Plzensky Prazdroj has unveiled plans to increase its beer prices due to a rise in raw material costs.

The brewer will raise beer prices between 6% and 8% in November after a price hike in malting barley and hops on the European market.

The Czech brewer, which is controlled by SABMiller, told just-drinks today (14 September), that "going forward our focus is to make sure we are strategically well-positioned in what we feel is a critical time in the supply base by sourcing new growing regions and being better at leveraging our scale in how we procure packaging materials and in creating new sources of supply".

SABMiller said: "Average market increases on barley from 2006 to 2007 are 38%. This has been exacerbated in the current year by a combination of 2 poor crops in Europe in 2006 and Australia."

Last month Plzensky Prazdroj declared an increase in sales volumes in its half-year sales results due to exports and an early start to the summer. The company said that combined domestic and export sales volumes in the first six months of this year exceeded 4.5m hectolitres, reflecting a year-on-year increase of 5.4%, and making it the largest beer exporter in the Czech Republic.

Sales were driven by a 12.5% lift in export volumes, hitting 430,000 hectolitres.
