The Grammy-winning group Train has been making waves with its wine club, and now, the trio is taking the next step with its own wine. Starting next week, fans will be able to buy Drops of Jupiter Petite Sirah wine from Train's online wine club and other outlets. The name is a nod to one of Train's earlier hits, and is produced by the group's wine company, Save Me, San Francisco Wine Co., which takes its title from a Train album.
