Schincariol's challenge to AmBev's market share suffered a setback in December, according to figures announced this week, local press reported.

Nielsen research institute will release figures later this week showing that Nova Schin, Schincariol's main challenger to AmBev's dominance of the domestic market, held a 13.4% stake in December, the same as it held in November.

AmBev's brands, however, have recovered after three consecutive months' slide. Skol, one of AmBev's main brands, had 31.3% market share in September, but saw that erode in October to 30.4% and 29.9% in November. In December, Skol reversed the slide, grabbing 30.1% share.
