2. Evian

Evian is a longtime sponsor of the South Beach Wine & Food Festival, which takes place this year on Saturday and Sunday. Leading up to the festival, the brand has partnered with Live Young to launch a social media campaign with chef Richard Blais, using Instagram for its #evianeats photo activation. The chef has already started sharing daily culinary photos via @evianwater to promote the hashtag; once the festival kicks off, he'll post daily pictures via #evianeats.
