South Koreans increased their alcohol outlay by 5% last year, the country's biggest spend for at least a decade, according to a local report.

Official statistics released yesterday showed that households spent an average KRW11,267 (US$10.10) on alcoholic beverages in 2014, compared to KRW10,751 in 2013, Yonhap newspaper said. It was the highest since records began, in 2003.

Beer and soju demand were the main drivers of the increase, along with home consumption of imported wine and spirits.

The survey was conducted on households with two or more members.

Diageo is currently in talks with South Korean authorities over an outstanding tax bill for Windsor Scotch whisky imports.
