Hard Lines roasts in Cardiff and pours from this market counter. Order a V60. It's the closest you'll get to the source.

The guest espresso slot rotates through named producers, with barista write-ups that explain the origin, the processing method, and what you're actually drinking. Serious sourcing for a city-centre stop.

Cardiff's own roastery, operating out of the Victorian Royal Arcade. The team roasts what they serve, and the staff understand the sourcing well enough to tell you about it.

Own roastery, live barista school running from the same Queen Street building. If you want a well-made espresso drink in Cardiff city centre, this is the address.

Cardiff city centre doesn't have many places where you can order a pour-over and have it treated as a serious drink. This is one of them.

Quantum hand-roast in Cardiff Bay and pour the results from this City Centre shop. The single-origin list runs from Peruvian lots to Yemen Mocca Sanani and Jamaica Blue Mountain, which is not a shelf you find often.

A cabin in Gorsedd Gardens where the staff will talk you through what's in the cup before you commit. The retail bags of Brodies-branded beans on the counter tell you this is a project, not a stop-off.

Rotating seasonal specials and a barista who'll talk you through every option before you've made up your mind. Better coffee than anything else in the St Davids Centre.

The loyalty makes sense once you've had the espresso. Bar-cafe in a shopping centre, but someone back there takes the coffee seriously.

The flat whites have actual tasting notes: mellow, nutty, a thread of fruit. Worth tracking down inside Jacobs Market.

The independent option at Cardiff Central. Flat whites come with proper micro-foam and a blend that runs chocolate and biscuit rather than just brown.

Castle Arcade is one of Cardiff's finest Victorian covered arcades, and Coffee Barker is the right place to stop inside it. Single-estate organic Arabica, properly sourced if not obsessively annotated.
