Single O,
Surry Hills.

A Sydney specialty-coffee business established in 2003, with a long-running Surry Hills presence and a range spanning dependable blends and short seasonal releases.

Why it matters

Single O describes its start as a small Sydney roasting operation in 2003, working with its first 15-kilogram roaster, nicknamed Big Boris. More than two decades later, the business remains closely associated with Surry Hills and presents itself around coffee sourcing, roasting and café innovation.

For home brewers, the practical attraction is range: familiar espresso blends sit beside rotating and limited coffees, with product pages that commonly include a suggested recipe.

Surry Hills café

The official café page lists the flagship at 60–64 Reservoir Street, Surry Hills, NSW. Hours and service formats can change, so confirm them directly before travelling.

Where to start

For a daily espresso

Look first at the core blends and choose by the roaster’s milk or black-coffee guidance. A blend is usually the easier place to establish a repeatable grinder setting.

For a seasonal comparison

Firecracker is the more exploratory option in the current edit. Single O’s present edition combines coffees from Papua New Guinea, Peru and Colombia and labels the flavour direction “Cherry Bomb!”.
