AmBev, InBev's Latin American operation, had a tough first quarter, hit by higher costs and poor weather in Brazil. Earlier this month, Olly Wehring met with Luiz Fernando Edmond, zone president for Latin America North at AmBev, who spoke about the challenges in the home market, the progress and potential of other Latin American countries and the opportunities both for InBev's international brands in Brazil and for AmBev's Brahma brand in the US.
