Volume sales of beer have fallen in Scotland following a ban on bogofs and other multiple alcohol promotions, according to new research. The study by M&C Report’s sister publication The Grocer found that in the first four weeks of the ban, which came into force on 1 October, off-trade beer sales fell 14% by volume in the country compared to the same period in 2010. This was against a decline of just 3% over the same period in England and Wales.
