Brecon Carreg
Brecon Carreg is a natural mineral water bottled at source in the Brecon Beacons National Park, Wales. The brand was founded in 1978 and has drawn from the same protected catchment since. The Belgian water group Spadel owned Brecon Carreg for a period; the brand subsequently returned to Welsh ownership through a management buyout. It is positioned as Wales’s leading bottled water brand.
