In 2013, total volume sales of carbonates increased strongly, rising by 7%. This represented a notable improvement compared to the previous year's growth of 1%, as the category recovered from the strong negative impact of the security crisis in the north of the country, which affected distribution, as well as the fuel price hike of January 2012. It has thus returned to the pre-2012 growth performance, largely due to creative marketing by manufacturers whose introduction of new pack types such as PET bottles helped to revitalise demand. Furthermore, producers of carbonates seem to have acknowledged the threat posed by other soft drinks, such as "nutritious" flavoured milk drinks and juice, and thus are innovating in a bid to offer interesting new juice-based products. This explains the strong performance of the apple-based La Casera brand from The La Casera Co Ltd, for example. These factors aside, carbonates generally performs positively in Nigeria, in line with population growth, given that the hot weather leads to demand for cold, sweet drinks, particularly in roadside vendors and other away-from-home channels.
