One of Australia’s most celebrated coffee roasters brings its world-class precision to Melbourne.

Ona Coffee: The Art and Science of the Perfect Cup

Founded by World Barista Champion Sasa Sestic, Ona Coffee sits at the intersection of craft and chemistry. The Melbourne flagship is sleek, calm and deliberate — the sort of space where every sound and movement feels purposeful. Sunlight cuts through soft timber tones as baristas move like clockwork behind the counter, dialling in coffees with the precision of lab technicians. It’s both a café and a classroom, where curiosity is part of the experience.

The atmosphere is inviting but focused, a reflection of the team’s deep respect for their raw ingredient — coffee at its most expressive and complex.

The Coffee: Championship-Level Detail

At Ona, you don’t just order coffee — you explore it. The menu is structured by flavour profiles rather than regions, letting you choose based on whether you want something bright, creamy, or fruit-forward. Beans come from meticulously sourced farms, many part of the team’s own Project Origin initiative. The “Reserve” and “Paragon” offerings showcase rare lots and experimental processes, brewed through equipment that looks closer to scientific glassware than café gear.

Every cup is explained with quiet confidence, and somehow it never feels pretentious — just passionate.

The Experience: Precision with Heart

Despite the technical depth, the service remains grounded. Staff guide guests through flavour notes and brewing methods with genuine warmth. Whether you’re drinking a silky flat white or a rare anaerobic Ethiopian filter, there’s a sense of being part of something considered and human. The space is built for reflection — a place to slow down, taste, and appreciate the endless detail behind one of life’s simplest pleasures.

Ona Coffee doesn’t chase trends; it defines the standard that others follow.
