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.

Cardiff Bay hand-roasters since 2015, with Yemen Mocca Sanani on the shelf.

Hard Lines Market★★ Specialty

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

Corner Coffee★★ Specialty

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.

Uncommon Ground Coffee Roastery★★ Specialty

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.
