roast on multiple Brambati roasting systems, each fitted with sophisticated roast management software. This professional-grade setup lets us:

• Design and store roast curves for every blend, single origin, or customer profile

• Track temperature, rate-of-rise, and airflow in real time

• Adjust on the fly or replicate exact curves for total consistency

• Scale up easily — from 10 kg test batches to large-scale production

These systems are trusted by some of the world’s most respected coffee brands — and now, by Ublend private label clients.
