Sore heads woke up on new year’s day in Russia to new restrictions on beer sales. No more booze runs after 11 p.m., and kiosks are now subject to limits on how much beer they can sell. Russia has to do something to curb the alcoholism that claims the life of one in five of its males, according to the World Health Organization. These measures will not be welcomed by brewers, however. The big four – AB InBev, SABMiller, Heineken and Carlsberg – all rely on growth in beer drinking in emerging markets to help offset declining sales in Western Europe.
