Coffee has been the single-minded pursuit here since 2014, when this William Street cafe set out to treat brewing as closer to a science than a service. Signature blends are scientifically roasted and built for espresso, poured alongside a full breakfast-and-lunch kitchen that keeps early hours for the city's workers, opening at 5.30am on weekdays. The room draws a steady following among Rockhampton's coffee obsessives, and the house beans are sold by the bag for home brewing. It reads as a serious specialty operator in a regional city not always known for one, and stays independently run rather than tied to a franchise group. For anyone judging Rocky by its flat white, this is the dependable first stop.
