Founded in 1919, this firm once washed, labelled and corked bottles of soft drinks by hand, delivering them to local shops by horse-drawn carriage. It now manufactures mineral water and soft drinks under contract for global brands including Coca-Cola, Lucozade Ribena Suntory and Barr, and exports to Ireland, Holland and America. Owner, James Harkness, 55, has invested in four state-of-the-art production lines at its factory in Co Antrim, helped by securing an £11.5m funding package from Santander in 2013. International sales hit £8m in 2017, up more than fourfold on the previous year.
