Today, New York-based Heineken USA announced a new partnership with experiential marketing platform, Gratafy, to give complimentary beers to consumers 21 and older in select markets via Facebook and Twitter. The campaign aims to connect fans in social settings through social media in Los Angeles, Chicago, San Francisco and Houston by offering a free Heineken, Heineken Light or Dos Equis at restaurants and bars partnered with Gratafy. The campaign will begin in late August and going through November. Once the offer is activated (or following a brief survey for their time for fans in Los Angeles and San Francisco), fans provide their digital Gratafy code when settling the bill to receive their draft or bottle, the company says.

"Heineken has always put a premium on reaching customers in innovative ways, and we're truly excited about this partnership," said Ron Amram, senior media director of Heineken USA, in a statement. "Facebook and Twitter are areas where our customers frequent the most, and through Gratafy, we're connecting with them in arguably their most social setting, to offer a complimentary Heineken, Heineken Light, or Dos Equis."

On the heels of the recent #SubwaySymphony campaign, consumers in Los Angeles, Chicago, San Francisco, and Houston will be rewarded for opening their world by receiving an opportunity to get a complimentary Heineken lager or Heineken Light. In October, to coincide with Dos Equis' annual Masquerade campaign, customers in Los Angeles and Houston will receive an offer from the Most Interesting Man in the World, himself, for a complimentary Equis draft or bottle, the company adds.

"We are excited to power this revolutionary program, which will offer thousands of consumers an innovative, simple and fun way to experience Heineken's beers at great restaurants and bars," said Brian Erke, chief executive officer of Gratafy, in a statement.
