Bru maker AG Barr has seen its profit and revenues fizz in the first half and is planning to sell more drinks south of the border through advertising campaigns.
The Scottish drinks firm saw pre-tax profit rise 18.8 per cent to £16m from £13.5m the year before.
Total turnover in the six months to 31 July rose 13.9 per cent to £119.2m compared with £104.7m in the same period of 2009.
That was ahead of the guidance figure of £118m issued at the end of July.
The Irn-Bru brand grew revenue by eight per cent with increased marketing investment in particular in the North of England.
Barr’s exotic fruit drink brand, Rubicon – which it bought in 2008 – increasing sales by 37 per cent in the period.
Chief executive Roger White said: "We want to get more sales in the south. We have a quality product at the right price. In Scotland Irn-Bru is drunk by everyone and we would like to see more people further south drinking it."
