Companhia de Bebidas das Américas (AmBev), Brazil's largest brewer, has boosted its leading position in the domestic beer market, according to data from Nielsen.

Brazilian daily O Estado de S. Paulo, reported that in May, AmBev's market share was 67.5%, up 0.4 of a percentage point from the previous month.

However, Mexico's Femsa, which sells Kaiser and Sol in Brazil, lost ground last month, with its share declining to 7.8%, from 8.2% in April.

O Estado reported that Cervejaria Petrópolis, which owns the Itaipava and Crystal brands, saw its share jump a full percentage point, to 9.1%.

Each point in Brazil is equal to R$100m (US$61m) in sales.

Cervejaria Schincariol remains in second place, with a 12% share. Schincariol, however, still hasn't incorporated the 0.8 of a point held by Cintra, which it acquired in early May.
